Description

The lubricant surface treated metal substrate material of plasticity and welding property excellent

Technical field

The present invention relates to a kind of lubricant surface treated metal substrate material, particularly relate to all excellent lubricant surface treated metal substrate material of plasticity and weldability.

Background technology

General present widely used metal base, in order not have problems when the shaping processing of carrying out structure unit, goods from base material or the assembling, it has excellent plasticity, weldability strong request.Stainless steel for example, owing to have good anti-corrosion, can be widely used in various water circle devices, chemical reaction tower, waste liquor treatment equipment, transfer limes etc. such as boiler that family, office, factory etc. use, hot water supply apparatus, washing device, washing machine, kitchen, reservoir, handle therefrom low temperature to the industrial equipments of the various liquid of pyritous, in addition, also can be widely used in the erosion resistance structure unit of marine structure, automobile, rail vehicle, boats and ships etc., in order to be processed into structure unit, require it to have remarkable plasticity and weldability.In addition, powering up OA, automobile, building materials field, also more use than the corrosion-resistant steel plating of zinc class of stainless steel cheapness or the corrosion-resistant steel plating of aluminium alloy class as metal base, under this kind situation, in order to be processed into structure unit, also must have good plasticity, weldability.Further, in order to realize the lightweight of automobile or rail vehicle, boats and ships etc., require metal bases such as the aluminium of its use or aluminium alloy also to have good plasticity, weldability.

When utilizing the die forming metal base, if the oilness deficiency of metal base will crack, pleat and because therefore the problems such as surface damage that mould adhesion etc. produces will be coated with lubricating oil before shaping.Use this method, before shaping, must be lubricated the painting process of oil, utilize various organic solvents or alkaline degreasing fluid etc. to remove the operation of washing lubricating oil and further after shaping, must have, therefore this manufacturing process is not only miscellaneous, and the solvent or the degreasing fluid that use in the washing procedure removing of lubricating oil, health or environment to the operator can produce bigger load, are not very desirable therefore.

As not with an organic solvent or degreasing fluid just can form the lubricant surface treated metal substrate material of desirable shape, proposed on metallic substrate surface, to have formed the base material of the lubricating resin epithelium of lubricating function imparting agents (giving the material of lubricating function) such as the content of wax or solid lubricant.For example, for the motion of stainless-steel sheet, have the spy to open the 2002-60972 communique, for the motion of galvanized steel plate, have the spy to open flat 7-96576 communique, the spy opens flat 8-156174 communique etc., and same technology can be used for various metal bases.This lubricant surface treated metal substrate material, by with the gauge control of lubricating resin epithelium about 0.8～1.2 μ m than close limit in, though attempt to obtain the plasticity of metal base and the balance of 2 pieces of overlapping weldabilities, but in fact find not satisfy simultaneously the condition of this two aspect of good plasticity and weldability at all, perhaps very narrow for satisfying the processing window (processing window) of good plasticity and these two aspects of weldability, stablize and obtain comparatively difficulty of good plasticity and weldability.Because influence the factor of weldability, additive in the kind of the thickness of the lubricating resin epithelium that not only only on metallic substrate surface, forms but also kind, tissue, material, surfaceness or the lubricating resin of metal base, material, the resin, the lining situation of lubricating resin epithelium, and various conditions such as the material of electrode, shape, plus-pressure, welding current also about greatly the temperature rising situation of weld part.

The lubricant surface treated metal substrate material that will form the lubricating resin epithelium on the surface of metal base is processed in structure unit or the goods, do not have only two overlapping welding, the situation that 3～4 or the overlapping portion of multi-disc more than it weld is also more.Can stablize by the thickness of sight-feed lubricator resin involucra and to obtain good plasticity and this part thing of weldability, for the overlapping welding of such multi-disc, many than the situation difficulty of above-mentioned two overlapping welding.Because in the overlapping welding of multi-disc, the metal base that is connected with electrode at place, eclipsed two ends, and between the metal base of overlapping inside, accept the difference such as distribution, the influence of electrode pair refrigerative of stressed distribution, the electric current of electrode, the electric current of the base material that flowed or temperature distribution are than the situation complexity of two overlapping welding.

