Abstract
Novel implants based on metallic alloys (stainless steel 316 LVM, Ti6Al4V ELI and Ti6Al7Nb alloys) prepared by self-developed method of surface modification are presented in this study. Implants were coated with biodegradable and bioresorbable layer of poly(glycolide-co-caprolactone). Next, half of the perpetrated specimens was subjected to radiation sterilization. After that, samples were divided in to two groups: I - initial state (samples with sterilized “S” and nonsterilized polymer “NS”; II - samples with sterilized “S90” and non-sterilized polymer coating “NS90” after 90 days of exposure to artificial urine. As a result of the conducted research, it was found that after long-term exposure the polymer degradation was even and inconsiderable. However, reduction of adhesion and finally, retraction of the coatings on the titanium alloys has been observed. Moreover, the influence of sterilization process on the kinetics of metallic ion release to corrosion environment for all metallic biomaterials has been observed.
