laser surface transformation hardening

基本解释

The characteristic and mechanism of laser transformation hardening , the technics of laser surface heat treatment were introduced.
主要介紹了激光相變硬化的特點及強化機理、激光表麪相變硬化工藝。
The results show that, the laser treated layer includes surface melted layer, overheating layer and transformation hardening layer.
結果表明，激光処理層分三層：熔凝層、過熱層和相變硬化層。
