Abstract: A metal matrix composite material was obtained by self-propagating high temperature synthesis (SHS) from powder mixtures of titanium, carbon (carbon black), and high chromium cast iron of PG-S27 trademark. Synthesized products were crushed and sieved to get a composite powder for plasma spraying of wear resistant coatings. The coatings were tested for hardness and abrasive wear resistance. According to X‑ray diffraction and scanning electron microscopy investigation, the structure of coatings involved fine TiC particles uniformly distributed over the cast iron matrix. It was ascertained that the coatings plasma sprayed with the SHS composite powder had a hardness 2 times greater and abrasive wear resistance 3.5 times greater than that of plasma sprayed with the cast iron powder.
