Abstract
The invention relates to the field of powder metallurgy, and particularly provides a method for improving the hardness of a TiC-Co hard alloy. The method includes the steps that 1,2-butanediol is added into the TiC-Co hard alloy at the adding speed of 120-140 drops/min, and then the mixture is successively subjected to one-step heat treatment andtwo-step heat treatment, wherein one-step heat treatment refers to heat preservation for 20-40 min under 600-650 DEG C, and the two-step heat treatment refers to heat preservation for 30-50 min under 1000-1200 DEG C; then the product is cooled throughliquid nitrogen to 280-320 DEG C, and subjected to heat preservation for 25-35 min; and then the heat treatedTiC-Co hard alloy is prepared after natural cooling. Heat treatment and quenching treatmentare conducted through the method for improving the hardness of the TiC-Co hard alloy, the prepared TiC-Co hard alloy has good wear resistance and toughness, the service life of the alloy is greatly prolonged, and the cost is lowered.
