Current Situation and Development Trend of Vacuum Electroplating Composite Coating Technology

A single surface coating cannot meet the harsh working conditions in surface engineering design, and any surface treatment has its own advantages and disadvantages, because the performance advantages of different coating materials are used to form multiple multi-layer composite coatings (including Gradient layers that are extremely gradual) are of great significance. Foreign countries have carried out research on multi-layer composite coating technology with a single-layer coating thickness of nanometers and more than 100 layers. The prepared coating has high corrosion resistance, toughness and strength, and is combined with the matrix. The strength is also good, and the surface roughness is low, which is beneficial to the machining of straight precision high-speed machining. Foreign countries have been included in the main development aspects, and it is expected that there will be new breakthroughs in the research and application of nano-scale fine coating materials. Because the composite coating technology has the functions of anti-wear, anti-oxidative corrosion at high temperature, heat insulation, etc., it can expand the application range of coated products and prolong the service life. It is a technology that will develop rapidly in the next century.
