The surface of graphite was modified employing powder immersion reaction assisted coating (PIRAC) method. Graphite plates were immersed into Ti powder and annealed at 800–1000 ◦C. Crystalline iodine was admixed to Ti powder in order to accelerate the transfer of Ti atoms onto the graphite surface. As a result of interaction between Ti and graphite, continuous Ti carbide coatings were formed with a thin layer of stiochiometric TiC on the graphite substrate/coating interface and Ti-rich TiC1−x in the outer part of the coating with concentration of carbon decreasing towards the surface of the coating. The coatingwas found to growby a parabolic lawwith the kinetic constant, k=3.7≠10−8 exp(−160,000/RT)m2/s, the process being controlled by diffusion along fast diffusion paths. At low iodine concentrations and short exposures the amount of admixed iodine affected the rate of titanium carbide coating growth. A kinetic model of the process of coating growth is proposed.
