研究了La2O3对Y2O3稳定ZrO2等离子喷涂涂层的热导率、相稳定性和热循环寿命的影响。虽然低的热导率以及高的抗烧结性是通过添加La2O3实现的，但它往往也会导致涂层的相稳定性和热循环寿命较低。涂层组成和结构的优化改善了这些性能，并且优化的涂层显示出延长的热循环寿命。
The effects of La2O3addition on thermal conductivity, phase stability and thermal cycle life of Y2O3stabilized ZrO2plasma sprayed coatings were investigated. Although low thermal conductivity as well as high resistance to sintering was achieved by La2O3addition, it tended to also result in lower phase stability and thermal cycle life of the coatings. Optimization of the composition and structure of the coatings improved these properties, and the optimized coatings showed prolonged thermal cycle life.
