Midwest Thermal-Vac's experience in Plasma Nitriding covers the last 29 years. With the most technically advanced, computer controlled equipment available today to consistently produce controlled product. Midwest Thermal-Vac will virtually eliminate part distortion or size change while providing these Metallurgical advantages:
Pre hardened steels or alloy steels can be beneficially treated with plasma nitriding (or in other words ion nitriding). Plasma nitriding advantage is related to the close control of the nitrided microstructure, allowing nitriding with or without compound layer formation. Not only the performance of metal parts gets enhanced but working lifespan gets boosted. So does the strain limit, and the fatigue strength of the metals being treated.
Metallurgically versatile, the process provides excellent dimensional control and retention of surface finish. Ion nitriding can be conducted at temperatures lower than those conventionally employed. Control of white-layer composition and thickness enhances fatigue properties. The span of ion-nitriding applications includes conventional ammonia- gas nitriding, short-cycle nitriding in salt bath or gas, and the nitriding of stainless steels.
Plasma nitriding lends itself to total process automation, ensuring repetitive metallurgical results. The absence of pollution and insignificant gas consumption are important economic and public policy factors. Moreover, selective nitriding accomplished by simple masking techniques may yield significant economies.

A plasma nitrided part is usually ready for use. It calls for no machining, or polishing or any other post-nitriding operations. The process is user-friendly, saves energy since it works fastest, and causes little or no distortion. This process was invented by Dr. Bernhardt Berghaus of Germany and was acquired by Klockner group and popularized all over the world in late 1960s.
