Physical and Tribological Properties of Nitrided AISI 316 Stainless Steel Balls

open access: yesMATEC Web of Conferences, 2016
AISI 316 austenitic stainless steel balls (diameters 5.0 and 12.0 mm, typical hardness 250 HV0.3) and flat samples (20×20×2.0 mm) were nitrided by a pulsed glow discharge Ar/N2 plasma. Hardness of the ball surfaces was analysed using Vickers indentation.
