Ceramic spraying is a heat source used in some conditions. It can be used to heat the powder or filament spray material to melt, and then spray it into the surface of the processed part to form a spray Layer, mainly using processing methods to improve or change the surface properties of the workpiece.
1. Coating peeling and peeling
1. If the surface roughness is not enough or there is dust adsorption, it will reduce the adhesion of the spray coating; we need to strengthen the roughening of the workpiece surface and clean up before spraying.
2. If the workpiece contains grease, there will be grease overflow when we spray, such as ductile iron crankshaft, etc.; therefore, we need to carefully remove the grease before spraying and implement proper baking.
3. There are visible oil and water in the compressed air; minimize the oil and water in the compressed air, and repair or replace the compressed air device when necessary.
