MODIFYING THE PROPERIES OF THE INCONEL 625 NICKEL ALLOY BY GLOW DISCHARGE ASSISTED NITRIDING
Journal Title: Tribologia - Year 2009, Vol 225, Issue 3
Abstract
The nickel alloys of the Inconel type (containing above 15wt% of chromium), used in many industrial applications, including the manufacture of aircraft, chemistry, power generation, and material processing, have advantageous mechanical properties, high plasticity and good corrosion resistance, but their frictional wear resistance is poor. This drawback can be obviated by subjecting the alloys to surface treatments. The paper describes the structure and properties of nitrided layers produced on the Inconel 625 nickel alloy (20wt.%Cr, 10wt.%Mo, 5wt%Fe, 1wt%Co, balance-Ni). It was found that the diffusive chromium nitride layers produced on the alloy surface improve the hardness, frictional wear resistance, and fatigue strength of the alloy.<br/><br/>
