Abstract

The size effect of particles (20–45, 45–56, 56–71, 71–90 μm) of TiC–NiCr n vol % (n = 30, 40, 50) self-propagating high-temperature synthesis (SHS) cermet powders synthesized in the direct combustion mode on the tribological characteristics of detonation coatings is studied. These powders are sprayed in a mode optimized previously using Cr₃C₂–NiCr 21 vol % commercial cermet powder (PraxAir 1375VM, USA) with particle sizes ranging from 20 to 45 μm.
