Description

Technical Field

[0001] This utility model relates to the field of workpiece coating equipment, specifically a workpiece coating thermal barrier protection component. Background Technology

[0002] Thermal barrier coating is a surface treatment process. Thermal barrier coatings (TBCs) are ceramic coatings applied to the surface of metal workpieces. Their main purpose is to provide thermal insulation, reduce the temperature of metal parts in high-temperature environments, and protect the metal substrate. The coating process begins with cleaning the workpiece surface to remove impurities such as oil, rust, and scale, ensuring good adhesion between the coating and the substrate. Common cleaning methods include chemical cleaning (such as using organic solvents and acid pickling) and physical cleaning (such as sandblasting). Sandblasting can roughen the workpiece surface, increasing the contact area between the coating and the substrate.

[0003] Coating material selection; In the plasma spraying process, coating material powder is fed into a high-temperature, high-speed plasma jet. The powder is heated to a molten or semi-molten state and then sprayed onto the workpiece surface, where it quickly solidifies to form a coating. Plasma spraying can achieve high coating quality, and the coating thickness and porosity can be adjusted through process parameters.

[0004] During the coating process, the high-temperature jet sprayed from the tip of the spray gun impacts the surface of the workpiece. Some of the high-temperature particles are prone to rebound and bounce onto the workers' clothing, which can easily burn their work clothes and skin, posing a hazard to the personal safety of the operators.
