Electrospark‐Deposited AlCrFeCoNi High‐Entropy Alloy Coatings on Steel: Microstructure Evolution, Mechanical Properties, and Corrosion Response

Advanced Engineering Materials, Volume 28, Issue 1, January 2026.
AlCrFeCoNi high entropy alloy coating is applied on steel using electrospark deposition. The microstructure evolution and phase transformation of the as‐deposited and heat‐treated coatings is characterized and discussed. Reduced microhardness and yield strength are measured after heat treatment.

HVOF spraying of nanostructured hydroxyapatite for biomedical applications

Materials Science and Engineering: A, 2005
Abstract 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.
