Effect of nitriding on the hardness Microstructure corrosion and wear Behaviour of aisi 316ln stainless steel

Abstract

Selection of materials for engineering applications is mostly based newlineon requirements of bulk and macroscopic properties like strength ease of newlinefabrication availability cost etc However most engineering failures due to newlinefatigue corrosion etc are known to be initiated at the surface Initiation of newlinecracks defects at the surface is a life limiting factor This is because the newlinesurfaces of the components are exposed to severe thermal chemical and newlinestress conditions Methods to selectively enhance the surface properties of the newlinematerials can therefore result in significant benefits However for service newlineenvironment leading to corrosive wear and erosion apart from the selection of newlinematerial suitable surface modification procedures that can withstand various newlinetypes of stress are required newline newline
