| Abstract [eng] |
The main aim of this doctoral thesis was to develop an effective synthetic procedure for deposition of calcium hydroxyapatite thin films on variously modified 316L stainless steel substrates and investigate different properties of obtained coatings in order to use the calcium hydroxyapatite coated stainless steel for manufacture of permanent implants. Environment friendly aqueous sol-gel method was developed for the synthesis of calcium hydroxyapatite (Ca10(PO4)6(OH)2 thin films on medical grade stainless steel. Two thin film deposition techniques spin-coating and dip-coating were compared. Surface of stainless steel substrates was modified various ways and impact of substrate surface modification on quality of coatings was evaluated. In addition, in-vitro performance of stainless steel-calcium hydroxyapatite composites in simulated body fluid was investigated. Calcium hydroxyapatite coatings were investigated employing various analytical methods such as XRD, FTIR, XPS, SEM, AFM, Raman and others. Results were summarised in conclusions. |
