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.
