Microstructure and Wear Resistance of Detonation Coatings Obtained from Titanium Carbide–Nichrome SHS Powders Having Different Particle Sizes

Microstructure and Wear Resistance of Detonation Coatings Obtained from Titanium Carbide–Nichrome SHS Powders Having Different Particle Sizes

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 spraye...

Zusammenfassung: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 Cr 3 C 2 –NiCr 21 vol % commercial cermet powder (PraxAir 1375VM, USA) with particle sizes ranging from 20 to 45 μm.
