| Abstract: |
| Three types of high performance ceramic coating, namely, wear-resistant ceramic coatings, corrosion-resistant coatings and thermal barrier coatings, were reviewed in terms of function and application. On this basis, common preparation techniques of high performance ceramic coatings were introduced, characteristics and applications were investigated emphatically, and development direction of different preparation methods was pointed out. Ceramic coatings prepared in PVD method featured in high purity, high compactness and good cohesion with substrate, but they had such disadvantages as high production cost and low production efficiency, so the PVD technology was developed in the direction of high efficiency and low cost. The ceramic coatings prepared in CVD method featured in high coating rate and high density, but they had such disadvantages as high reaction temperature, so the CVD technology was developed in the direction of low temperature and environmental protection as poisonous and harmful gases were produced. The ceramic coatings prepared in PS method featured in low cost, high efficiency and good adaptability, but they had such disadvantages as high coating porosity, and low coating-substrate bonding strength, so PS was developed in the direction of high density and high bonding strength. The ceramic coatings prepared in PS method featured in fine microstructure and good mechanical properties, but they had such disadvantages as complex operation technique and uncontrollable product quality, so laser cladding technology was developed in the direction of simple process and controllable quality. Finally, the development direction and potential research content of high performance ceramic coatings and their preparation technologies were prospected. |
