AbstractLaser surface hardening is a noncontact process that provides a chemically inert and clean environment as well as flexible integration with operating systems. This article provides a brief discussion on the various conventional surface-modification techniques to enhance the surface and mechanical properties of ferrous and nonferrous alloys. The

Laser surface hardening of 11% Cr ferritic stainless steel and its sensitisation behaviour
Surface & Coatings Technology, 201811% Cr ferritic stainless steel conforming to EN 1.4003 standard was surface hardened by a continuous-wave fibre laser beam. Both single-pass and multi-pass laser hardening was investigated. Different laser parameters were compared and their influence on

Study on surface grind-hardening of SKD-11 hardened steel
International Journal of Manufacturing Technology and Management, 2007In grinding SKD-11 hardened steel, the martensite phase transformation is the results of the thermo-mechanical coupled effect and the grind-hardening is highly dependent on the grinding parameters. Special attention is paid to indicating formation mechanism of dark-etching layer and the transition layer to get the desirable hardened surface.

SURFACE HARDENED NAVAL MARINE GEARS WITH REFERENCE TO ALTERNATIVE MEANS OF SURFACE HARDENING
Naval Engineers Journal, 1984ABSTRACTIt has become common practice in naval marine gear units of European manufacture to take advantage of the greater load carrying capacity resulting from a surface hardening process. The surface hardening processes open to the gear designer are many and varied, and each has advantages and disadvantages.This paper examines the three principal ...

Low-temperature surface hardening of stainless steel
AM&P Technical Articles, 2013Abstract Low-temperature surface hardening of stainless steel by means of gaseous processing provides a high degree of tailorability of the hard surface case without affecting corrosion resistance. This article covers the fundamental and technological aspects of the process and examines the effect of different LTSH treatments on 304 and ...

1. The considerable technical and economic advantages of surface hardening after high-frequency heating, giving better service performance, labor savings during manufacture, lower heat treating cost and also offering the possibility of complex automation of the production cycle, may be used to fullest extent only if for the components in question a ...
