The hardness of metal borides makes them suitable for applications as corrosion resistant coatings and, in combination with other materials, as hard coatings for cutting tools, for example. The plasma induced chemical vapor deposition of Zr(C,B) from the precursor CpZr(BH4)3, where Cp is C5H5-, is described and the results of an investigation of the dependence of the deposition rate and the film characteristics on the deposition parameters, e.g. the carrier gas and the substrate temperature, are presented.
