A Brief Analysis Of Wear-resistant Ceramic Coating With Corrosion Resistance And High Wear Resistance Wear-resisting Status Of Workpiece

With the continuous development of high and new technology, the working conditions of engineering machinery, equipment and components have become increasingly harsh, such as water wheel blades, hydropower station gate and grinding disc of pulp mill, etc., they not only work in a strong corrosive environment, but also constantly moving and rotating, bearing the impact and wear of different media. Some anti-corrosion coatings due to the formation of the coating does not have enough mechanical strength and wear resistance, after a long time of impact and mechanical action, will soon wear, and even spalling and lose the protection of the substrate.

Wear treatment mode

Wear-resistant ceramic coating is mainly composed of some inorganic oxides. Its coating has the characteristics of wear-resistant, acid-alkali corrosion resistance, impact resistance, high insulation strength and no need for bottom coating. It is suitable for road traffic wear-resistant parts, driving ground, anti-erosion blade, hydraulic turbine, pump blade or shell, wear-resistant chassis, conveyor belt wear-resistant parts.

Properties of wear-resistant ceramic coatings

1, single component paint, environmentally friendly, convenient construction, save coating, stable performance, good recoating performance, easy maintenance.

2, coating high hardness, some models up to 9H, dense wear resistance, sand wear resistance, surface smoothness can be adjusted, but also grinding processing.

3, the coating has a certain self-lubrication function, the friction coefficient is relatively low, the more the more smooth, good wear resistance.

4, coating acid and alkali resistance, corrosion resistance, salt spray resistance, anti-aging, can be used for outdoor or high humidity and high heat conditions.

5, coating and substrate combination is good, combined strength is greater than 4MPa.

6. Inorganic composite coating, some models have good electrical insulation performance, insulation resistance is greater than 500MΩ, some models contain graphene, conductive.

7. Some models of coatings are optimized with graphene, which has good graphite high hardness, wear resistance, corrosion resistance and thermal conductivity.

8, coating (ceramic) some models good heat conduction and heat dissipation, thermal conductivity about 12W/M.K.

9, the coating itself is non-combustible, with good flame retardant effect.
