Preparation of Titanium Coating on Alumina Foam by Chemical Vapor Deposition

A metal titanium coating was prepared in alumina foam by chemical vapor deposition method. The phase composition of the coating was analyzed by X-ray diffraction (XRD). The coverage of the coating on the alumina foam was analyzed by both optical and scanning electron microscope (SEM) with energy dispersive spectrometer (EDS). The results showed that the obtained titanium coating had a high purity, and showed a good coverage and uniform distribution on the skeleton surface of the foam. The skeleton surface became smooth due to coverage of the tiny holes and cracks by the coating.
