Article

The paper examines the phase and structure formation during hot pressing of titanium carbide electrode materials as well as the structurization and properties of spark-deposited coatings on steel substrates. The influence of the operating current used for erosion processing on the phase composition and hardness of the coatings is established. It is shown that the electrode materials with a certain composition and structure enable the electrospark deposition of 100 μm-thick coatings with hardness to 14 GPa. The mass of the material deposited on a steel substrate is three times higher than that formed using standard titanium carbide alloy TN20. The wear resistance of the coatings in abrasive and dry sliding friction is high, hence they may be recommended for protection of steel parts for severe wear applications.
