...在氧化锆内部添加3%的氧化钇以后,四方晶相便可以存在于常温,如许在应力感化下四方晶相可以转变成单斜晶相(Monoclinic Zirconia),此时晶格的体积是增大年夜的,因此在微裂纹的四周产生压应力,使微裂纹趋于封闭,从而进步了氧化锆质料的断裂韧性,或说质料获...

The results indicate that the coating is mainly composed of tetragonal and cubic phase and a small amount of monoclinic zirconia.
结果表明,涂层主要以四方相和立方相构成,并含有少量的单斜相。
It is found that the increase of oxygen vacancy content can increase the instability of the metastable tetragonal phase and accelerate the transformation to monoclinic zirconia.
结果表明:氧空位的存在与变化不仅影响着氧化锆相结构的稳定性,而且影响着氧化锆的低温相变过程。
Experimental results indicate that a high reaction temperature and quickly ascending temperature speed apparently increase the nucleation number of monoclinic zirconia in the precursor solution.
