Wococarbide Provides Thermal Spraying Powder

       

Wococarbide provides thermal spraying powder. So, what factors should we consider when we conduct thermal spraying? How to correctly select thermal spraying coating? We should carefully evaluate the performance of the coating under the working conditions of the workpiece, the physical and chemical properties of the spraying material and the base material, and make careful tests in combination with the application technology of the coating. Wococarbide metal thermal spraying mainly considers the following factors:

(1) Possibility of process method

For example, in terms of the use requirements of components, it is appropriate to conduct melting treatment after spraying nickel base self melting alloy, but for some reasons (such as thermal deformation of components, protective treatment with electroplating or organic coating, inability to withstand coating melting temperature, etc.), this process method cannot be used. When selecting the process method, the machinability of the spraying layer shall also be considered, and the machinability, which machining method to adopt, and the processing cost shall be considered according to the size and shape of the parts.

(2) Working environment

Including the stress or impact force borne by the coating during operation, working temperature, corrosive medium and corrosive environment, materials and lubrication of the mating surface and connecting surface between the coating and other parts, etc.

(3) Required coating properties

It includes the surface functions of the coating, such as surface state, surface finish, chemical properties of the coating, adhesion strength, porosity and hardness of the coating, anti-corrosion performance, wear resistance, friction performance, electrical performance, heat resistance and thermal conductivity, coating thickness and finishing performance, etc.

(4) Characteristics of matrix materials

The size and shape of the sprayed parts, the surface state of the sprayed parts, the density and quality of the parts, the sensitivity of the base material to temperature, the chemical composition, hardness and thermal expansion coefficient of the base material, the stress state in the parts, and whether other surface treatments have been carried out before thermal spraying.
