摘要：

Prespray annealing of commercially available hydroxyapatite (HAp) plasma-spray powder at 1300 degrees C for 1 h in air leads to substantial densification without noticeable thermal decomposition. The resulting HAp coatings, low-pressure plasma sprayed onto Ti-6Al-4V substrates, show a dense microstructure, improved adhesion strength, and higher resorption resistance when treated for 7 days in simulated body fluid (Hank's balanced salt solution).
