T1 THIN BIOACTIVE Zn-SUBSTITUTED HYDROXYAPATITE COATING DEPOSITED ON Ti SUBSTRATE BY RADIOFREQUENCY SPUTTERING JF High Temperature Material Processes: An International Quarterly of High-Technology Plasma Processes JO HTM YR 2017 FD 2018-02-08 VO 21 IS 3 SP 191 OP 201 K1 antibacterial activity K1 osteointegration K1 thin coatings K1 plasma coatings K1 biocompatibility AB In this study, Zn-substituted hydroxyapatite synthesized by mechanochemical activation was deposited on titanium substrates by a radiofrequency sputtering method. The microstructure, composition, and sputtering rate of the deposited films were examined. The coatings are formed by an amorphous and quasi-amorphous type of structure with good adhesion to the substrate. The elemental composition of the coatings is close to a stoichiometric hydroxyapatite one with a trace of Zn. It was discovered that it is possible to deposit a thin amorphous coating from a crystalline target by increasing the target-to-substrate distance and subsequently decreasing the substrate temperature. This provides a possibility of forming an antibacterial bioactive coating with a high level of bioresorbability which could be used for a rapid antibacterial effect. Also, amorphous calcium phosphate could be used as a component of a multilayer coating comprised of substituted hydroxyapatite in both amorphous and crystalline forms for improved implant stability.
