1. What is ceramic spraying on metal surfaces: It refers to materials prepared by depositing a ceramic layer on metal surfaces. Such materials combine the strength and toughness of metals with the high-temperature resistance, wear resistance, corrosion resistance and other properties of ceramics.
2. Where is ceramic spraying applied: Ceramic spraying technology on metal surfaces has been successfully used in industries including aviation, aerospace, national defense, chemical engineering, machinery, electric power, cables and electronics. 3. What are the features of ceramic spraying: The ceramic coating on metal surfaces can modify the morphology, structure and chemical composition of the metal substrate surface, endowing the substrate with new properties. 4. Advances in modern science and technology have not only improved coating preparation technologies but also expanded the range of available coatings. Let’s take a look at thermal spraying technology! 5. Thermal Spraying Technology This technology uses heat sources such as flame, electric arc or plasma to heat wire or powder feedstock to a molten or semi-molten state. The material is accelerated into high-speed molten droplets, which are sprayed onto the substrate to form a coating. It strengthens or restores surface properties of materials (wear resistance, corrosion resistance, heat resistance, etc.) for protective purposes, and repairs parts whose dimensions have been reduced due to wear, corrosion or out-of-tolerance machining. Meanwhile, it can also impart special functional properties to material surfaces (electrical, optical, magnetic, etc.) Advantages: 1. There is no restriction on the composition of spray materials, which can be selected as required, and composite coatings can also be formed; 2. Low substrate temperature; the workpiece temperature can be maintained between 30℃ and 200℃. There is no limit on the size of components to be sprayed; 3. Wide coating thickness range, from tens of micrometers up to 1 millimeter; 4. Simple spraying equipment. The equipment can be moved directly to the site for on-site spraying, with few operating procedures, high efficiency and fast coating formation speed.
