Nickel sulfate hexahydrate, sodium hypophosphite, a polytetrafluoroethylene emulsion and a wetting agent are prepared as a coating liquid; a plating part treated by the coating is good in abrasive resistance and good in anti-corrosive properties, has weldability and hardenability, does not generate any negative effect on other mold surfaces, can be applicable to various base materials such as steel, copper alloy, forged aluminum, cast iron and stainless steel, and has weldability and hardenability.
Description
Technical field
The present invention relates to coating technology field, particularly relate to the chemically composited coating of a kind of nickel-Teflon.
Background technology
Present mould product often adopts process for modifying surface to improve mechanical property and the work-ing life of mould.The process for treating surface of mould mainly contains anodic oxidation, hard anodizing and application rete.Anodic oxidation is carried out to mould, although form layer oxide film on surface, this oxide film can improve the mechanical property of mould to a certain extent, but prepared oxidation film layer is thinner, less with the bonding force of matrix, surface hardness, generally at about 300HV, can only shield to mould in a short period of time; And oxidation film layer prepared by hard anodizing improves compared with the hardness of common anode oxidation film layer, can reach 450HV, but its processing requirement is very strict, the temperature of general electrolytic solution must control below 5 DEG C.Mould product field of surface coatings, extensively adopt multi-arc ion plating equipment and technology, hallow cathode deposition, HCD equipment and technology etc. both at home and abroad, the coatings such as preparation TiN, AIN, CrN, TiC, TiCN, TiAIN, because its oxidation resistance temperature is low, frictional force is large, with the reason such as basal body binding force is little, application is restricted.
Summary of the invention
In order to solve the problem, the object of the invention is to, provide a kind of nickel-Teflon chemically composited coating, the plating piece using this coating process to obtain not only wear resistance, preservative property is good, and have and can weld and hardenability, any negative impact is not produced to other die surface.
The present invention is achieved through the following technical solutions.
The chemically composited coating of nickel-Teflon, it comprises following component: nickel sulfate hexahydrate 50g-60g/ liter, sodium hypophosphite 12g-17g/ liter, polytetrafluoro alkene emulsion 15g-20g/ liter, and wetting agent 4ml-6ml/ liter; By above component at pH value 3.5, under temperature 65 degrees Celsius of operational conditions, formed by filtration pump circulation stirring.
Preferably, described component is nickel sulfate hexahydrate 55g/ liter, sodium hypophosphite 15g/ liter, polytetrafluoro alkene emulsion 18g/ liter, and wetting agent 5ml/ liter.
Nickel sulfate hexahydrate, sodium hypophosphite, polytetrafluoro alkene emulsion and wetting agent carry out preparing as coating solution by the present invention, the plating piece using this coating process to obtain not only wear resistance, preservative property is good, and have and can weld and hardenability, any negative impact is not produced to other die surface, be applicable to the base materials such as various steel, copper alloy, wrought aluminium, cast iron and stainless steel, and have and can weld and hardenability.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, understands the present invention to help those skilled in the art.
The chemically composited coating of a kind of nickel-Teflon of the present invention, it comprises following component: nickel sulfate hexahydrate 50g-60g/ liter, sodium hypophosphite 12g-17g/ liter, polytetrafluoro alkene emulsion 15g-20g/ liter, and wetting agent 4ml-6ml/ liter; By above component at pH value 3.5, under temperature 65 degrees Celsius of operational conditions, formed by filtration pump circulation stirring.Preferably, described component is nickel sulfate hexahydrate 55g/ liter, sodium hypophosphite 15g/ liter, polytetrafluoro alkene emulsion 18g/ liter, and wetting agent 5ml/ liter.
The wound that the chemically composited coating of this nickel-Teflon is formed wins coating, there is surface lubrication (dry friction coefficient can be low to moderate 0.04), the feature such as anti-stick, corrosion resistant (0.001 inch of thickness of coating also can bear the SaltSprayTest more than 300 hours), wear-resisting (be 14 milligram by the abrasion loss under emery wheel 1 Kg load of TaborCS-10 model), strong hardness (hardness can reach Rockwell 36-62 degree); Be applicable to various steel, the base materials such as copper alloy, aluminium alloy, cast iron and stainless steel, and any negative interaction can not be produced to mould; For various plastic cement, elastomeric material is shaping has very great help, especially PA, PVC, TPO, the exotic materials such as GF (glass fibre), rubber, silica gel, epoxy resin.Different from the coating of other form, the rich coating of wound is not limited in position, mould corner and the distribution of deep trouth hole site, but applies at the real profile surface uniform of mould, avoiding problems the discordance of coating and the attrition process again that causes; B, coating paste firmly: the rich coating of wound prevent from coming off and broken in have superiority very much.Plating postheat treatment, will strengthen attaching firmness further; C, shortening shaping cycle: the dry friction coefficient of die surface had a significant impact the mould filling time, the rich coating of wound can make dry friction coefficient greatly reduce, thus makes filling speed accelerate more than 10%, is particularly useful for vehicle mould.
After testing, the abrasion loss under pre-plating piece rete Tabor CS-10 model emery wheel 1 kilogram of load of the inventive method is used to be 14 milligrams, hardness can reach Lip river formula 36 degree to 62 degree, and preservative property 0.001 inch of thickness of coating also can bear the SaltSprayTest more than 300 hours.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
