[Abstract]:
Most wear composite coatings with nickel plating as a matrix, in addition, there are copper, iron, chromium, cobalt and nickel - phosphorus alloy
Most wear composite coatings with nickel plating as a matrix, in addition, there are copper, iron, chromium, cobalt and nickel - phosphorus alloy, dispersed particles are generally of high hardness materials such as silicon carbide, boron nitride, aluminum oxide, diamond and so on. Such composite coatings in the engine cylinder, wheel, grinding machine, the grinding dental needles universal application.
 
Lubrication is a major feature of composite coatings. Nickel or copper matrix metal, molybdenum disulfide, graphite, graphite fluoride, polytetrafluoroethylene (PTFE) as the composite coating dispersed particles, the friction coefficient is very low, in the application of bearings, shaft, cylinder, gear, etc. up to especially suitable for combination prone seizing of metals.
 
Ni - PTFE composite coating well on plastic, rubber mold release molding mold; zinc - silica composite coating can improve the adhesion of the coating; Ni - P - SiC composite coatings can be at high temperatures improved abrasion resistance, the model used for continuous casting; key - strokes composite coating can improve the heat resistance; Nickel - fluorescent dye composite coating improves decorative. In addition, the composite plating may obtain a conductive, antireflection property, touch activity, porosity and other functions
