The research objectives are a wear-resistant electric-spark coatings on aluminum alloys. The goal of this study is to develop wear-resistant electric-spark coatings on aluminum alloys. For this, alloying materials were investigated in terms of regularities of structure formation, mass transfer, phase transformations, wetting, and physical-mechanical properties. XRay-diffractometry, electron-microscope investigation, metallography, microradiography, microprobe and thermogravimetry analysis. The work novelty: we realized for the first time the technology for the electro-spark alloying (ESA) of aluminum alloy surfaces with compact electrodes. The features of structure formation and phase transitions during electric mass transfer were identified. The application area is aircraft space engineering and motor-car construction.
