The use of a binary TiCr coating 12 as a top layer or an underlayer for corrosion protection on a metallic substrate 10. The substrate can be any one of iron, steel, aluminium or an aluminium alloy, magnesium or a magnesium alloy or brass or copper or Zamak or any die-cast material. The TiCr coating can have a constant composition or can be graded so that the proportion of titanium in the layer increase with distance from the substrate. Further top layers can be formed on the coating. The coating can be formed by CVD or PVD processes and may be further subjected to a thermal treatment such as annealing. |
