Abstract
With the rapid development of modern industry, higher requirements are put forward for the corrosion resistance of materials. Because of its excellent chemical stability and good mechanical properties, chemical corrosion resistant ceramic coating has shown a wide application prospect in chemical industry, aerospace, biomedicine and other fields. In the chapter of the preparation process of ceramic coating, the preparation process of physical vapor deposition, chemical vapor deposition, sol-gel, mechanical alloying and powder sintering are introduced in detail, and their process characteristics and application range are compared and analyzed. In particular, the process parameters of vacuum evaporation and plasma enhanced chemical vapor deposition in physical vapor deposition, sputtering deposition in chemical vapor deposition, pyrolysis chemical vapor deposition in chemical vapor deposition, and sol-gel method are discussed in depth. The influence of different process parameters on the coating structure, the influence of process selection on the corrosion resistance of the coating, and the influence of the process on the bonding strength of the coating are discussed. Through experimental data and theoretical analysis, the internal relationship between process parameters and coating properties is revealed. In the chapter of ceramic coating performance testing and analysis, this paper systematically introduces the coating performance testing methods, including chemical stability testing, mechanical properties testing and thermal stability testing, and uses modern analytical techniques such as scanning electron microscopy, X-ray diffraction and transmission electron microscopy to analyze the microstructure of the coating in detail. In addition, the factors affecting the coating properties were evaluated comprehensively, which provided a scientific basis for the optimization of coating properties. Finally, in the chapter of application research of chemical corrosion resistant ceramic coatings, the application of coatings in chemical equipment, aerospace, biomedicine and other fields is discussed, and its application prospect is prospected.
