The principle of plasma spraying technology is to change the surface properties of the material, heat the sprayed material to a molten or semi molten state with a certain heat source, blow it into small particles, and spray it onto the surface of the substrate through island velocity airflow to form various coating processing methods. Plasma spraying not only has the same size as other spraying methods, but also has advantages such as unlimited part size, wide substrate material, small processing edge, and ordinary substrate surface spraying reinforcement.Compared with plasma spraying methods, plasma spraying technology is a relatively new thermal spraying technology with many advantages. The working environment depends on the material and size distribution of the sprayed particles, which may pose health and safety risks. The current approach is to place the work in a circle to minimize any possible risks and limit the mobility of the machine. Considering the chip current, this is a ...
Powder characteristics and parameters of supersonic spraying process:(1) Powder characteristics:At present, powder suppliers provide various types of carbon (chemical powders, powder characteristics often vary greatly due to different powder manufacturing methods. Powder characteristics include powder particle size distribution.)(2) Oxygen gas flow rate and ratioThe flow temperature and characteristics of spraying depend on the oxygen flow rate and mixing ratio. When spraying, the flow rates of oxygen and gas should be determined according to the requirements of the equipment to ensure that the smoke flow of the spray gun reaches the designed power level. In the actual production process, there are many factors that can cause fluctuations in the oxygen ratio, and the oxygen ratio is very important for determining the coating structure.In theory, complete combustion of propane requires a 5:1 ratio of oxygen to propane. (C3H8+502=4h20+3CQ2) This combustion ratio produces a neutral fla...
Due to its superior performance, supersonic spraying has been widely used in aerospace (basic standardization of engine compressor blades, bearing sleeves, etc.), steel, petrochemicals, papermaking, biomedical and other fields. It is not only used for repairing damaged parts, but also as a new type of equipment.1. Applications in the aerospace fieldAircraft landing gear generally adopts hard chrome plating technology. Ultrasonic flame spraying technology is used to reduce environmental pollution caused by chrome plating technology (HVOF), and WC Co coatings for spray painting have gradually replaced chrome plating technology in developed countries such as the West. Compared with chrome plating technology, HVOF coating technology has higher combined strength and better wear resistance. Commonly used to improve the high temperature resistance of aircraft engine blades, HVOF spray painting MCrAlY adhesive bottom layer and plasma spray surface composite coating system can effectively enh...
