摘要:
DT4C壳体在镀锌后表面出现白斑、黑点等缺陷，利用光学显微镜、扫描电镜以及X射线能谱对表面缺陷进行了分析。结果表明，壳体在镀锌前的氢气保护热处理过程中表面形成富含MnO、SiO2、Al2O3等氧化物的薄层，表面薄层的存在是造成壳体镀锌后表面缺陷的根本原因。在此基础上提出了相应控制措施。
Abstract:
Defects such as white fleck and black spot often appear on the surface of DT4C shell after galvanizing. Optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were employed to analysis the surface defects. The results showed that the thin layer containing MnO, SiO2 and Al2O3 was formed in the process of hydrogen protective heat treatment before galvanizing, which was the fundamental reason for the appearance of surface defects. Some improvement measures were put forward based on the analysis in order to solve the problem.
