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

Abstract EN

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

Ini paper, a comparative study of polymer solution and oil quenchants on hardeniij automotive camshaft was studied.

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

Results showed obtained by polymer quenching in the surface of gray cast iron, maximum liardnBS but minimum hardness obtained by oil quenchant in the core of gray cast a* Various aspects of the organic and physico-chemical properties such as poly^ concentration, temperature exhibit a great effects on both cooling rates and quench uniformity
