Diamond coatings were deposited onto Mo and WC-Co Substrates using a low pressure premixed acetylene-oxygen flat flame by means of a special apparatus operating at 50 mbar. Uniform diamond coatings containing significant amounts of non-diamond carbon were deposited over areas of approximate to 7 cm(2) onto Mo substrates, the coating thickness after 1 h deposition amounted to approximate to 1 mu m. Upon machining an Al-12 % Si alloy under identical conditions, the diamond coated WC-Co cutting tool inserts showed 30 % less wear than the as-receivcd inserts.
