Coatings

Ceramed offers a wide variety of advanced coatings technology solutions as also surface treatments, such as the success of Hydroxyapatite coating (HaP), the high osseous-integration capability of titanium plasma spray (Ti), as also the PVD coating that allows apply biocompatible ceramics, with wear protective and anti-allergic coatings for orthopedic implants and surgical instruments. times and excellent track record that accompany every treatment we offer.Ceramed activities are focused on the needs of our clients, and bearing that in mind.


Plasma

Hydroxiapaptite Coating:
    HAp is a calcium phosphate ceramic, which has the ability of accelerating the reconstruction of the bone tissue on the metallic implant surface creating a rapid bonding. When using implants coated with HAp it is expected that, once inserted into the human body, the interaction between the implant and the body tissues lead to the formation of live bone tissue around the implant. HAp coatings enhance the growth of bone tissue through the coating pores, which gives good mechanical stability to the fixation process of implants.
Titanium Coating:
    Ti coating is porous and rough, which allows the bone ingrowth into the coating voids, creating a firm fixation between the implant and tissues and reduces the pressure at the bone-implant interface.
Double layer (Ti+HAp) Coating:
    Ti+HAp coating is the combination of each coating process. This coating combines the advantages of the roughness and porosity of the Ti and the bioactivity of HAp, which accelerates the bone reconstruction on the implant surface, ensuring a rapid bonding of the implant in the patients tissues.






PVD

PVD (Physical Vapor Deposition) coatings with TiN and TiNbN present several advantages in surgical instruments and medical devices. This process attributes a high toughness along with a low shear coefficient, giving the instrument a higher cut attribute, a high density, which makes it an excellent barrier to any aggressive chemical environment, and an excellent biocompatibility, presenting a low or inexistent diffusion rate, preventing the appearance of prosthesis material in the surrounding tissues.





Anodization

Due to its properties of flexion resistance and fatigue resistance Ti is used in biomedical application in mechanical support, orthopedic and dental, and in pacemakers. The oxidation of titanium and its alloys in the implants surface is responsible for the corrosion resistance increase, and therefore its stability in vivo. These properties improve its behavior when implanted.

The anodization process accelerates the formation of the oxide layer under controlled conditions to provide the desired result. CERAMED developed two types of anodization treatments: grey anodization and color anodization.
