THE EFFECT OF THE PARTICLE SIZE FRACTION OF CR3C2-NICR POWDER ON THE STRUCTURE AND PROPERTIES OF COATINGS DEPOSITED BY THE HVOF METHOD

Al-Cu-Fe quasicrystalline coatings were deposited onto AISI 321 stainless steel substrates using the high-velocity oxygen fuel (HVOF) spraying method at oxygen pressures of 3.0 and 3.5 bar. The effect of oxygen pressure on the phase composition, microstructure, porosity, corrosion behavior, and thermal stability of the...

Structural-Phase Evolution and Morphology of Cobalt-Free WC Hard Alloys Produced by SPS

This study examines the effect of spark plasma sintering (SPS) temperature on the phase composition, microstructure, densification, and microhardness of cobalt-free WC–Fe and WC–Fe–Ni hard alloys. Increasing the sintering temperature from 1250 °C to 1300 °C improved densification in both alloy systems. Residual porosit...
