Dry Sliding Wear Behavior of Austenitic Stainless Steel Material by Gas Nitriding Process

In industries, components must operate under extreme conditions such as high load, speed, temperature and chemical environment. Materials are selected according to commercial availability, cost their properties strength, hardness, etc. AISI 904L is a high-alloy stainless steel with low carbon content, poor surface hardness wear characteristics. Many engineering failures caused by fatigue, corrosion, resistance, begins at the level. This causes cracks in surface, reducing material’s life. The surfaces of materials were subjected severe thermal, chemical, shock loads. for this work gas nitriding process processed 3 different time parameters 12 hours, 18 hours 24 respectively named GN1, GN2 GN3. treatments done constant 650°C. Gas nitriding, comparison other processes plasma liquid provides good dimensional stability, reduced deformation, uniform case depth regardless size shape specimen. To analyze properties, pin on disc machine used. Finally, metallographic studies performed scanning electron microscopy.
