特材零件除油工艺参数的优化研究

特材零件除油作为表面处理重要而又关键的环节，直接影响表面膜层的形 成和性能。本文重点论述了除油工艺的重要性和特材零件油污的来源，并有针对性的对 汽油浸泡、表面活性剂超声清洗、阴极电解除油等除油方法进行试验研究，优化各工序 工艺参数。除油效果采用水润法进行检验，检验结果表明：试验确定的除油工艺方法合 理，效果明显，去除了特材基体表面油污，露出了活泼的特材基体，为特材表面获得优 良的表面处理膜层打下了基础。

Optimization Research of Special Material Parts Degreasing Technological Parameters

Special material parts degreasing technique is an important and key link tache, and directly influences the surface film and its performance. This paper emphatically discusses the importance of degreasing technique and the source of oil on the special material parts. To the point, the degreasing methods including gasoline soaking, surfactant ultrasonic washing and cathode electrolysis washing are experimentally studied, and the technological parameters of these methods are optimized in the paper. The effect of degreasing is inspected using hydra law, and the experimental results show that the techniques determined by the tests are reasonable, and the effect is obvious. The techniques can remove the dirt on the surface of special material matrix. The active special material matrix can reveal using the techniques. The study lays the foundation for obtaining excellent surface treatment coating.
