摘要

针对小口径管道内壁因输送物质引起的损害问题，自主研制了一套管内壁丝电爆喷涂装置，可在内径40 mm以上的管件内表面进行喷涂，且可以实现爆炸槽的自动更换。在直径50 mm的油气田专用碳钢管内表面进行电爆喷涂试验，制备2Cr13涂层。对制备的2Cr13涂层的特性进行检测分析，发现涂层和基体之间形成冶金结合界面；涂层为典型的纳米晶结构；涂层硬度为320.5 HV；涂层的摩擦系数相对基体而言更低，涂层具有更好的耐磨性；涂层的自腐蚀电位高于基体，自腐蚀电流密度小于基体，具备更好的耐腐蚀性能。

Abstract

In view of the damage caused by the inner wall of small diameter pipelines due to the transport of substances

independently developed a set of pipe wall wire electro-explosive spraying device

can be sprayed on the inner surface of the pipe fittings with an inner diameter of 40 mm or more

and can achieve automatic replacement of the explosive groove. In the diameter of 50 mm oil and gas field special carbon steel pipe inner surface electro-explosive spraying test

the preparation of 2Cr13 coating. The characteristics of the prepared 2Cr13 coating were tested and analysed

and it was found that the metallurgical bonding interface was formed between the coating and the substrate; the coating was a typical nano-crystalline structure; the hardness of the coating was 320.5 HV; the coefficient of friction of the coating was lower than the substrate

and the coating had a better abrasion resistance; the coating's self-corrosion potential was higher than the substrate

and the self-corrosion current density was lower than the substrate

and it had a better corrosion resistance performance.
