主 题：Micro-arc oxidation Biocoatings Calcium phosphate Wollastonite
摘 要：Investigation results of micro-arc wollastoniteecalcium phosphate(W-CaP)biocoatings on the pure titanium(Ti)and Zr-1wt.%Nb(Zr-1Nb)alloy were *** voltages of 150-300 V generate the micro-arc oxidation(MAO)process with the initial amplitude current of 150-550 A and 100-350 A for Ti and Zr-1Nb substrates,*** identical dependencies of changes of the coating thickness,surface roughness and adhesion strength on the process voltage were revealed for the both *** W-CaP coatings with the thickness of 10-11μm were formed on Ti and Zr-1Nb under the low process voltage of 130-150 *** wollastonite particles with the size in the range of 40-100μm were observed in such *** structure of the coatings on Ti was presented by the X-ray amorphous and crystalline *** X-ray reflexes relating to the crystalline phases of Ti and wollastonite were observed only in XRD patterns of the coatings deposited under 130-200 V on ***,the crystalline structure with phases of CaZr4(PO4)6,β-ZrP2O7,ZrO2,and Zr was detected in the coatings on ***-IRS,XRD,SEM,and TEM data confirmed that the increase of the process voltage to 300 V leads to the dissociation of the *** toxic effect of specimens on a viability,morphology and motility of human adipose-derived multipotent mesenchymal stem cells was revealed in vitro.
