The hydraulic supports used in the coal mining industry, like other hydraulic supports, require a smooth surface and wear and corrosion resistance. The traditional treatment process used is hard chrome plating.With the increasingly stringent requirements for the use of hexavalent chromium under environmental protection laws, the industry is seeking more environmentally friendly and economical alternatives.
Advantages compared to hard chrome plating process
1.Thicker and stronger metallurgical bonding than hard chrome coating, reduced risk of porosity and cracking, and environmentally friendly process;
2.Excellent combination of wear resistance and corrosion resistance.
3.Excellent welding performance and outstanding machining performance.
Excellent wear and corrosion resistance
wear | corrosion |
ASTM G65-16 | Salt spray test ISO 9227 |
60-65 mm3 | 1000+hours |
1.The test sample is laser melted CMS1401 powder on a steel substrate, with a coating thickness of about 0.5mm and a dilution rate of about 9%;
2.The corrosion resistance level is based on ISO 10289;
3.After 1000 hours of salt spray testing, the surface is shiny and free of corrosion.
good high-temperture hardness
* The test sample is laser melted CMS1401 powder on a steel substrate, with a dilution rate of about 5%.
