Plasma Nitriding System
It is possible to make a plasma nitriding device with any dimensions and with the ability to perform nitrogen-carborizing and supplementary oxidation processes in Pars Plasmapazhouh Co. Plasma nitrogen generators are divided into two main categories: cold-wall and hot-wall.
In cold wall devices, the heating of the parts is done only by the plasma generated in the vacuum chamber (ion bombardment) (the vacuum chamber wall is hydrogen); Whereas in hot wall devices, the heating of the parts is done both by the plasma generated inside the vacuum chamber and by the heating elements installed on the chamber. Cold wall fixtures are usually cheaper and easier to maintain. Nevertheless, due to the following advantages, the use of hot wall devices is recommended:
- Very good temperature uniformity (unity) inside the vacuum chamber;
- Possibility of nitriding of parts with different dimensions and shapes in one furnace charge;
- The possibility of creating low-energy plasma and reducing the effects of phenomena such as hollow paper and sharp edges.
Hot wall and cold wall furnaces with different dimensions are made in Plasmapazhouh Pars Company and it is possible to make both types of furnaces for the customer.
