Abstract
The paper examines the composition and structure of electrospark coatings based on AlN-TiB2 (TBSAN) and AlN-ZrB2 (TsBSAN) electrode materials deposited on VK8 alloy. Kinetic dependences of mass transfer are studied. In spite of the close structures and mechanical properties of TBSAN and TsBSAN electrode materials, the coatings substantially differ in structure and properties. The kinetic dependences of mass transfer, which differ for TsBSAN and TBSAN electrodes, generally confirm that the mass transfer in electrospark alloying of a hard-alloy substrate occurs in three stages and show distinctions in the electroerosion mechanism for these electrode materials.
