Nitriding of crankshaft
Webb16 nov. 2024 · The crankshaft is subjected to large loads and changing bending moments and torques. The common failure modes are bending fatigue fracture and journal wear. Therefore, the crankshaft material is required to have high rigidity and fatigue strength as well as good wear resistance.

WebbA modern computerised nitriding furnace Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These … WebbThe relatively low temperature of nitriding, usually in the range 480-570 °C allows fully stabilised, hardened and tempered components to be surface hardened with only minimal risk of distortion and dimensional variations enabling them in most cases to be used without further grinding or lapping.
WebbInduction hardening is a surface hardening technique which uses induction coils to provide a very rapid means of heating the metal, which is then cooled rapidly, generally using water. This creates a “case” of martensite on the surface. A carbon content of 0.3–0.6 wt% C is needed for this type of hardening.

REM (ISF – Isotropic Superfinish) Process – The ideal surface finish for metal on metal contact . Webb28 maj 2016 · Nitriding takes place in a heated container where the crankshaft is exposed to ammonia and nitrogen gas. Nitrides are formed as the gas reacts with the carbon on the surface of the steel. This results in a superior surface hardness that is more resistant to abrasion and stress-related failure.
