Abstract

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.
