TiO2 nanofilm is known to have good hemocompatibility for that reason is indicated to build cardiovascular devices. When the device involves movable pieces, an important requirement is to be wear resistant. In this work, the wear resistance of TiO2 nanofilm synthetized by the sol-gel dip- coating technique coating Ti6Al4V and 316 Stainless steel was determined. The wear test was performed in a reciprocating wear machine at loads ranged between 10 and 100 mN at a frequency of 30 Hz using a diamond tip as counterface. The influence of the roughness, type of substrate and nanofilm thickness obtained by multiple layers was analyzed.
