Abstract

Titanium dioxide (TiO2), which is a hard and corrosion resistant oxide, is used for coating stainless steels and other biomedical metals in order to improve pitting corrosion resistance. Generally, TiO2 based coatings can be produced by various methods like sol-gel and vapor deposition. Moreover, particulates can be deposited with mechanical activation. SPEX is one of the methods that produced coating with mechanical activation and leads to formation of higher process energy for production of homogenous coatings. In this study, titanium dioxide particulates were coated on the AISI 2205 duplex stainless steels by high energy ball milling. Milling process was carried out for 2, 5 and 10 hours. Coated samples were sintered at 500˚C for an hour. Sintered samples were characterized by scanning electron microscopy (SEM), surface roughness and corrosion tests.
