In the present paper, the effect of deposition temperature on the structure, morphology, hardness, electrochemical evaluation, degradation properties and functional peptides adhesion of Mg and Si-doped hydroxyapatite was investigated. The coatings were obtained by RF magnetron sputtering technique at room temperature (RT) and 200 \u00b0C on AZ31B alloy substrate. Results showed that an increase in deposition temperature led to an improvement in hardness and reduced modulus of about 47%. From an electrochemical point of view, a comparative assessment of corrosion resistance was made as a function of the immersion medium used, highlighting the superior behaviour revealed by the coating deposited at elevated temperature when immersed in DMEM medium (icorr~12 \u00b5A\/cm2, Rcoat = 705 \u03a9 cm2, Rct = 7624 \u03a9 cm2). By increasing the deposition temperature up to 200 \u00b0C, the degradation rate of the coatings was slowed, more visible in the case of DMEM, which had a less aggressive effect after 14 days of immersion. Both deposition temperatures are equally suitable for further bio-inspired coating with a mussel-derived peptide, to facilitate biointegration.<\/jats:p>","DOI":"10.3390\/coatings13030591","type":"journal-article","created":{"date-parts":[[2023,3,10]],"date-time":"2023-03-10T08:02:08Z","timestamp":1678435328000},"page":"591","source":"Crossref","is-referenced-by-count":3,"title":["Effect of Deposition Temperature on the Structure, Mechanical, Electrochemical Evaluation, Degradation Rate and Peptides Adhesion of Mg and Si-Doped Hydroxyapatite Deposited on AZ31B Alloy"],"prefix":"10.3390","volume":"13","author":[{"given":"Anca Constantina","family":"Parau","sequence":"first","affiliation":[{"name":"Department for Advanced Surface Processing and Analysis by Vacuum Technologies, National Institute of Research and Development for Optoelectronics\u2014INOE 2000, 77125 Magurele, Romania"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-3149-6972","authenticated-orcid":false,"given":"Mihaela","family":"Dinu","sequence":"additional","affiliation":[{"name":"Department for Advanced Surface Processing and Analysis by Vacuum Technologies, National Institute of Research and Development for Optoelectronics\u2014INOE 2000, 77125 Magurele, Romania"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-8991-7485","authenticated-orcid":false,"given":"Cosmin Mihai","family":"Cotrut","sequence":"additional","affiliation":[{"name":"Department of Metallic Materials Science, Physical Metallurgy, Faculty of Materials Science and Engineering, University Politehnica of Bucharest, 60042 Bucharest, Romania"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-1368-6219","authenticated-orcid":false,"given":"Iulian","family":"Pana","sequence":"additional","affiliation":[{"name":"Department for Advanced Surface Processing and Analysis b
