Current Work




Production and characterization of ZrCN-nAg coatings deposited onto stainless steel 316L (SS316L) by unbalanced magnetron sputtering with the purpose of preventing bacteria attack and improving the mechanical and tribological properties of joint orthopedic devices. The segregation of silver to the coatings surface and its controlled released are been studied to control the Ag+ release to the environment during the orthopedic device lifetime, enhancing the bactericidal effect and the durability of the implant.
