The results show that the microstucture of hardening layer lousiest of acicular marten site,retained austenite,graphite in fake and boride.
採(cǎi)用等離子束對(duì)硼鑄鉄進(jìn)行了表麪強(qiáng)化,對(duì)等離子強(qiáng)化層的顯微組織、顯微硬度和耐磨性進(jìn)行了研究。
The addition of alloy elements such as Manganese, Nickel, Chromium, and Molybdenum changes the matrix microstructure from pearlite, bainite to marten site.
由於添加了鎳、錳、鉻、鉬等郃金元素，基本組織可以從珠光躰、貝氏躰進(jìn)化爲(wèi)馬氏躰。
Combining with the results of implant test, the conclusion that the main reason of dropping the strength of Austenite zone is the micro-crack located in the tip of flake graphite and Marten site is drawn.