In addition, as having applied the metal base that the mineral-type lubricated surface is handled, having on the surface of metal base of having proposed form contain the lubricating function imparting agent the mineral-type epithelium (for example, to stainless-steel sheet, open the 2003-41380 communique with reference to the spy) or the base material of lining oilness inorganic epithelium, (for example to the motion of galvanized steel plate, there is the spy to open flat 9-256169 communique, Te Kaiping 5-214558 communique, in addition, for the motion of aluminium sheet, open flat 5-320932 communique with reference to the spy), same technology can be used for various metal bases.Even thisly applied the metal base that the mineral-type lubricated surface is handled, when 3～4 or the overlapping welding of multi-disc more than it, stablize by the thickness of managing the mineral-type epithelium and to obtain good plasticity and weldability also is difficult.

Improve weldability when keeping the plasticity of lubricant surface treated metal substrate material, proposed organic class of all reductions or mineral-type lubricating film lining rate, guarantee the scheme of energising property at the position of the epithelium that is not covered to metal base.(for example to galvanized steel plate, open flat 4-56783 number, spy with reference to the spy and open flat 5-237451 communique,, open flat 6-262721 communique with reference to the spy for stainless-steel sheet.), same technology can be used for various metal bases.But, with such method at the discontinuous epithelium that only is covered on the metallic substrate surface during in welding, energising resistance heterogeneity ground descends, want in complicated 3～4 or the overlapping welding more than it comparing the electric current that flows through metal base or temperature distribution with two overlapping welding, stablize and obtain comparatively difficulty of good plasticity and weldability.

As mentioned above, though attempted between the plasticity of the lubricant surface treated metal substrate material that forms organic class or mineral-type lubricating film and two overlapping weldabilities, averaging out, but when 3～4 or multi-disc lap more than it are welded, the stable good plasticity and the technology of weldability of obtaining still do not found up to now.

Specific embodiments

Below the present invention is described in detail.

Lubricant surface treated metal substrate material of the present invention, owing to be to have formed the lubricating resin epithelium at least a portion of metallic substrate surface of 0.03～1.5 μ m at arithmetic average roughness, on original metallic substrate surface, imposed the lubricated surface into treatment sites that forms the lubricating resin epithelium and be " lubricated surface processing " position.As the lubricant surface treated metal substrate material among the present invention, there is the integral body of lubricated surface into treatment sites to be coated with the base material of lubricating resin epithelium, and on the lubricated surface into treatment sites, is coated with the zone (C zone) of lubricating resin epithelium and do not have the base material of zone (UC zone) coexistence of lining.Under the former situation, the whole complete lubricated resin involucra of lubricated surface into treatment sites covers, and metallic substrate surface is not originally exposed fully.Under the latter's situation, the lubricated surface into treatment sites is made up of C zone and two zones, UC zone, the C zone is meant that lubricated resin involucra covers fully, the zone that metallic substrate surface is not originally exposed fully, the zone that the UC zone is meant does not in addition have the lubricating resin epithelium, original metallic substrate surface is exposed.

Among the present invention, the arithmetic average roughness that forms the metallic substrate surface of lubricating resin epithelium is 0.03～1.5 μ m, is preferably 0.05～0.5 μ m.The following describes its reason.

