This product exemplifies the high hardness and wear resistance of the treatment.
The material used is SKD11, with a hardness of about HRC58. The iridescent part is DLC treated and has a hardness of about Hv7000. WPC treatment is applied to increase adhesion to the substrate and further increase hardness. (*WPC treatment...A technology that modifies the surface of metal products by mixing fine particles with compressible gas and impinging them at high speed.) When the surface is modified, it becomes harder and strengthens the surface, while at the same time improving adhesion and friction/wear properties. Depending on the material, the surface will be about 1.5 times harder. Long life can be achieved by combining with DLC.
