The paper presents an analysis of methods for obtaining an optically black light-absorbing coating by microarc oxidation on valve metal alloys. The formulation of a universal electrolyte and processing modes for the formation of an optically black coating on aluminum and titanium alloys are revealed. The dependences of the parameters of the processing modes on the properties of coatings are established. The resulting oxide layer has a high degree of blackness and has a homogeneous structure. The results of the study can be used when applying optically black MDO coating on products of rocket and space technology.
