Cold surface hardening

CIRP Annals - Manufacturing Technology, 2008
Abstract Cold surface hardening merges the properties of specially heat-treated high-alloyed steels with structural changes induced by mechanical processes such as deep rolling. Compared to conventional transformation-induced plasticity- (TRIP-) steels these materials show noticeably better machinability because the generated austenitic structure is ...

Investigation into the efficiency of a fiber laser in surface hardening of ICD-5 tool steel

Optics and Laser Technology, 2018
Surface transformation hardening is a vital final step in the manufacture of stamping and forming dies. An important requirement for the hardening process is minimizing the injection of heat into the precision machined component.

Multi-objective optimization of high power diode laser surface hardening process of AISI 410 by means of RSM and desirability approach

Optik (Stuttgart), 2020
In this research, laser surface hardening of AISI 410 was carried out by a high power diode laser based on Response Surface Method (RSM). Laser power, scanning speed, and focal plane position were evaluated as input process changeable while geometry ...

Surface hardening of steels by plasma hardening

Metal Science and Heat Treatment, 1983
1. Plasma hardening of steels provides hardened layers which in hardness, thickness, and wear resistance meet the requirements for hardened surfaces of many parts of various types of machines. 2. From the results of production and testing under service conditions of lots of hydraulic motor stators and troughs of conveyers it was ...
