摘要 |
Wear-resistant edge layer for titanium and its alloys which can be subjected to high loads and has a low coefficient of friction. The wear-resistant edge layer includes a hard amorphous carbon layer, an intermediate layer, and a laser gas alloyed layer. The wear-resistant edge layer may include a 200 to 400 nm thick hard amorphous carbon layer, a 50 to 200 nm thick intermediate layer, and a 0.3 to 2.0 mm thick laser gas alloyed layer. The laser gas alloyed layer may include precipitated titanium nitride needles and have a hardness between 600 HV0.1 and 1400 HV0.1. Process for producing a wear resistant edge layer on a substrate. The process includes forming a laser gas alloyed layer by melting a surface of a substrate, applying an intermediate layer by Laser-Arc, and depositing a hard amorphous carbon layer on the intermediate layer by Laser-Arc.
