Abstract
The invention relates to the protective coatings. A coating contains a ceramic composition on the base of zirconium dioxide stabilized by yttrium oxide consisting of inner porous layer and outer dense layer. The outer dense layer additionally contains aluminum oxide. Ratio of thickness of inner porous ceramic layer and outer dense one makes 0.3-20.0.
