Preparation technology adds kollag particulate in the plating solution, carries out composite plating or chemical plating acquisition anti-friction wear-resistant coating.The material of the kollag used in its coating is MoS
2, graphite and polytetrafluoroethylene (PTFE) etc.
There is following defect in existing anti-friction wear-resistant coating and technique: the hardness of kollag particulate is lower, therefore lubricant particle joins in coating, reduce the integral hardness of hard coating, thus reduce the bearing capacity of hard coating, anti-friction wear-resistant effect is undesirable.
Summary of the invention
Not enough for prior art, technical problem to be solved by this invention is to provide a kind of anti-friction wear-resistant coating and preparation technology thereof, and its coating is interlocked by lubrication antifriction layer and hard coating and formed, and while ensureing coating friction-reducing performance, improves coating bearing capacity.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of anti-friction wear-resistant coating, described coating comprises lubrication antifriction layer and hard coating, and described lubrication antifriction layer and hard coating are interspersed.
Described lubrication antifriction layer is ware reducing coating layer or the dry lubricant of Ag-graphite.
Described hard coating is carbide alloy coating.
A preparation technology for anti-friction wear-resistant coating, described preparation technology comprises the following steps:
A), first hard coating is electroplate with on the surface at hard substrate;
B), then hard coating on the surface Electrolyzed Processing have texturing micropore;
C), finally in texturing micropore, lubrication antifriction layer is filled with.
Wherein, described step B) in be the texturing template adopting card punch to get the micro-pore diameter of needs, micropore spacing and arrangement on PVC tape; Again texturing template is adhered on hard coating, carry out Electrolyzed Processing, obtain the texturing micropore corresponding to the micropore on adhesive tape on the surface at hard coating.
Described step C) in adopt that composition is silver nitrate by chemical plating in texturing micropore, the plating solution compound of sodium thiosulfate, sodium hydrogensulfite, sodium acetate, thiosemicarbazide, graphite is plated to antifriction silver coating, form lubrication antifriction layer.
Or described step C) in be the coating that molybdenum bisuphide and phenoxy polyol resin mixed grinding are screened into that granularity is the dry lubricant of 1-5 μm by composition, the coating of uniform for agitation grinding dry lubricant is filled in texturing micropore, is finally heating and curing and forms lubrication antifriction layer.
The present invention compared with prior art, have the following advantages: coating is interlocked by lubrication antifriction layer and hard coating to form, its hard coating plays and supports and wear-resisting effect, lubrication antifriction layer plays the effect of antifriction, while ensureing coating friction-reducing performance, improve coating bearing capacity, anti-friction wear-resistant is effective.
