You may have heard of tungsten carbide powder, but do you know how to spray tungsten carbide powder? The basic process of WC powder spraying includes substrate surface pretreatment, spraying, surface heat treatment, coating sealing treatment and coating surface finish.
(1) Substrate surface pretreatment: after selecting the spraying method, select degreasing, derusting, surface roughness and other pretreatment processes.
(2) Spraying: when spraying tungsten carbide, reasonable process parameters should be determined to control the spraying quality.
It includes the conditions of injection heat source, i.e. the mixture ratio of fuel and oxygen;
2. Material transportation, i.e. the type, speed, flow rate, position and angle of transportation gas;
Tungsten carbide spraying materials, including material composition, physical properties, powder form, particle size, wire or bar diameter, etc.
Four basic components: substrate temperature, properties and surface treatment methods;
There are five kinds of spraying operations, including the distance between the spray gun and the machine, the speed of the spray gun or the machine parts, the angle between the spray gun and the machine parts, and the spraying of gas medium.
(3) Post coating treatment: sealing treatment or heat treatment shall be carried out immediately after coating.
(4) Surface treatment: after tungsten carbide spraying, the tungsten carbide spraying should be polished to ensure the dimensional accuracy. In addition, safety protection should be carried out in WC spraying.
High speed and high temperature spraying protection for workers and WC spraying equipment, including ventilation of dust and spraying dust, safety protection of spraying noise and arc radiation.
