Investigation of durability of VKS-7 and VKS-10 steels after vacuum carbonization and vacuum carbonitriding
Engineering Education # 05, May 2013
DOI: 10.7463/0513.0568124
Development of new technologies of thermal and thermochemical treatment, based on the activation of cementation processes and which could provide volume and surface finely-divided or nanostructured state of constructional materials appeared to be a very powerful method to increase the durability of critical machine elements. Results of estimating the durability and micro-hardness of VKS -7 and VKS-10 steels were presented in this article after complex processing which consisted of two stages: 1 – preliminary plastic deformation by means of warm shortening and 2- plasma nitration or vacuum carbonization. Analysis of the relation between hardness and durability was carried out.
