【摘要】：从功能、用途方面分类综述了耐磨、耐蚀以及热障三大类高性能陶瓷涂层,在此基础上,介绍了高性能陶瓷涂层常用的制备工艺,重点探讨了不同制备方法的特点和适用场合,指出了制备方法的发展方向。物理气相沉积技术(PVD)制备的陶瓷涂层纯度高、致密性好,并且与基体结合牢固,但其生产成本高,生产效率低,因此物理气相沉积技术向着高效率、低成本的方向发展。化学气相沉积技术(CVD)制备的陶瓷涂层涂覆率高、致密性好,但其反应温度高,并且伴随着有毒有害气体产生,因此化学气相沉积技术向着低温、环保的方向发展。等离子喷涂技术(PS)制备陶瓷涂层成本低、效率高、适应性强,但涂层孔隙率高,并且涂层与基体的结合强度低,因此等离子喷涂技术向着高致密、高结合强度的方向发展。激光熔覆技术制备的陶瓷涂层组织细小、力学性能优良,但其操作工艺复杂,产品质量很难控制,因此激光覆熔技术向着工艺简单、质量可控的方向发展。最后,展望了高性能陶瓷涂层及其制备工艺的发展方向和可能的研究内容。
[Abstract]:From the function, use the classification of wear resistance, corrosion resistance and thermal barrier and three kinds of high performance ceramic coatings, based on this, introduced the preparation of commonly used high performance ceramic coating preparation technology, discussed the characteristics of different preparation methods and application, and points out the development direction of preparation method. Physical vapor deposition technology (PVD) ceramic coating prepared by high purity, good compactness, and combined firmly with the substrate, but its high production cost, low production efficiency, so the physical vapor deposition technology towards high efficiency, low cost direction. Chemical vapor deposition technology (CVD) ceramic coating prepared by high rate good compactness, but its high reaction temperature, and accompanied by the poisonous and harmful gases, so the chemical vapor deposition technology to low temperature, the direction of environmental protection. Plasma spraying (PS) ceramic coating was prepared with low cost, high efficiency, strong adaptability, but The porosity of the coating, and the coating and the substrate bonding strength is low, so the plasma spraying technology to high density, high bonding strength in the direction of the development of laser cladding technology. The microstructure of ceramic coating prepared by fine, excellent mechanical properties, but its complex operation process, product quality is difficult to control, so the laser laser cladding technology to simple process the direction of development, quality control. Finally, the prospects of development of high performance ceramic coating and its preparation process and possible research content.
