Discharge ignition modes of an LG are studied. Conditions of discharge propagation to the anode in the presence of an additional discharge electrode are experimentally investigated. A dependence of an ignition delay on parameters of pulse current of the cathode is shown by an experiment. A comparison of various discharge ignition modes is performed for different discharge path configurations.

The equipment, procedure and the results of investigations of the bonding strength of gas-flame coatings with the substrate are described. The dependence of the bonding strength on the conditions of spraying with the powder materials using the hydrogen–oxygen flame is outlined.

The method of high-speed electric thermal diffusion hardening of components working in the conditions of abrasive wear and high loads is described. Hardness can be greatly increased by replacing high-carbon steel by a steel with a lower carbon content in the manufacture of soil cultivating machinery.
