The invention has stable process, low cost and no pollution.
Description
The present invention relates to the electroplating technology field, a kind of composite depositing process that obtains the wear resistant friction reducing layer promptly is provided.
At present, some friction means of industrial extensive application are as cylinder sleeve/piston ring, valves etc. are usually big because of frictional coefficient, low and the very fast inefficacy of wear resistance causes the crack to leak, though there are some people to do a lot of research work for addressing the above problem, more as the eighties initial stage metal institute and the Liaohe Oil Field on dissecting U.S. Gray company product basis, developed with the Co-Cr-W bead-welding technology and produced gate valve (valve plate and valve seat) in the thick oil thermal production well mouth device, but still exist Co-Cr-W and join pair and do not possess self-lubricating property, friction sealed antifraying property is not ideal enough, frictional coefficient is big and manufacturing procedure is complicated, shortcomings such as production cost height.
The purpose of this invention is to provide a kind of frictional coefficient, raising wear resistance of can reducing to reduce the friction pair wearing and tearing, the composite depositing process of prolongation workpiece life-span, reduction workpiece cost.
Particulate matter is joined in the plating bath, with the method for electroless plating or plating (comprising brush plating) on matrix, deposit simultaneously metal with second mutually the technology of the composite deposite of particulate be called compound plating.
Principal character of the present invention is to adopt composite plating process to add the Ni-P/ graphite-SiC or the Ni-P/SiC-graphite coating of SiC and graphite formation quaternary system simultaneously in the Ni-P matrix, reaches the wear resistant friction reducing purpose.Sheet graphite can form the little antifriction film of shearing resistance between surface of friction, good lubrication is not only arranged, and can also not use 300-400 ℃ of temperature.But metallic matrix advances the soft particle of graphite hardness is reduced because of compound, thereby influences cladding wearability and work-ing life.The Ni-P base material that the present invention selects for use is after heat treatment because of separating out Ni
3P can make its intensity increase.In addition, thus can also adjust phosphorus content by technology changes the influence of graphite to intensity.Because graphite is good conductor, occurs coating dendrite easily and fly long phenomenon in the plating process, the present invention is except the control plating technology, and an amount of adding SIC particle has not only suppressed dendrite and flown length, also can reduce the defective that hole occurs.
In the coating compound advance the SiC solid particles after because its can carry load and to the barrier effect of plow, the wear resistance of raising coating that can be by a relatively large margin.Moreover, because chimeric the controlling that the Ni-P matrix can be firm with solid particles so can make it bear and transmit shear-type load, also is of value to the improvement of wear resistance.
