Fracture Analysis for Pitman Shaft of Automotive Steering Gear

Abstract:

The fractographic appearance, microstructure, chemical elements and hardness of the pitman shaft of automotive steering gear were analyzed. The fracture is induced by improper heat treatment and non-taking anti-carburization measures on thread part. Some feasible measures, including copperizing, coating anti-carburization paint and keeping localized manufacture allowance, were proposed for preventing the occurrence of similar fractures.