The lubricating resin epithelium that on metal base of the present invention, is covered, be when lubricant surface treated metal substrate material is shaped on metallic substrate surface coating can form and have no oiling oilness (, can not guarantee oilness even be not coated with lubricated wet goods during shaping yet) solvent borne of epithelium or aqueous resin composition (below, all be designated as the oilness cold coating or simply be designated as coating), heating makes it to react, the dry film that forms.The lubricating resin coating that is coated with on metallic substrate surface is because landfill is in the recess of the small fluctuating of metallic substrate surface, so the coating that is detained at recess is more than protruding place.When the roughness levels of the average leather film thickness of the lubricating resin epithelium that forms after the coating drying and original metallic substrate surface did not have a great difference, because the wettability of coating constituent, coating and metallic surface, drying conditions etc. are different, on degree, there are differences, but there is the epithelium position that covers original metallic substrate surface recess to become big tendency than the epithelium part leather film thickness that covers protuberance, according to different situations, do not covered and expose in the part of metallic substrate surface protuberance sometimes by epithelium.On the other hand, the average leather film thickness of the epithelium that forms after the coating drying is compared with the roughness levels of original metallic substrate surface sizable the time, the tendency of the stronger dependency of existence between the average leather film thickness of the epithelium that forms when having leather film thickness to distribute to become concavo-convex and the coating of not seeing original metallic substrate surface dry.In addition, the mean thickness of the epithelium that after the coating drying, forms and original metallic substrate surface roughness levels compare quite little in, the leather film thickness that has or cover the metallic substrate surface protuberance becomes thin especially, and perhaps the protuberance majority of metallic substrate surface exposes and tendency that whole coating film rate is reduced.

Among the present invention, when the integral body of lubricated surface into treatment sites was coated with the lubricating resin epithelium, as described later, the average leather film thickness of lubricating resin epithelium must be between 0.1～0.9 μ m.Therefore, when the arithmetic average roughness of metallic substrate surface is discontented with 0.03 μ m, the average leather film thickness in the zone of lining lubricating resin epithelium, compare with the roughness levels of metallic substrate surface and to become quite big, and with original metallic substrate surface concavo-convex it doesn't matter, the tendency of the thick distribution of epithelium that can form the comparison homogeneous is arranged.Therefore in the lubricated surface into treatment sites, the ratio that exists in the special thin zone of leather film thickness becomes considerably less, when the overlapping welding of such metal base, even on overlapping part, push electrode because therefore difficult destruction epithelium is difficult to guarantee to switch on some the weldability variation.On the other hand, when the arithmetic average roughness of metallic substrate surface surpasses 1.5 μ m, because the average leather film thickness of lubricating resin epithelium becomes and compares much smallerly with the roughness levels of metallic substrate surface, the integral body of the lubricated surface into treatment sites that therefore will be covered fully is difficulty comparatively.Even the arithmetic average roughness of metallic substrate surface surpasses 1.5 μ m, also exist in the possibility of the lubricating resin epithelium that is covered on the whole of lubricated surface into treatment sites, but this moment, the epithelium that is overlayed on the metallic substrate surface protuberance becomes thin especially, during shaping from mould than being slided under the strong pressure or swiping, epithelium is easy to generate and breaks, the plasticity variation.

In addition, in the present invention, when the lubricated surface into treatment sites coexisted with the zone (UC zone) that does not have lining in the zone (C zone) of the lubricating resin epithelium that has been covered, as described later, the average leather film thickness in above-mentioned C zone must be between 0.2～1.2 μ m.Therefore, when the arithmetic average roughness of metallic substrate surface is discontented with 0.03 μ m, the average leather film thickness in lubricating resin coating film zone becomes more much bigger than the roughness levels of metallic substrate surface, and with original metallic substrate surface concavo-convex it doesn't matter, have to form the tendency that the leather film thickness of homogeneous comparatively distributes.Therefore, in the lubricated surface into treatment sites, the ratio that exists in the UC zone of excellent electric conductivity tails off, and in the overlapping welding of such metal base, also is difficult to guarantee to switch on fully point, energising area, weldability variation even push electrode on overlapping part.On the other hand, the arithmetic average roughness of metallic substrate surface is when surpassing 1.5 μ m, in the lubricated surface into treatment sites, because the average leather film thickness in C zone is compared with the roughness levels of metallic substrate surface and is become quite little, therefore exposing that the protuberance of metallic substrate surface is more forms the UC zone, when being shaped for not bringing into play oilness, the plasticity variation than slip under the strong pressure or scraping from mould.

Here, the arithmetic average roughness of metallic substrate surface among the present invention is the defined arithmetic average roughness Ra of JIS B0601-2001 (definition of presentation surface roughness).Arithmetic average roughness Ra is utilizing the contact pin type transmitter describing to be tested the device (commercially available roughness tester) that surface shape is measured in the use of back, surface, mensuration that can be more or less freely.

