Biomedical Implant Coatings
In 1980, biomedical implants were a viable option for patients in need of joint replacement, but the orthopaedic marketplace was unable to create a strong, permanently fixed, cementless implant. As a result of the demand for a better implant, APS derived the process of applying porous and bio-active coatings to orthopedic implants. Today, APS produces commercially pure titanium (CP Ti) and hydroxyapatite (HA) orthopaedic implant coatings for 7 of the 10 largest medical manufacturers in the world. APS' titanium (Ti 6AL 4V) and hydroxyapatite (HA) coatings are especially coveted by the biomedical industry because the materials are particularly wear-resistant and they promote osseointegration between bone and implant.
The advantages of the titanium and hydroxyapatite (HA) coatings lie not only in their physical properties, but also in mechanical properties related to device design and functionality. The unique physical and mechanical properties of these coatings are the highlights of a unique thermal spray process that is used to coat medical implants. Plasma spray technology enables the biomedical engineer to design an implant that provides the highest achievable mechanical properties while also providing implants that exhibit superb synthetic bone properties.
