Abstract
In this work a microporous oxide layer was formed on two phase (alpha+beta) Ti-6Al-7Nb titanium alloy by the micro-arc oxidation process in an electrolyte containing (CH3COO)(2)CaH2O and Na3PO4. The thickness of the surface layer was in the range of 2.7 mu m-3.6 mu m. Microstructure of the surface layer and the substrate alloy was characterized with use of scanning- and transmission electron microscopy as well as by X-ray diffractometry. The microstructure of the surface layer consisted of TiO2 rutile and anatase nanocrystals as well as of amorphous regions containing mainly Ti, Ca and O atoms and a minority of P, Al and Nb ones. The surface layer was highly porous. The open pores, with diameter up to 6 mu m, were homogenously distributed in the specimen surface. Electron tomography was used to investigate the pores morphology and spatial distribution. It was found that open pores exhibited a complex geometry. The closed pores had nearly spherical shape. Adhesion of the surface layer to the titanium alloy substrate was investigated by means of the scratch-test. The value of critical load L-C2=14 N indicates a good layer adhesion to the underlying substrate. (C) 2013 Politechnika Wroclawska. Published by Elsevier Urban & Partner Sp. z o.o.
