Investigation of Wear Characteristics on Gas Nitrided AISI 304 Stainless Steel under Dry Sliding Conditions

Abstract

Stainless steel is a popular material used in various industries due to its excellent corrosion resistance, high strength, and durability. Gas nitriding has been found significantly to improve wear resistance. Chosen for this research work AISI 304 were examined and the impact of gas nitriding to 12 hrs, 24 hrs and 36 hrs were analyzed for better wear behavior. To evaluate the tribological behavior, wear tests were carried out using pin on disc tribometer. The samples were undergone with hardness tests and the microstructures were examined through scanning electron microscope The difference between the compound layer and the diffusion layer were analyzed on the microstructure. The results of untreated samples and nitride samples were compared.
