Abstract
Studies of the modification of medical agraffe surface by the microarc oxidation method are presented. The scheme and modes of microarc oxidation process are developed for production of biocompatible, homogeneous, porous calcium phosphate coating with desired thickness and surface morphology on the agraffe surface. The coating morphology is represented by spheroidal formations with pores. The coating after deposition has an X-ray amorphous state. Crystalline phases in the coatings are formed during the annealing. The main phase is a double titanium and calcium phosphate, CaTi4(PO4)6. A scheme of the ciprofloxacin covering for titanium agraffes with biocoatings is proposed. The coating thickness and concentration of the initial solution have the most effect on the ciprofloxacin adsorption. Modification of the agraffe surface with deposition of calcium phosphate coating and drug delivery in the coating will make it possible to provide optimal mechanical and biological properties of implants.
