IOP Conference Series: Materials Science and Engineering Vol. 511. P. 012030 (1-5)Abstract: The results of the research of the phase composition and the mechanical properties of the coatings on the basis of the Zr-Y-O system produced by pulsed magnetron sputtering on the K208 glass substrates are presented in this paper. By the X-ray diffraction method it has been discovered that there is the ZrO2 phase in two modifications in the coatings. The deposition of the Zr-Y-O coating system allows not only to increasing the microhardness of the surface layer of the K208 glass up to ~19 GPa, but also maintain a high level of the elastic properties (We> 0.70). The laboratory tests have been carried out on the impact of the high-speed flows of iron microparticles on the Zr-Y-O protective coating produced by pulsed magnetron sputtering. When a high-speed flow of iron microparticles impact the samples with the Zr-Y-O coatings the surface density of the craters decreases ~ 7 times compared with initial state.
