Abstract
An analysis of methods for the formation of amorphous and crystal-amorphous materials and coatings is presented. The factors that influence the formation of an amorphous structure in materials are studied. The coatings made by cathodic-arc deposition with two single-component titanium and aluminum cathodes are deposited onto high-speed steel samples. Using X-ray diffraction analysis, the influence of the location of the sample in the vacuum chamber relative to the center on the degree of crystallinity of the coating structure is determined. Investigations of the influence of the speed of rotation of the working table about the axis on the percentage of the amorphous phase in the intermetallic coatings are performed. It is discovered that the highest content of the amorphous component is observed in the samples farthest from the axis of the table. This is due to the fact that the samples are under conditions of relatively rapid cooling. Based on the research results, a coating technology based on intermetallic compounds of the system (Ti,Al)N with an amorphous-crystalline structure made by cathodic-arc deposition with two single-component cathodes is developed.
