Abstract
Hardening Constant Velocity joint increases hardness near the surface and the surface improves fatigue life. Although case depth and chemical composition are same, the prior structure of induction hardened Constant Velocity Joint affects the fatigue strength and life during hardening. Therefore torsional fatigue tests of specimens from vaere conducted on induction hardened automotive Constant Velocity joint with various case depths and lrious prior structures, which are obtained by nomalizing, spheriodized annealing and tempering after quenching, woads applied in order to evaluate the relation between prior structure and fatigue strength.
Keywords
