Calcium and Zinc Containing Bactericidal Glass Coatings for Biomedical Metallic Substrates

The present work presents new bactericidal coatings, based on two families of non-toxic, antimicrobial glasses belonging to B(2)O(3)–SiO(2)–Na(2)O–ZnO and SiO(2)–Na(2)O–Al(2)O(3)–CaO–B(2)O(3) systems. Free of cracking, single layer direct coatings on different biomedical metallic substrates (titaniu...

description The present work presents new bactericidal coatings, based on two families of non-toxic, antimicrobial glasses belonging to B(2)O(3)–SiO(2)–Na(2)O–ZnO and SiO(2)–Na(2)O–Al(2)O(3)–CaO–B(2)O(3) systems. Free of cracking, single layer direct coatings on different biomedical metallic substrates (titanium alloy, Nb, Ta, and stainless steel) have been developed. Thermal expansion mismatch was adjusted by changing glass composition of the glass type, as well as the firing atmosphere (air or Ar) according to the biomedical metallic substrates. Formation of bubbles in some of the glassy coatings has been rationalized considering the reactions that take place at the different metal/coating interfaces. All the obtained coatings were proven to be strongly antibacterial versus Escherichia coli (>4 log).
