Thermochemical surface engineering using plasma nitriding can improve the properties and performance of gears made of steels and titanium alloys.
Among thermochemical methods, the processes of plasma nitriding and gas nitriding have progressed in the industry to increase gear performance.
The surface properties of gear steels can be improved by thermochemical and mechanical treatments.
Plasma/ion nitriding meets demanding gear applications by offering increased load capacity of gears and increased fatigue strength of components as well as less complicated masking treatments.
Various thermal operations can be used to prevent distortion induced from any stage in the manufacturing process, whether it’s before or after heat treatment.
Comparing wear resistance of nitrided and carburized cases formed on the same steel can help designers choose which method to use.
