COMPOSITE LASER-CLAD COATING ON TITANIUM SUBSTRATE USING PURE HYDROXYAPATITE POWDER

Abstract

Biocomposite (or bioceramic) materials have become very popular, especially for replacing some human bone parts, such as hip joints, knee joints, and producing implants for dentistry and others. It is supposed that cladding coatings with hydroxyapatite (HA) on a metallic substrate could be a good solution for implants. Production of laser cladding coatings using pure HA powder and titanium substrate is investigated.
