Plasma and Vacuum Technology

• Less treatment time. 33- 50% of other nitriding methods
• Low distortion and negligible dimensional changes
• Possibility of production of desired surface phases
• Homogenous treatment of parts with complex geometry
• Environmentally friendly

Plasma Nitriding, also referred to as ion nitriding, is a thermochemical treatment that improves the wear, corrosion resistance and fatigue properties of the product being nitrided. The process was developed in the early 1930’s as an alternative to the gas nitriding. It involves diffusion of nitrogen atoms into the metal surface in presence of a plasma environment. The plasma nitriding apparatus consists of a vacuum chamber which is connected to anode and a cathode, where the parts are placed.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
