Description
【Technical field】
The invention belongs to steel surface chemical heat treatment technology field, and in particular to a kind of high rigidity, corrosion resisting property are strong
Powder zincizing product.
【Background technology】
Traditional " steel piece powder zincizing technology ".Powder zincizing is also known as hot zincizing, is solid-state multicomponent thermochemical treatment surface peening
One kind in technology.Solid-state multicomponent thermochemical treatment surface strengthening technology is the diffusion effect for utilizing metallic atom under heated condition,
One or more metallic elements are penetrated into metallic article surface and form an a kind of class chemical heat treatment process of alloy protective layer,
The protective coating that this technique is formed is referred to as thermal diffusion coating by the U.S.ASTM standard published for 2008, passes through thermal diffusion coating
Handling process can be obviously improved that metal material surface is corrosion-resistant, wear-resistant, anti-oxidant and the performance such as shock resistance, effectively expand
The application of big metal material.
Powder zincizing is exactly a kind of specific thermal diffusion surface strengthening technology, and it is diffused into using Zn-ef ficiency under heated condition
Enter a kind of chemical heat treatment process that steel structural part surface prepares zn-fe alloy protective layer, powder zincizing coating can be effective
Improve the anticorrosive of steel structural part surface, resistance to surface oxidation and abrasion resistance properties.Comprehensive analysis machinery industry standard
JB/T 5067-1999《Steel piece powder zincizing》, European standard EN13811-2003《The zinc diffusion coating of ironwork is detailed
Specification》And the data such as domestic/external sherardising process, before the typical process flow of domestic/external powder zincizing mainly includes
3 processes such as processing, hot zincizing and post processing.
Pre-treatment for the greasy dirt of article surface, rusty stain are cleaned out, the process typically used be pickling, shot-peening or
Sandblasting, but this 3 kinds of methods have different limitations.
Pickling is greasy dirt, the rusty stain that steel piece surface is removed by the method for chemical reaction, but simultaneously can be chemical anti-
Hydrogen atom is produced during answering and is entered in steel piece.Because hydrogen atom activity is very big, its activity everywhere in product can be produced
Raw 2 kinds of consequences：1) product is under force-free state, and hydrogen atom is assembled in product forms hydrogen molecule, and hydrogen molecule is at accumulation position
Expansion produces internal stress, and then product is produced hydrogen embrittlement micro-crack, causes easily to be broken during product stress.2) product is in stress shape
Under state, hydrogen atom is movable in product, builds up as hydrogen molecule.Hydrogen molecule produces internal stress in the expansion of accumulation position, and then
Product is produced hydrogen embrittlement delay micro-crack, be easily broken after causing product stress.Therefore, this method is generally not suitable for machining
Steel piece.
Shot-peening or sandblasting are greasy dirt, the rusty stain that steel piece surface is removed by the method for continuous machinery strike, but simultaneously
Mechanical damage can be left in article surface.For the not high product of surface requirements, this kind of method can be applicable；Can not for surface
The product of mass lesions, this kind of method can not be applicable.And the surface of steel piece is machined typically by processing, shot-peening
Or sandblasting can damage the form and position tolerance and configuration of surface of product, thus this method is generally not suitable for machining steel piece.
As known from the above, the technique such as pickling, shot-peening or sandblasting is not suitable for before machining steel piece powder zincizing
Processing.
Heating zincizing is to mix steel piece, zinc powder and inertia impact media to be filled in sealed rustless steel container,
And container is placed in heat-treatment furnace, 360-450 DEG C is heated in the case where container rotates and a period of time is incubated, utilized
The diffusion of metallic atom, in component surface formation Fe/Zn alloy protecting layers.
From the process of heating zincizing, it is the process of an average tempering, without introducing hydrogen atom during zincizing
Environment, thus be not in as electroless zinc plating because introduce hydrogen atom caused by hydrogen embrittlement be inclined to.In addition, being inhaled at a temperature of this
Effusion can largely be spread by entering the hydrogen atom of steel matrix, thus have the effect of certain dehydrogenation (>=200 DEG C, be incubated 8-24h).
But most of hydrogen atom can only be removed, it is impossible to remove whole hydrogen atoms, hydrogen molecule can not be removed.Therefore, zincizing process is heated
It can not be completely eliminated due to the hydrogen embrittlement hidden danger that pickling is brought to machining steel piece.
In addition, different from traditional powder embedding chemical heat treatment process (embed product in the powder in inactive state
Lower heating), industrialization sherardising process is heated under continuous rolling condition, between mixture of powders and workpiece
Mechanical friction, percussion not only contributes to the close contact at fresh diffusion penetration enhancer and processed interface, and to be added
Heat medium temperature homogenization, and effectively facilitate metallurgical diffusion chemical reaction.
