Study the effect of polymer solution and oil quenchants on hardening automotive camshaft

Abstract EN

The type of quenchant is directly affect the cooling rate of a quenched part.

In this paper, a comparative study of polymer solution and oil quenchants on hardening automotive camshaft was studied.

Cooling curves and microstructure in cylindrical samples of automotive camshaft (grey cast iron) have been performed to investigate the effects of quenching media, polymer concentration and temperature of oil quenchant on the quenching behavior of automotive camshaft.

Results showed that maximum hardness obtained by polymer quenching in the surface of gray cast iron, but minimum hardness obtained by oil quenchant in the core of gray cast iron.

Various aspects of the organic and physico-chemical properties such as polymer concentration, temperature exhibit a great effects on both cooling rates and quench uniformity.
