AVINIT C320-MS1 MULTI-LAYER WEAR-RESISTANT COATING FOR FLAT SLIDE VALVES

摘要

A multi-layer coating placed on preliminarily nitrated surface includes layers of titanium nitride. The coating is formed of four layers each of which is formed of nano-layers. The first layer is made of nano-layers of titanium, the second of alternating nano-layers of titanium and titanium nitride, the third and the fourth layers of alternating nano-layers of titanium nitride and aluminum nitride at different ratios of thicknesses of nano-layers.
