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.

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

Hardening the surface of austenitic steels by strain hardening
Metal Science and Heat Treatment, 19711. The carrying capacity in terms of permissible stress (σ0, 2) of steels Kh18N10T and Kh21N5AG7 under conditions of uniaxial static tension increases 50% down to −253° as the result of surface hardening. 2. For hardened steels Kh18N10T and Kh21N5AG7 σ b n /σn > 1 and σ b n /σ0.2 > 1 with Kt=3.0 in the range of 20 to −253° C. 3.

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 ...

Surface hardening of case hardened steel by rolling
Metal Science and Heat Treatment, 19651. Rolling of case hardened quenched steel produces an additionally hardened layer as thick as 1 mm. At the same time, the hardness increases by 100 HV units. 2. The effect of rolling depends on the type of steel, the preliminary heat treatment, and the value of the contact stress. 3.
