Titanium Diboride (chemical formula TiB2) is an extremely hard ceramic material (33GPa) with excellent corrosion resistance at high temperatures and very good wear resistance which does not occur naturally in earth. Many TiB2 applications are inhibited by economic factors, particularly the costs of densifying a high melting point material. Current use of this material appears to be limited to specialized applications in such areas as impact resistant armor, cutting tools, crucibles and wear resistant coatings. It is also used as an inoculant to refine the grain size when casting aluminum alloys.
Thin films of TiB2 have a wide range of potential industrial applications due to the wear and corrosion resistance properties that TiB2 can provide to a cheap and/or tough substrate. The electroplating of TiB2 layers possess two main advantages compared with plasma (PVD, CVD) methods: the growing rate of the layer is 200 times higher (up to 5μms−1) and the inconveniences of covering complex shaped products are dramatically reduced.
