Abstract: TiB2 and TiN films were coated by chemical vapor deposition on SKD 61 steel to improve the corrosion resistivity of a diecasting machine in a melted aluminum alloy. The protectivity of the film in the melted aluminum alloy was examined by an immersion test at 900°C and a thermal cycle test between room temperature and 900°C. TiN film, which serves as a binder, greatly improves the adhesion of TiB2 film on the steel substrate. The thermal cycle test indicated that the optimum thickness of TiB2 and TiN layers is at 4 and 6μm, respectively. Compared to ion-nitrized steel, steel coated by TiB2/TiN exhibits significantly higher degree of corrosion resistivity.
