Chemical-thermal treatment technology for manufacturing parts of electrical equipment for automobile transport

Abstract

The state of technology and equipment for thermal and chemical-thermal treatment used for manufacturing of the main parts of starters, ignition distributors, generators has been analyzed. It is noted that the technical level of these technologies and equipment does not meet modern requirements. Technologies of carburization in solid carburizer and cyanidation in liquid medium often lead to formation of unstable parameters of diffusion layer on the surface of parts and finally to “spot” hardness and intensive wear of parts during operation.
In order to modernize the processes of cementation and cyanidation, environmentally friendly technologies of chemical-thermal treatment have been developed, which provide stable parameters of the diffusion layer, thereby contributing to the improvement of the operational characteristics of automotive transport electrical equipment products.
