INFLUENCE OF REGIMES ELECTROLYTE- -PLASMA …
plasma cementation of constructional steel 30CrMnSi and to define the related mechanical properties. As a research material, 30CrMnSi steel in initial condition and after various modes of electrolyte-plasma cementation was used. The chemical composition of the steel is as follows: 0.3% C, 0.8 – 1.1% Cr,
Electron Microscopic Analysis of 30CrMnSi Steel Surface
Using electron microscopy were investigated character of change microdiffraction pattern of fragmented substructure, the relationship between average size micrograins, which forming the diffraction pattern, and the point reflections number on the ring. Also the integrated degree of plastic deformation was assessed in the roll surface layers, made of steel 30CrMnSi during hot deformation.

Study on Microstructure and Property of Laser Melting
40Cr steel was treated by laser melting using the axis flow CO2 laser.The microstructure and property of remelting hardening layer at different paramenters was analyzed by scanning electron microscope and microhardeness sclerometer and abrasion test-machine and salt-mist test-machine.The results show that the remelting hardening layer consists of melting zone,quenching zone and heat affected
Tribological characteristics of hardened - SpringerLink
The effect of coatings deposited on cutting tools using the PVD method on the tribological characteristics of the surface layer after the finish turning of 41Cr4 and 30CrMnSi steels is considered. The tribological characteristics of the turned surfaces change substantially.
