Dependence of grain size on temperature in a layer of coating based on Zr-Y-O in a multilayer coating Zr-Y-O / Si-Al-N
The grain structure in the layer of Zr-Y-O in coating on the basis of Zr-Y-O / Si- Al-N depend on annealing time at 900Β°C in the "in-situ" mode
Microstructure and properties of nanocomposite Al-Si-N system coatings produced by magnetron sputtering
The paper presents the results of investigations of the structural and phase conditions, mechanical and optical properties of Al-Si-N system coating obtained by magnetron sputtering. The thickness of this coating ranges from 3 to 19β
Β΅m and is sprayed on silica glass using magnetron sputtering technique. The formation of nanoscale AlN single phase with HCP crystal system and the crystal grain size of up to 20β
nm is discovered using the X-ray diffraction method. The texture of [002] orientation is observed in the structure of Al-Si-N-based coatings. These coatings are characterized by high values of microhardness and coefficient of restitution. The transmission spectrum of the coatings are produced within the range of 190-1100β
nm. Al-Si-N-based coatings are characterized by a high degree of transparency (β 80%) within the visible light spectrum and complete opaqueness in the ultraviolet region. The refractive index and the thickness of Al-Si-N system coating are determined using the transmission spectrum and refractive index. The refractive index of Al-Si-N-coated glass samples is determined using the transmission spectrum the value of which increases with the increase in the coating thickness

Structure and optical-mechanical properties of the Zr-Y-O coatings deposited by pulse magnetron sputtering on optical glass
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
