Developments of P/M parts and materials for high performance engines

Akira Fujiki

Research output: Contribution to journalArticlepeer-review


New P/M parts and materials are developed for high performance engines which show high power and torque with low emission and low fuel consumption. As for P/M parts, sinter-joined sprocket is explained. In this development, materials selection and design are referred. Also new test method for torsion fatigue test is explained. Non destructive analytical technique is developed to evaluate joint area by ultrasonic. As for P/M materials, development of P/M molybdenum steel base anti-wear materials are explained. These were developed for engine cam-followers and valve seat inserts. And also new valve/valve seat wear test apparatus are developed.
