Coating Techniques For Materials Medical: A Mini-Review

The coatings used for biological applications can be made from metals, polymers, ceramics or can be composite coatings, co-deposited or layered (hybrid or sandwich coatings. Currently, a new challenge for scientific researchers is to combine the superior properties of metals and the properties of bioactive materials. Many researches have focused on the development of techniques for coating or depositing bioactive materials on metal substrates to improve the mechanical, tribological and biomedical properties of implants.The most commonly used coating techniques are: direct electrocathodic deposition (ECD), pulse electrocathodic deposition (PED), electrophoretic deposition (EPD), plasma electrochemical oxidation (PEO) or micro-arc oxidation (MAO), chemical vapor deposition (CVD), plasma vapor deposition (PVD), pulsed laser deposition (PLD) and more.
