Abstract
Calcium phosphate coating layers were formed by electron beam evaporation of hydroxyapatite as an evaporant with and without simultaneous Ar ion bombardments. The Ca/P ratio of film, which determined the biological properties, was controlled by ion beam current. Without ion beam bombardments, the film had the low Ca/P ratio of 1.30, however, the ratio increased to 2.02 by bombarding of Ar ion beam extracted from the end-hall type ion gun set to 0.6 A. Silver incorporated calcium phosphate films were formed by immersing calcium phosphate coated samples in 0.4 M AgNO3 for 30 min, and the Ag doped surface was almost 100% effective in reducing bacteria on contact with respect to controls.
