The role of processing parameters on calcium phosphate coatings obtained by laser cladding

Laser surface cladding has become an extensively technique used in metallurgical applications in order to improve surface properties of materials. We have proposed this technique in the field of biomaterials to coat the surface of titanium alloy substrates used in orthopaedical implants with a calcium phosphate (CaP) bioceramic to promote the growth of the bone when the implant is inserted in the body. An exhaustive study about the influence of the processing parameters on the CaP coating properties was carried out. To tackle this subject, an appropriate selection of the relevant processing parameters was done.
