ショットピーニング(Shot Peening)とは、ショット(shot

ショットピーニング(Shot Peening)とは、ショット(shot:鋼製小粒子)ピーニング(Peening:ハンマーの丸みの部分で叩く)の意味で、古くは19世紀に鋼版をハンマーで叩いて強くしたことから始まり、車両の板バネ等に多く実施されました。
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。さらに表面異状層の改善や水素脆性防止にも役立ちます。
手法的には同じですが表面の付着物除去目的のショットブラスト・サンドショットとは区別する必要があります。

Steel particles (shot) (Shot Peening) shot peening and shot peening (tap on the roundness of Peening hammer part) the old began in the 19 century steel plate with a small hammer, strongly, plates of the vehicle was conducted more in the spring, etc..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. Further improvement of surface anomalies and preventing hydrogen is useful.You must to distinguish surface for debris removal blasting, sand shots and is very similar to a method.

The shot peening (Shot Peening), shot (shot: steel small particles) peening: in the sense of (Peening hit at the portion of the roundness of the hammer), from the fact that it was in ancient times strongly by hitting a steel version in the 19th century with a hammer It starts, and has been implemented in many leaf spring of the vehicle or the like.
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. And it will help to further improve the surface abnormal layer and hydrogen embrittlement prevention.
The methodological it is the same, but you must be distinct from the shot blasting sand shot of deposit removal purpose of surface.

Shot peening of Shot Peening, steel shot of Shot Peening in small particles in the Peening hit with a hammer, a rounded portion in the 19th century to the steel plate with a hammer to beat a strong came into effect, a lot of plate spring a vehicle or the like. At the heat treatment hardening, carburizing and quenching with high residual compressive stress is obtained by projecting it on a hard surface hard work hardening on the surface of the product. By the improvement of the residual compressive stress to fatigue resistance and durability.Further improvement of surface defects and helps to prevent hydrogen embrittlement layer. The method is that the same must be distinguished from the ショットブラスト・サンドショット for removing surface deposits.
