Study On The Effect Of Nitriding Temperature Towards Wear Resistance Of Duplex Stainless Steel

This report basically discusses the research or review done and basic understanding of the chosen topic, which is Study On The Effeet Of Nitriding Temperature Towards Wear Resistance Of Duplex Stainless Steel. In industry, duplex stainless steel has been used due to good corrosion resistance, high fatigue resistance, high wear resistance and high mechanical strength. It is also brittle. The nitriding process has been chosen as the heat treatment process that can enhance the mechanical properties of the duplex stainless steel. The sample undergoes constant 6 hour of nitriding process in the tube furnace with different temperature which are I I 00°C, 1050°C and I 000°C. High temperature gas nitriding (HTGN) has been used in this project. All the parameters for the nitriding process such as temperature and time must be setup on the horizontal tube furnace. Optical microscopy, as well as glancing angle X-Ray diffraction (XRD) has been used to study the nitrided surfaces. For wear test, pin on disc method has been chosen as the method to analyze the wear resistance of each sample. The result from the wear test is measured by determining the weight loss as function of sliding distance. In order to perform this project, all the steps for the experimental work must be understood. The nitriding process is the key factor for the project. It is to determine whether the nitriding temperature can affect the wear resistance of the stainless steel. The weight losses of the sample are increased in the wear test as the temperature of nitriding for the sample increase. The nitrogen diffuses into the steel better when the temperature is high. It improves the wear resistance of the duplex stainless steel
