Abstract

PURPOSE: To enhance the wear resistance of cutting hard tips or tools by mixing hydrocarbon, N2 or NH3 into a higher halide such as HfI4; feeding this mixed gas onto substrates to be coated; and treating them under reduced press. at a specified temp.
CONSTITUTION: I2 9 is kept at a predetermined temp. with thermostats 10, 11 to generate a fixed quantity of I2 vapor. This vapor is fed to heating furnace 7 together with Ar and reacted with Hf 8 at 300W700°C. C4H10 is mixed into the resulting HfI4, and this mixed gas is passed through uniform dispersion plate 12 and contacted to substrates 5 mounted on holders 6 in reaction tube 1 under reduced press. at 850W1250°C. Thus, dense HfC coating tips with superior uniform adherence are obtd. on substrated 5. The tips are superior to conventional ones by several times in cutting performance.
