Abstract

Results of studying the structural-phase state and mechanical properties of Al–Si–N coatings fabricated by pulsed magnetron sputtering on a K-208 glass substrate are presented. By the method of X-ray diffraction analysis it has been found that the Al–Si–N coatings with a thickness of 6 μm contain nanoscale hexagonal close-packed (HCP) AlN crystallites. Sputtering of the Al–Si–N coatings allows the nanohardness of the surface layer of the K-208 glass samples to be increased up to 30 GPa and a high level of elastic properties (We ≈ 70%) to be maintained. For the examined samples, laboratory tests on the impact of high-speed flows of iron microparticles on the Al–Si–N protective coatings fabricated by the method of pulsed magnetron sputtering have been performed. It is established that sputtering of the Al–Si–N protective coatings with a thickness of 6 μm allows the resistance of the K-208 glass samples to the impact of iron particles accelerated up to 8 km/s to be increased by a factor of 2.8.
