- This study is an experimental investigation of the chemical vapor deposition of titanium diboride on metallic substrates by the hydrogen reduction of TiCl/sub 4/ and BCl/sub 3/ at temperatures between 850/sup 0/C and 1100/sup 0/C. Kovar, tantalum, and several stainless steels were found to be suitable substrates since they could withstand the deposition temperature, had adequate resistance to HCl, a by-product of the deposition reaction, and had thermal expansion coefficients sufficiently close to that of TiB/sub 2/ (less than or equal to10 x 10/sup -6///sup 0/C). The TiB/sub 2/ coatings produced were 68.2% Ti and thus near stoichiometry and had very low impurity content. They had Knoop hardnesses averaging 3300 kg/mm/sup 2/ and exhibited extraordinary erosion resistance.
