本文采用热线法研究了氯型、硫型、二硫代磷酸锌型以及硫氯混合型极压剂与铁表面的化学反应。铁的腐蚀速率服从抛物线规律或立方规律。抛物线规律可以用腐蚀扩散机制来解释。为了解释立方定律，假设了阻挡膜的缓蚀作用。通过对反应产物的X射线分析，揭示了腐蚀过程的复杂性。二异丁基二硫代磷酸锌在腐蚀过程中表现出特有的行为，表现出缓蚀作用。对于二元添加剂体系，硫和氯化合物在铁上的联合反应在本研究范围内不能得到满意的支持。一些有趣的考虑给出了C.
The work to be described in this paper, is a study of chemical reaction between iron surfaces and various representative extreme pressure (EP) agents, such as chlorine type, sulfur type, Zn-dithiophosphate type, and the mixture of sulfur and chlorine type EP agents, by using the hot wire method. It has been observed that the corrosion rate of iron follows the parabolic law or the cubic law. The parabolic law can be explained by the diffusion mechanism of corrosion. In order to explain the cubic law, the corrosion retarding action of a barrier film has been assumed. From the X-ray analysis of reaction products, the complexity of corrosion process has been revealed. Zinc-diisobutyldithiophosphate has shown the characteristic behavior in the corrosion process, showing retardation against the corrosion. With a binary additives system, the joint reaction of sulfur and chlorine compounds on iron could not be satisfactorily supported in the scope of this study. Some interesting considerations are given for the c...