To the control of the arithmetic average roughness of the metallic substrate surface used among the present invention, can use any method.For example can enumerate, utilize rolling concavo-convex (arithmetic average roughness is the scope of 0.03～1.5 μ m) of solid metal to be transferred to the method on the metallic substrate surface with the Rolling roller surface, concavo-convex (arithmetic average roughness is the scope of 0.03～1.5 μ m) with die surface when metal casting is transferred to the method on the cast member, to the surface utilization acid of metal base, alkali lye or electrolytic solution etc. carry out the method for chemical milling, and utilize sandblast or water-jet etc. to carry out mechanical mill, make it form the concavo-convex method of arithmetic average roughness in 0.03～1.5 mu m range etc.

Among the present invention, when the integral body of the lubricated surface into treatment sites that has formed the lubricating resin epithelium was coated with the lubricating resin epithelium, the average leather film thickness of lubricating resin epithelium was 0.1～0.9 μ m, was preferably 0.2～0.7 μ m.When average leather film thickness was discontented with 0.1 μ m, thickness was thin excessively, and the oilness deficiency can not prevent the damage that reaches metallic substrate surface of pushing when being shaped, and it is bad to be shaped.When average leather film thickness surpassed 0.9 μ m, even push electrode on overlapping part in overlapping welding, also difficult damaged thereby difficulty guarantee to switch on fully point, the energising area of epithelium welded often bad.

Among the present invention, when the zone (UC zone) that is coated with the zone (C zone) of lubricating resin epithelium and does not have to be covered on the lubricated surface into treatment sites coexists, " the average epithelium in C zone is thick ", be meant～area in UC zone is removed the leather film thickness that the area of only considering the C zone obtains when getting its mean value from the thick calculating object of average epithelium.Be somebody's turn to do " the average leather film thickness in C zone " between 0.2～1.2 μ m, between preferred 0.3～0.9 μ m.When the average leather film thickness in C zone was discontented with 0.2 μ m, leather film thickness was thin excessively, the oilness deficiency, and the damage of pushing the arrival metallic substrate surface in the time of can not preventing to be shaped, it is bad to take place to be shaped.As described later, the maximum width of the metal covering that expose in each UC zone among the present invention or maximum diameter are at most about 120 μ m, and the size that contacts with metallic substrate surface with electrode in overlapping welding (several mm footpath or more than it) is compared, and is much smaller.Therefore when the average leather film thickness in C zone surpasses 1.2 μ m, hindered owing to be positioned at the pachydermia film in the C zone around the UC zone, electrode can not touch the metal covering that expose in the UC zone fully, and rack of fusion often takes place.

In the metal base of the present invention, the mensuration of the average leather film thickness in C zone can be used any method.For example can on the metallic substrate surface that forms the lubricating resin epithelium, utilize the sem observation vertical cross-section, try to achieve average leather film thickness by the observations in most cross sections.As more high-precision measuring method, following method is for example arranged.About the judgement that contains rate (unit mass %) in epithelium in the formation element of the lubricating resin epithelium that on original metallic substrate surface, forms, be the adhesion amount (g/m of unit by obtaining per unit area ²), the epithelium adhesion amount (g/m of unit that calculates the lubricated surface into treatment sites integral body of forming by C zone and UC zone ²).In addition, two-element list surface analysis by the lubricating resin epithelium that forms on metallic substrate surface can be in the hope of the occupation rate (=coating film area occupation ratio) in C zone, from the proportion of these results and epithelium, can be in the hope of the average leather film thickness (the μ m of unit) in C zone.In these methods, epithelium constitutes the adhesion amount of element, can utilize for example feature of this element (fluorescence) X ray strength analysis to try to achieve.In addition, the occupation rate in C zone for example in metallic substrate surface, utilizes EPMA (Electron ProbeMicroAnalyser) to try to achieve 2 yuan of distributions that epithelium constitutes the characteristic X ray strength of element, thereby tries to achieve the ratio in lining epithelium zone.Epithelium proportion, for example can utilize acid etc. only to dissolve, remove the metal of lubricant surface treated metal substrate material after, a spot of leather diaphragm is encased in the density gradient tube tries to achieve.

