在箔片试验基础上提出了中高温热处理盐浴用盐脱碳强度的概念,并给出了相应的定量计算公式,讨论了盐中主要杂质的作用,通过计算初步澄清了盐浴中一些物质的特性,并采用X射线衍射和扫描电镜等方法,对试样表面所形成的膜的成分和结构进行了分析。本文所获得的结论对于盐的生产、选用和校正剂配方设计均具有指导意义。 On the basis of the foil test, the concept of decarburization strength of salts for salt bath at medium and high temperature was put forward, and the corresponding quantitative formula was given. The effects of the main impurities in the salt were discussed. The preliminary clarification of some substances The composition and structure of the film formed on the surface of the sample were analyzed by X-ray diffraction and scanning electron microscopy. The conclusions obtained in this paper are instructive for salt production, selection and calibration formulation design.
