Stirring impeller machining drill bit for submersible stirrer
The invention discloses a stirring impeller machining drill bit for a submersible stirrer. The drill bit comprises a drill bit body, the surface of the drill bit body is coated with an anti-oxidationcoating, and the drill bit body is prepared from, by weight, 20-40 parts of expanded vermiculite, 10-20 parts of nanometer silicon nitride, 0.1-2 parts of nickel, 0.1-2 parts of antimony, 15-25 partsof xonotlite, 0.5-2 parts of yttrium, 10-20 parts of thermally decomposed graphite, 1-15 parts of steel fibers, 0.1-1.5 parts of cobalt, 1-10 parts of sodium silicate, 1-5 parts of dimethyl silicone oil and 5-15 parts of a nanometer mesoporous molecular sieve. The drill bit has the advantages of resistance to oxidation and corrosion, high hardness, resistance to abrasion, small grinding force, good self-sharpening performance, high grinding efficiency and long service life.
