Shaping Blow moulding Surface treatment Thermal-spray coating
Induction and flame hardening A surface-treatment record Take a medium or high carbon steel -- cheap, easily formed and machined -- and flash its surface temperature up into the austenitic phase-region, from which it is rapidly cooled from a gas or liquid jet, giving a martensitic surface layer. The result is a tough body with a hard, wear and fatigue resistant, surface skin. Both processes allow the surface of carbon steels to be hardened with minimum distortion or oxidation. In induction hardening, a high frequency (up to 50kHz) electromagnetic field induces eddy-currents in the surface of the workpiece, locally heating it; the depth of hardening depends on the frequency. In flame hardening, heat is applied instead by hightemperature gas burners, followed, as before, by rapid cooling. Physical Attributes Coating thickness 300 - 3e+003 µm Component area restricted Processing temperature 727 - 794 K Surface hardness 420 - 720 Vickers Economic Attributes Relative tooling cost low Relative equipment cost medium Labor intensity low Typical uses The processes are used to harden gear teeth, splines, crankshafts, connecting rods, camshafts, sprockets and gears, shear blades and bearing surfaces.
