The study objective is to evaluate the influence of the technological parameters of microarc oxidation on the thermophysical properties (thermal conductivity coefficient) of MAO coatings obtained on samples of titanium (VT20) and aluminum (D16) alloys. The study task is to find the interconnections between the characteristics of MAO coating (thickness, porosity, composition), the type of electrolyte, and the thermal conductivity coefficient of the resulting oxide-ceramic coatings. A patented microarc oxidation technology was used to form oxide coatings on the surface of experimental samples made of VT20 and D16 alloys. The novelty of the work is in the application of original technical solutions that make it possible to create composite metal materials with an oxide-ceramic coating by microarc oxidation. The study shows that the developed materials are effective and will expand the scope of possible applications of traditional structural materials and products made from them. A relevant area in the field of creating materials with high thermal insulation properties is microarc oxidation (MAO).