Among the present invention, shape for the UC zone is not particularly limited, can be simple shape such as ellipticity, band shape, perhaps (perhaps in the C zone) C zone (perhaps UC zone) is sea-island shape that island distributes in the UC zone, the different shapes such as shape that the mutual intricately in UC zone and C zone mixes.But, for the size in UC zone qualification is arranged, begin from the optional position in the UC zone to UC zone and C zone must be at 60 μ m or below it, preferably at 40 μ m or below it near the slant range on border.When the UC region memory surpasses the position of 60 μ m near the slant range on border in UC zone and C zone, when being shaped, contact more on a large scale between metallic substrate surface and the die surface, thereby on the metallic surface, easily produce the flaw that bonds, it is bad to be shaped.Above-mentioned slant range is meant when surpassing 60 μ m, for example Yi Xia situation.Be simple when oval in the UC zone, oval short radius surpasses the situation of 120 μ m.When being banded merely in the UC zone, at least a portion bandwidth surpasses the situation of 120 μ m.When being the island distribution in the marine C zone in UC zone, at least 1 C zone that is island is to the situation of the shortest distance between another C zone above 120 μ m.Above-mentioned slant range for example when above-mentioned EPMA is applicable to metallic substrate surface, is tried to achieve 2 yuan of distributions that epithelium constitutes the characteristic X ray strength of element, extracts not exist epithelium to constitute the zone (=UC zone) of element in the distribution plan, tries to achieve by parsing.

Among the present invention, the total area in UC zone, 45% or its following (being that the coating film rate is 55% or more than it) of preferably accounting for the metallic substrate surface integral body that has imposed above-mentioned lubricated surface processing are more preferably 30% or below it.When UC zone surpass above-mentioned metallic substrate surface integral body 45% the time, shape and distribution according to these UC zones, sometimes metallic substrate surface easily directly contacts with die surface when being shaped, and easily produces the bonding flaw in metallic substrate surface, may cause that shaping is bad.For imposing the whole UC area occupied of the metallic substrate surface ratio that lubricated surface is handled, for example when above-mentioned EPMA is applicable on the metallic substrate surface that has imposed the lubricated surface processing, do not exist epithelium to constitute the zone of element by extracting, can more easily try to achieve this area ratio.

Formation method as lubricating resin epithelium of the present invention, after utilizing known coating processs such as rolling method, spraying method can form the solvent-borne type of above-mentioned epithelium or water-base resin coating to be coated on the metallic substrate surface, form epithelium by the heat drying solvent or by sintering reaction.

Coating process or application condition according to cold coating, be coated with the situation of lubricating resin epithelium in the integral body of the lubricated surface into treatment sites that has imposed the lubricated surface processing that forms the lubricating resin epithelium, and the zone (C zone) of the lubricating resin epithelium that on the lubricated surface into treatment sites, has been covered and the situation that the zone (UC zone) that does not have lining coexists, can not separate application merely.But, the wettability of coating and metallic substrate surface better, coating composition is with the reactive height of metallic substrate surface, when reacting fast after application, even the average leather film thickness of the lubricating resin epithelium that forms is compared quite little with the roughness levels of metallic substrate surface, the integral body that the lubricated surface into treatment sites is also arranged is by the tendency of average leather film thickness at 0.1 μ m or the lubricating resin coating film more than it.

In the lubricant surface treated metal substrate material of the present invention, the metal base kind that forms the lubricating resin epithelium is not particularly limited base materials such as the alloy that aluminium, titanium, zinc, copper, nickel is arranged and contain these metals for example applicatory, steel.Wherein, when using steel, component being not particularly limited, can being common iron, also can be chrome-bearing steel materials such as stainless steel steel, also can be to contain the steel that other add element.In addition, also can be the plating steel that on the surface of steel, have lining coating.Wherein, as preferred metal base, common iron, stainless steel steel, plating steel, aluminium or aluminum alloy materials are arranged.
