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,
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.
30CrMnSi forging steel round bars factory Price: 30CrMnSi forging steel round bars factory Price also can be called as alloy structural steel. Alloy steel means this …
Abstract: This work is devoted to research of 30CrMnSiA steel structurally modified surface layers and study of electrolyte-plasma treatment parameters influence on changing peculiarities of structural-phase state and also the increase of constructional 30CrMnSi steel operating ability.
Abstract. Abstract – The phase composition and the defect substructure of preliminary quenched 30CrMnSi steel treated by electron beam were examined us-ing metallography, scanning and transmission elec-tron diffraction microscopy.

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
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.
