The research presents the principles of development and practical implementation (including rational modes) of combined treatment technology for the surface of precision parts with a broad beam of ions and/or fast argon atoms. In a single technological cycle, two process stages are realized: polishing with a beam at an incidence of 80º to the surface of parts made of different material, which enables a precision level of the surface roughness and deposition of protective nanostructured films on the parts immersed in dense plasma produced by magnetron sputtering in a mixture of inert and reactive gases. The developed innovative technology has a wide range of technological applications, but a particularly promising area is the processing of optical parts and elements.
The research aims to investigate the effect of depositing nitride and Si-containing amorphous hydrogenated carbon films on the characteristics of SiAlON-based ceramics experimentally. The effect of TiN/(Ti,Al)N, (Cr,Al,Si)N and (Cr,Al,Si)N/a-C:H:Si coatings on the microrelief and surface defects of ceramics was studied. The nanohardness, plasticity, and coefficient of friction of the ceramic material at room temperature and under heating conditions after applying the mentioned coatings were quantified. Laboratory durability tests of ceramic mills with different coatings during machining a heat-resistant nickel alloy were carried out. A qualitative assessment of the nickel adherence intensity on the work surfaces of ceramic tools during cutting was performed.
