Constant velocity universal joint component and manufacturing method thereof |
摘要 |
In a constant velocity universal joint component and a manufacturing method thereof capable of achieving increased strength without significant procedural changes, and that can contribute to size reduction and weight reduction, a sharp-angled portion 15 is formed by machining after cold plastic working is applied. A carburization process is then performed in which surface carbon concentration of 0.45 mass % to less than 0.60 mass % is obtained. Quenching is then performed. High-frequency induction hardening is subsequently performed. |
