Titanium Dioxide MOCVD Coating on CoCr Alloy and its Properties in Compare with Phosphate Coatings

Improving osseointegration of Co-Cr by nanostructured titanium coatings

“…However, lack of osseointegration is limited its application (Okazaki and Gothoh 2005 ; Granchi et al 1999 ; Ingham and Fisher 2005 ). Previous studies have shown that surface modification of Co-Cr by coating their surface with a bioinert material such as diamond-like carbon (DLC) (Choubey et al 2004 ), titanium oxide (TiO 2 ) (Han et al 2009 ; Dicu et al 2008 ) and titanium nitride (TiN) (Pham et al 2011a , b ) would offer improved the osseointegration, supporting bone growth on the Co-Cr implants. Nevertheless, there is a concern about instability of the coating-substrate interface because there are a lot of differences in physical and chemical properties between the coating and the substrates.…”
