What is the function and principle of ceramic spraying?

       1. What is spraying ceramic on metal surface: The material made by coating a ceramic layer on the metal surface not only has the strength and toughness of metal, but also has the resistance of ceramic.

High temperature, wear and corrosion resistance properties.

2. Application occasions of ceramic spraying: The ceramic spraying technology of metal surface has been successfully applied in aviation, aerospace, national defense, chemical industry, machinery, electric power, cable, electronics and other industries.

3. What are the characteristics of ceramic spraying: The ceramic coating on the metal surface can change the morphology, structure and chemical composition of the metal collective surface, and give the substrate new properties.

 

4. The development of modern science and technology has not only brought about the improvement of coating preparation technology, but also the increasing number of coating types. Let's take a look at thermal spraying technology!

5. Thermal spraying technology

The technology is to heat a wire or powdered material to a molten or semi-melted state through a heat source such as flame, arc or plasma, and accelerate the formation of high-speed droplets.

It is sprayed to the substrate to form a coating, so as to strengthen or regenerate the surface properties of the material (wear resistance, corrosion resistance, heat resistance, etc.)

Repair the part size reduction caused by corrosion or machining tolerance. At the same time, it can also endow the surface of the material with special properties (electricity, light, magnetism, etc.)

advantage:

 

1. The composition of the spraying material is not limited, it can be selected according to the requirements, and a composite coating can also be formed;

 

2. The temperature of the substrate is low, and the temperature of the workpiece can be maintained at 30-200 °C; the size of the components to be sprayed is not limited;

 

3. The coating thickness range is wide, from tens of silk meters to 1 mm;

 

4. The spraying equipment is simple, and the equipment can be directly moved to the site for spraying, with few operating procedures, high efficiency, and fast coating formation.
