Wear Performance of Low-Energy-Nitrogen-Implanted Stainless Steels in a Corroding Environment
- Albany Research Center
Wear-corrosion of 304 stainless steel and N{sub 2}{sup +} implanted 304 stainless steel has been studied using a pin-on-disk apparatus developed at the Albany Research Center. A nitriding process, utilizing low energy (3-10 KeV) N{sub 2}{sup +} implantation at high temperature (400-450 C) has been demonstrated for a variety of steels. Nitride layers up to 10 {micro}m in thickness, with hardnesses approaching 8 GPa, have been produced by this technique. The wear test apparatus allows the examination of metals and alloys in a sliding wear-corrosion environment, and uses electrochemical control to study the effects of wear alone, corrosion alone, and wear-corrosion. Pin-on-disk testing in corrosive media suggests that an improvement in wear resistance is realized without significant degradation of corrosion response.
