Fabrication and bioresorbability of Ag- and Ta-containing amorphous calcium phosphate films formed on titanium substrates by RF magnetron sputtering

Silver (Ag)- and tantalum (Ta)-containing amorphous calcium phosphate (ACP) coating films were fabricated on titanium substrates by radiofrequency magnetron sputtering for biomedical applications. The sputtering targets were hot-pressed into 10 mol% Ag-containing ß-tricalcium phosphate sintered comp...
