The results show that the microstucture of hardening layer lousiest of acicular marten site,retained austenite,graphite in fake and boride.
采用等離子束對硼鑄鐵進行了表面強化,對等離子強化層的顯微組織、顯微硬度和耐磨性進行了研究。
The addition of alloy elements such as Manganese, Nickel, Chromium, and Molybdenum changes the matrix microstructure from pearlite, bainite to marten site.
由于添加了鎳、錳、鉻、鉬等合金元素，基本組織可以從珠光體、貝氏體進化為馬氏體。
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.
結(jié)合插銷試驗結(jié)果提出了馬氏體相變過程中，在片狀石墨尖端及馬氏體組織中造成的微裂紋是奧氏體區(qū)強度下降并進而在外力作用下斷裂的主要原因。
