Analysis of the basic process of tungsten carbide spraying
Abstract: The basic process of tungsten carbide spraying includes substrate surface pretreatment, spraying, surface heat treatment, coating sealing treatment and coating surface treatment.
Keywords: Tungsten Carbide Spraying
woco is an enterprise mainly engaged in the research and application of tungsten carbide spraying surface treatment technology.
Come, today I will bring you the basic process sharing of tungsten carbide spraying.
The basic process of tungsten carbide spraying includes substrate surface pretreatment, spraying, surface heat treatment, coating sealing treatment and coating surface treatment.
(1) Substrate surface pretreatment: After selecting the spraying method, select the pretreatment process of degreasing, rust removal and surface roughness.
(2) Spraying: When spraying tungsten carbide, reasonable process parameters should be determined to control the spraying quality.
Including: injection heat source conditions, that is, the mixing ratio of fuel and oxygen;
(3) Material conveying, that is, the type, speed, flow rate, conveying position and angle of the conveying gas;
(4) Tungsten carbide spray materials, including material composition, physical properties, powder shape, particle size, wire or rod diameter, etc.
Four basic components, substrate temperature, performance and surface treatment methods;
Five spraying operations, including the distance between the spray gun and the machine, the speed of the spray gun or machine parts, the angle between the spray gun and the machine parts, and the spraying of gaseous media.
Post-painting treatment: sealing treatment or heat treatment should be carried out immediately after painting.
Surface treatment: After tungsten carbide spraying, the tungsten carbide sprayed layer should be polished to ensure dimensional accuracy. In addition, safety protection should be carried out when spraying.
High-speed and high-temperature spray protection for workers and tungsten carbide spraying equipment, including ventilation of dust and spraying dust, and safety protection for spraying noise and arc radiation.
