The study of behavior of graphite phase in the laser hardening layer of gray iron;
珠光體灰口鑄鐵激光硬化層中石墨相行為研究
After proper conditioning and laser parameters were selected,laser hardening was performed on LY12.
此外，還系統(tǒng)地研究了工藝參數(shù)對(duì)硬化區(qū)尺寸的影響，工藝參數(shù)與硬化區(qū)顯微硬度的關(guān)系，激光硬化區(qū)的顯微組織變化及化學(xué)成分的能譜分析等。
The effects of laser hardening on the structure and wearability of a normalized and an austempered ductile iron were investigated.
結(jié)果顯示對(duì)于等溫淬火球鐵,激光硬化層中馬氏體片的尺寸與基體奧氏體—貝氏體中的鐵索體板條尺寸相近。