Product is under continuous rolling, friction, impact conditions, although inertia impact media can play sizable barrier and slow
Punching is acted on, but it is unavoidable occur between product, mutually collided between product and container, between product and frock, cause article surface form
There is light weight damage.Therefore, heating zincizing process can not prevent the configuration of surface damage of machining steel piece.
From upper analysis, conventional powder zincizing technique can make machining steel piece hydrogen embrittlement hidden danger, or big face occur
Accumulate disfiguring workpiece and cause its form and position tolerance and configuration of surface Quality Down, thus be not suitable for being machined steel piece powder
Zincizing, i.e. powder zincizing technology are difficult to the extensive use in machining steel piece.
Outdoor steel structure and fastener, freeway guardrail, bridge, hot-water heating utensil, architectural hardware, automobile, engineering machinery
Deng iron and steel parts, the iron and steel parts used in the engineering such as sintered metal product and chemical industry, ocean, metallurgy, generating, usually
Need corrosion-resistant overcoat.Zinc is most-often used chemical element in steel and iron parts surfacecti proteon：Dip galvanized, thickness typically exists
15-130 μm, member planar has significant difference with corner thickness of coating, and lack of homogeneity is difficult to control；Electro-galvanized layer, thickness is general
At 5-25 μm, plane coating uniformity is good, but the coating of component inside cavity is thin, and sometimes without coating；Thermal spraying zinc layers, thickness
Generally 84-300 μm, also thick 3mm can be reached, thickness evenness is poor, and compactness is low；Sherardised coating, thickness is solely dependent upon zincizing
The technological parameters such as agent, heating-up temperature and soaking time, it is substantially unrelated with the shape of component and position, it is threaded when processing, recessed
During the steel and iron parts of the complicated shape such as groove and endoporus, the thickness of zinc coat is almost identical, and general thickness can be between 10-100 μm
Selection, is accurately controlled near a certain thickness value by adjusting soaking time.
Powder zincizing, is that powder zincizing agent and steel and iron parts are co-located in sealing container, is heated to 400 DEG C or so, makes work
Property zinc atom is internally permeated by the surface of steel and iron parts, and the process of uniform zinc-iron alloy layer is formed on its top layer.Relatively
In other method, the zinc consumption of powder zincizing is low, save raw material；Production process is pollution-free, and working condition is good；Production equipment
Simply, using low with maintenance cost.Powder zincizing has that corrosion resistance is strong, hardness in the zinc-iron alloy layer that steel and iron parts surface is formed
The advantages of high, wear-resistant, scratch resistance, paintability are good.
Burn into corrosion is the natural enemy of ferrous materials.It is lost it is estimated that world's output of steel there are about 1/10th in burn into rust
Erosion.It was verified that under a variety of environment such as marine atmosphere, severe industrial atmosphere, the corrosion resistance of zinc coat is better than galvanizing, electricity
Zinc-plated and stainless steel.Zincizing layer surface Vickers hardness can reach 250-400, and galvanizing, electrolytic zinc-coated steel sheet ironware surface are pure
Zinc, coating Vickers hardness is only 70 or so, therefore zincizing is compared with galvanizing and electrogalvanizing, the surface abrasion resistance of steel and iron parts and anti-
Abrade performance much better.In general, the pre-treatment of zincizing production is only with shot-blasting machine derusting edible vegetable oil, and is removed with cloth bag
Dirt.Powder zincizing technology is oozed for the solid of zinc, is produced without zinc fume, and workpiece enters in closed utensil again with powder zincizing agent
Row infiltration and separation, do not pollute to surrounding environment.According to measuring and calculating, the zinc consumption of hot-galvanized steel ironware ton product is 100 kilograms
Left and right, and powder zincizing is only 30 kilograms or so, only accounts for the 30% of galvanizing.In addition, also corroding this galvanizing without zinc pot
Hard nut to crack.The zinc coat of zincizing product is uniform, and is one-level with the adhesion of paint, can realize to be combined after japanning and prevent
Shield, its corrosion resistance is superior to galvanizing, electrogalvanizing and single zinc coat.The steel product handled through zincizing does not influence material
Mechanical property.The temperature of zincizing processing is lower than galvanizing 100-280 DEG C, and the hydrogen atom that steel matrix is sucked at a temperature of this has spread ease
Go out.Therefore the harm without hydrogen embrittlement in the application, is also avoided that some high intensity parts such as spring mechanics caused by treatment temperature height
The drawbacks of hydraulic performance decline.So, powder zincizing has broad application prospects.
But, the zincizing time that existing powder zincizing agent and its technique for applying need is long；Zinc-iron alloy layer it is corrosion-resistant
Performance can also be improved further；Steel and iron parts surface is bonded with zincizing agent, it is necessary to clear up；Used powder zincizing agent caking, no
It is easy to recycling.
