The results show that the microstucture of hardening layer lousiest of acicular marten site,retained austenite,graphite in fake and boride.
采用等离子束对硼铸铁进行了表面强化,对等离子强化层的显微组织、显微硬度和耐磨性进行了研究。
The addition of alloy elements such as Manganese, Nickel, Chromium, and Molybdenum changes the matrix microstructure from pearlite, bainite to marten site.
由于添加了镍、锰、铬、钼等合金元素，基本组织可以从珠光体、贝氏体进化为马氏体。
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.
结合插销试验结果提出了马氏体相变过程中，在片状石墨尖端及马氏体组织中造成的微裂纹是奥氏体区强度下降并进而在外力作用下断裂的主要原因。
