SUMMARY
A method of controlling the gaseous nitrocarburising process parameters with the use of a control loop type
installation which is mainly composed of the hydrogen probe, the nitriding controller, the temperature controller
and the nitrocarburising furnaces is presented in this paper. The nitrocarburised experiments were performed
in an atmosphere obtained from ammonia and endogas and the cooling stage was performed in carbon dioxide.
The metalographical analyses of the nitrocarburised samples obtained in controlled nitrocarburising conditions
are reviewed. A brief description of main nitrocarburising characteristics and advantages is also realized.
Keywords
