Nickel based superalloy are in demand for high temperature applications and their corrosion, erosion wear resistance have been investigated a long time. chromium (NiCr) alloys widely used corrosion resistant coatings, while carbide nickel (CrC-NiCr) preferred coatings at temperature. In this study CrNiAlCY were deposited via liquid fuelled velocity oxy fuel (HVOF) thermal spray using two parame...

A nanostructured hydroxyapatite (HA) feedstock was thermally sprayed on Ti–6Al–4V substrates via high velocity oxy-fuel (HVOF process). The particle temperature and velocity for the HA particles in the HVOF jet were monitored during spraying and found to be 1826± 346 ◦C and 638± 82 m/s, respectively. The bioactivity of the coating was investigated in a simulated physiological environment, as an...
