1304 1305 1308 PDC ball inserts drilling tool blade for oil well drilling
PDC cutters(Polycrystalline Diamond Compacts)are made by sintering micron-sized dia-
mond particles onto a tungsten carbide substrate, with the-characters of high hardness
and wear resistance, which can be widely used-for oil drilling, geographical exploration,
coal mining and machinery-processing, etc.
PDC cutter's characters:
1.high impact toughness and wear resistance,
2.service time is 10~20 times longer than normal carbide materials,
3.easy to-weld;
4.heat stability is good below 650ºC, carbonization will turn up above-750ºC and the impa-
ct toughness and wear resistance will be decreased as-well. So the welding temperature should be kept below 650ºC in order to-ensure the product's service time.
