Plasma nitriding in a glow discharge is a relatively new and extremely promising method of steel surface hardening. Ion-nitrided samples show a tendency to a longer lifespan during severe wear and cyclic loading compared to the traditional gas nitrid

Among metallic biomaterials, AISI 316L has the cheapest price yet but the lowest mechanical properties and it is prone to corrosion. Bone plate failure is often triggered by dynamics load, crevice or pitting corrosion, or a combination of fatigue and
