1.  The Invention

 

Title: Ecologically friendly thermo-chemical treatment of of steel products.

The problem the inventor(s) wanted to solveThis device is used for stresses measurements, hardness and thickness of the diffusion layers and coatings, the occurance of flaws and determining their size, as well as detection and localization of grinding burns and the size and type of material degradation.

Description: The developed technological process named nitrooxidation AG is a modification of an earlier technology of gaseous oxynitriding, developed by IMP, consisting of the subjection of steel products to the action of an atmosphere generated from a mixture of ammonia and water vapour at temperatures within the range of 500 - 600 oC and implemented widely, especially in the case of tools made from high speed steel.

Presentation.  POSTER
Fields of application
: In the nitrooxidation AG process, effluent gases emitted to the atmosphere contain neutral components, i.e. nitrogen, water vapour and carbon dioxide.

Advantages: One of the most important features of the nitrooxidation AG process in comparison with earlier used technologies is the separation of the nitriding phase from that of oxidation in water vapour in a way which eliminates the formation of ammonia water in effluent gases which in the nitrooxidation process caused pollution of the natural environment.
