摘要: This study is focused on enhancing surface characteristics of AZ91 alloy with the microarc oxidation (MAO) method and bringing in antibacterial susceptibility to it. It aimed bring effect silver (Ag) magnesium base materials covered MAO method. The structural chemical compositions coating were analysed by using XRD, SEM, EDS. In order analyse susceptibilities bacteria adhesions, are marked crystal violet efficacy tests. Susceptibility coatings Staphylococcus aureus (S. aureus-ATCC 29213) having high adhesion analysed. study, it concluded that silver-containing have a lot poor bacterial than silver-free coatings, noncoated samples very strong susceptibilities. When antimicrobial activity coated electrolyte evaluated (zone diameter ∼40 mm), found as sensitive. Antimicrobial medium-sensitive ∼15 mm), uncoated observed form any zones against infection.
