1. It can organically combine the strength and toughness and ease of processing of metal materials with the high temperature resistance, wear resistance and corrosion resistance of ceramic materials.
2. Reasonable selection of coating materials and suitable spraying process can obtain surface strengthening coatings with various functions.
3. Not limited by the substrate: the substrate material used for thermal spraying can be inorganic materials such as metal, ceramics, cement, refractory materials, stone, gypsum, etc., or organic materials such as plastic, rubber, wood, paper, etc.
4. Not limited by the size of the workpiece and the construction site.
5. The coating deposition rate is fast, the thickness can be controlled, and the process is simple.
6. The processability of the ceramic coating is good, and the coating can be sprayed after the coating is damaged.
High-temperature rollers such as heat treatment furnace rollers, backup rollers, sintering furnace rollers, etc. mostly operate at a temperature of 800 ℃-1200 ℃, using thermal spraying technology, spraying special ceramic or cermet coating on the surface of the high temperature furnace roller, which has good high temperature resistance and resistance Oxidation, anti-adhesion, anti-nodule and self-cleaning and purification functions can improve the service life of furnace rolls, and can produce steel with excellent surface quality. Under the conditions of low stress sliding wear and abrasion, almost all the original chrome-plated products can be replaced with thermal spray ceramic coatings.
