为获得高质量、厚的陶瓷涂层，开发了一种基于溶胶-凝胶的涂层技术。所制备的薄膜为陶瓷-陶瓷0-3型复合材料，由陶瓷粉末在溶胶-凝胶溶液中分散而成。所得系统具有Sol Gel的所有优点，即易于制造、能够涂覆复杂的几何形状和相对成本效益，但不限于薄膜厚度。制备了厚度在5-200微米范围内的锆钛酸铅(PZT)、氧化钇和氧化铈稳定的氧化锆膜、氧化钛膜、二氧化硅膜和氧化铝膜。PZT薄膜的电学性能与块体陶瓷相当，氧化锆膜和氧化铝薄膜具有良好的耐蚀耐磨涂层、热障涂层和性能增强涂层的潜力。
A sol gel based coating technology has been developed for making high quality, thick ceramic coatings. The films are ceramic-ceramic 0-3 composites made by dispersing ceramic powders in a sol gel solution. The resulting system has all the benefits of sol gel, i.e. ease of fabrication, ability to coat complex geometries and relative cost effectiveness, but is not limited in film thickness. Lead zirconate titanate (PZT), yttria- and ceria-stabilized zirconia, titania, silica and alumina films have been fabricated in the 5-200 mu m thickness range. The electrical properties of the PZT films are comparable with those of the bulk ceramic, and the zirconia and alumina films exhibit excellent potential as corrosion- and wear-resistant coatings as well as thermal barrier and performance enhancing coatings.
