摘要
介绍了超音速火焰喷涂装置的结构组成和工作原理,论述了喷涂零件处理方法和应用效果。
High Velocity Oxygen Fuel Spray can make excellent carbonized ceramic-mental coat whose combination strength is more than 70MPa, cavity rate is less than 2%, hardness is more than HV1000 wear-resistance and anticorrosion is good, which can enhance the wear-resistance and anticorrosion of the metal seated ball valves, With this technology, we have developed the metal seated ball valve used in the high-temperature and high-corrosive industry and the scraper ball valve with scraper to clean the tar , which improve the metal seated ball valves＇ lifetime and application range.
