Many factors affect the quality of the thermal spray coating, spray coating and melt the categories. Practice has proved that as long as the strict implementation of process rules, pay attention to the following technical factors, the coating quality can be guaranteed. (1) of the workpiece surface preparation ① undercut undercut means to provide a space to accommodate the thermal sprayed layer on the base material or part or worn out vehicle size. When the shaft is not usually wear, but to save labor and materials can be divided into steps undercut, shaft head indeed manner. ② clear up that remove oil, rust, paint, so that the surface is clean. CTC degreasing better, not on the part of residual metal spraying prescription next film, but harmful carbon tetrachloride, the operation should be cautious. Suitable for cleaning up oil flame baked porous castings, where oxygen-acetylene flame baking oil most commonly used. Sometimes Shunde net for degreasing metal spraying to need repeated the 20th century, the development of thermal spray technology is very fast metal spraying, and to promote the use quickly. To the 20th century, Jiangsu metal spraying, plasma spraying is still dominant. It is worth noting that the high-speed flame spraying (HVOF) rapid development, will occupy 25% of the market share, ranking second. Arc spraying technology, because the economy is good, the coating layer superior performance than flame spraying, flame spraying technology will partially replace rose to third place.
