Flame Spraying Technology

Flame spraying technology is a form of the thermal spraying technology. Just like it’s name, it comes out like a flame when it works.

The basic characteristics of flame spraying technology are: general metal, non-metallic substrate can be sprayed, the shape and size of the substrate is usually not limited, but the holes cannot be sprayed at present; Coating materials are extensive, metal, alloy, ceramic, composite materials can be coating materials can make the surface has a variety of properties, such as corrosion resistance, wear resistance, high temperature resistance, heat insulation, etc.

Flame spraying has little influence on the substrate, little deformation of the substrate and no change in the material structure. The disadvantages of flame spraying technology: coating and substrate bonding strength is low, cannot withstand alternating load and impact load; High requirements for preparation of matrix surface; The flame spraying process is affected by many conditions and there is no effective method for testing the coating quality. Common flame spraying methods include acetylene-oxygen flame powder spraying, acetylene-oxygen flame wire spraying, etc. The equipment for acetylene – oxygen flame powder spraying is simple and suitable for field construction and maintenance.
