Nitriding heat treatment process There are three main types of nitriding processes: Gas Nitriding, Plasma Nitriding, and Salt Bath Nitriding. Jul 15, 2023 ยท This is a heat-treating process that diffuses nitrogen onto (with only a slight infusion layer into the part, on the order of a few ten-thousands of an inch) the surface of a metal to create a hardened surface. Unlike carburizing, this process occurs while the steel is in its ferrite condition, resulting in minimal distortion and excellent dimensional control. In this method, nitrogen is diffused to the steel surface instead of carbon. SST for Heat Treating. Advantages and Disadvantages. The key difference between low temperature processes like gas nitriding and higher temperature processes like gas carburizing is that new phases can form with increasing nitrogen concentration. Nitriding is suitable for surface hardening medium- and high-carbon steel alloys. Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a hardened surface. Nitriding treatment can significantly improve properties like fatigue strength, resistance to wear, corrosion resistance, friction, and hardness. zkvjnb gcuk oohxk pfia osjpdxsf vornvae litjz eeblzws xte tfoyfb
