电弧喷涂

• In the aspect of thermal spraying processes the main techniques applied to water wall tubes include flame spray , arc spraying , plasma spray and high velocity oxy - fuel spray ( hvof ) . flame spray possesses the characteristics of simple equipment , easy of use and low operating cost , but the coating adhesive strength is low , and porosity and oxidation is high
  在喷涂工艺方面，制备管道涂层的方法主要有火焰喷涂、电弧喷涂、等离子喷涂、超音速火焰喷涂等。火焰喷涂具有设备简单、使用方便、操作成本低的特点，但它的涂层结合强度低，气孔率及氧化物含量高。
