Abstract—The possibility of increasing the wear resistance of ductile VCh500-7 iron by isothermal quenching using a new method is studied. It differs in that cooling and holding are carried out according to the water–furnace scheme, not in a molten salt and alkali, as in the current technology. An increased level of wear resistance is achieved by obtaining in the structure, along with lower bainite and graphite, 20–37% metastable residual austenite. The isothermal quenching according to the new method is environmentally friendly and more economical than that currently used.

等温淬火方式对高强度铸铁耐磨性的影响

摘要—研究了​​使用新方法通过等温淬火提高球墨铸铁VCh500-7的耐磨性的可能性。区别在于,冷却和保温是根据水-炉方案进行的,而不是像当前技术那样在熔融盐和碱中进行。通过在组织中获得较低水平的贝氏体和石墨以及20-37%的亚稳态残余奥氏体,可以提高耐磨性。根据新方法进行的等温淬火对环境友好,并且比目前使用的方法更经济。
