Study on iron-based diamond bit by DC-electroplating method
(0) Iron-plating technology used for restoration of axis parts was applied to the manufacture of diamond bits in this paper. The technology for electroplating diamond bit of iron matrix was mastered through repeated experiments and research. The productive practice indicated that the DC-electroplated iron matrix of diamond bit has high hardness and good diamond exposure ability;the drilling rate of electroplated iron-based diamond bit was 2 m/h when drilling in grade 9 granite and bit life can reach 44 m, which can satisfy the drilling production requirements.
