| titleOfInvention | A kind of preparation method of the aluminium alloy oil drilling pipe screw joint with insulation and wear and corrosion behavior |
| abstract | The invention discloses a kind of preparation methods of aluminium alloy oil drilling pipe screw joint with insulation and wear and corrosion behavior.This method is to carry out micro-arc oxidation treatment to aluminium alloy oil drilling pipe screw joint, there is the ceramic coating of good wear performance in joint surface in-situ preparation, it is reacted again using siliceous alkyl compound and silane coupling agent and 8-hydroxyquinoline etc. by hydrolysis-condensation and obtains polysilane solution, one layer of organopolysilane coating with corrosion self-healing action is coated in ceramic coating surface by dipping-cured method.This method is by preparing ceramics/organic composite coating on nipple surface, substantially increase the insulation of aluminum alloy joint, wear-resisting and corrosion resisting property, it is able to satisfy corrosion resistance requirement in a corrosive environment after aluminum alloy drill pipe nipple being dismounted for multiple times, and this method simple process, it is low in cost, high production efficiency, production process is environment friendly and pollution-free, is conducive to promote the use of. |
