摘要:
运用能谱分析方法对3J1弹性合金固溶处理和表面处理后外观形貌中出现白斑及黑点的缺陷进行分析，并对分析结果进行试验验证，从而对3J1弹性合金固溶处理和表面处理过程的控制提出改进和建议。结果表明：固溶处理后出现的白斑是固溶处理前材料表面清洁不到位或基体缺陷从而导致氧化皮不均匀，在快速冷却过程中氧化皮爆开而暴露出的材料基体，而固溶处理后的黑点是材料表面油污、杂质等形成的碳化物。酸洗可清除固溶处理后的黑斑，但白斑却依然存在，分析表明酸洗后出现的白斑是材料局部酸洗尺寸不同导致的腐蚀坑。
Abstract:
The energy spectrum analysis methods was used to analyze the defects of white spots and black spots in the appearance of 3J1 elastic alloy after heat treatment and surface treatment, and the analysis results were verified experimentally. Thus, the improvements and suggestions were put forward for the control of heat treatment and surface treatment process of 3J1 elastic alloy. The results show that the white spots after solution treatment are uneven oxide scales caused by inadequate surface cleaning of the material before heat treatment or matrix defects, which exposes the material matrix during water quenching. The black spots after solution treatment are carbides formed by oil and impurities on the surface of the material. Pickling can remove the black spots after heat treatment, but the white spots still exist. The results of analysis show that the white spots after pickling are corrosion pits caused by different sizes of local pickling of the material.
