The cutting teeth of mining excavation machines need to withstand huge impacts and wear during hard rock excavation. Traditional hard alloy cutting teeth have insufficient toughness and a lifespan of only 300 meters. Replacing one set of cutting teeth requires a 2-hour shutdown, which seriously affects the excavation progress. Daokedao fusion coated WC CoCr composite coating improves the toughness of the coating by adjusting the cobalt chromium content. The impact toughness is ≥ 18J/cm ², and the hardness reaches HRC65, balancing wear resistance and impact resistance. The service life is extended to 1000 meters. After the application of a certain iron mine in Canada, the frequency of tooth replacement has been reduced from 6 times per month to 2 times, the downtime for replacement has been reduced by 64 hours, the excavation efficiency has been improved by 35%, and the cost per kilometer of excavation has been reduced by 40% due to the reduction in tooth consumption and efficiency improvement. The annual direct savings in cutting gear procurement and downtime losses exceeded 2 million US dollars. The mine manager said, 'This technology enabled us to complete the annual excavation task three months ahead of schedule.'.
