Laser surface hardening: a review
International Journal of Surface Science and Engineering, 2011Laser surface hardening (LSH) is one of the most widely used surface hardening process which can be applied to almost the whole range of metallic materials in today’s applications. Laser beam is focused to the localised region for hardening the required portion of the material. High intensity laser radiation is involved for heating the surface of steel

Mechanical components often require surface treatments to meet application demands. This chapter describes several surface hardening treatments for steel and their effect on microstructure, composition, and properties. It discusses flame hardening, induction heating, carburizing, nitriding, carbonitriding, and nitrocarburizing.

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 ...

A Novel Heat Treatment Process for Surface Hardening of Steel: Metal Melt Surface Hardening
Metallurgical and Materials Transactions A, 2017A novel heat treatment process for surface hardening of steel has been demonstrated and named as “metal melt surface hardening (MMSH).” A surface layer with a thickness of about 400 μm and a hardness of about 700 HV has been achieved by ejecting AISI 304 stainless steel melt at a temperature of about 1783 K (1510 °C) onto the 40Cr steel surface.
