Description

Tantalum borides were deposited on a copper substrate from a gas phase TaCl5-BCl3-H2-Ar in the temperature range of 540-8000C. TaB2 (single-phase) was deposited at a source gas flow ratio (BCl3/TaCl5) of six and a temperature above 6000C. On the other hand, TaB (single-phase) was deposited at BCL3/TaCl5 = 2-4 and 600-7000C. The microhardness of TaB and TaB2 were 3250 and 3150 kg/mm2, respectively. The TaB layer was stable to oxidation below 7000C and to acid corrosion. (orig.)
