熱処理(焼入れ・浸炭焼入れ)された製品表面に硬い硬球を投射することで表

熱処理(焼入れ・浸炭焼入れ)された製品表面に硬い硬球を投射することで表面が加工硬化し高い残留圧縮応力が得られます。
残留圧縮応力の向上により耐久性や耐疲労破壊性が向上する。

And then hardened in projecting a stiff Hardball to the product surface treatment (put the hardened and case-hardened), will have a higher residual compressive stress.Improvement of residual compressive stress improves durability and fatigue fracture.

Surface machining hardened high residual compressive stress is obtained by projecting the hard hardball to heat treatment (quenching and carburizing and quenching) has been the product surface.
Improvement of residual compressive stress by improving the durability and resistance to fatigue fracture resistance.

Carburized quenching heat treatment, which is a high residual compressive stress is obtained by projecting it hard hard work hardening in the surface of the product surface. By the improvement of the residual compressive stress to fatigue resistance and durability.
