IP (ION PLATING), ion hair color, is one of the ways for PVD dying. PVD represents physical vapour deposition, whose principle is under vacuum circumstance to the low voltage of arc discharge and large current to form a flood tide gas discharge and ionized target materials to shape a solid layer of a colorful layer on the titanium. IP ion hair color is one nontoxic way for environmental protection treatment in nano, which meanwhile has the high hardness, high wear resistance (low friction coefficient), good corrosion resistance, chemical stability, long-term nature of color, and colorful and other advantages.
