摘　　要：根据磷化膜的形成原理,介绍了油管接箍在磷酸盐溶液中的工艺处理过程和检验方法。该工艺处理技术使油管接箍表面形成不溶于水的磷酸盐薄膜,由于具有微孔结构的磷化膜层与基体结合牢固,具有良好的吸附性、润滑性、耐蚀性、不黏附熔融金属(锡、铝、锌)性及较高的电绝缘性。On the principle of phosphate coating formation,the paper introduces the inspection method and the process procedure of oil pipe coupling in the phosphate solution.The process technology can form the phosphate coating on the surface of oil pipe coupling.As a result of the phosphate coating with micro-holes structure combining with the component,and with better adsorbility,lubricativity,causticity,non-adherency molten metals (Stannum,Aluminum,Zinc,etc)and high electrical insulating property,the anti-corrosion of the oil pipe couplings is improved highly.
