What is spray welding and what are its significant advantages compared with

Spray welding is to reheat the preheated self-soluble alloy powder coating to 1000-1300℃, so that the particles are melted and the slag floats to the surface of the coating. The generated boride and silicide are dispersed in the coating, so that the particles and the substrate surface are well bonded.

The difference between spray welding

The difference between spray welding

The bonding formation of the spray coating and the spray welding layer with the base metal is different. When the nickel-clad aluminum is heated by the spray flame beam, an exothermic chemical reaction occurs, and a micro-metallurgical bonding bottom layer and the working layer are formed on the surface of the carbon steel that has been sandblasted and rust-removed to Sa3 level and RZ>50μm, and a mechanical bonding coating with an "anchor hook" effect is produced. The bonding between the spray welding layer and the base is purely a metallurgical bonding coating.

Thermal spray technology

Thermal spray technology

It refers to a technology that uses a certain heat source, such as an electric arc, plasma arc, combustion flame, etc. to heat powdered or filamentary metal and non-metallic coating materials to a molten or semi-molten state, and then uses the power of the flame flow itself or an external high-speed airflow to atomize and spray at a certain speed onto the surface of the pre-treated substrate material, and combines with the substrate material to form a surface coating with various functions. During the spraying process, the molten particles hit the substrate surface and spread into thin sheets, and instantly cool and solidify. Subsequent particles continue to hit the previously formed thin sheets and accumulate to form a coating.

Explore the multiple applications and advantages of APS plasma thermal spray technology

In the internal combustion engine industry, the traditional cast iron cylinder liner, which was once the most widely used and common, has gradually ushered in a technological revolution. APS plasma thermal spraying technology, as a new surface coating process, is redefining engine cylinder bore technology and also showing great potential in other fields.
