Ceramic phase composite metal for anti-corrosion oil pipe identification and preparation method of ceramic phase composite metal

Abstract

The invention relates to the technical field of petroleum drilling engineering identification, in particular to a ceramic phase composite metal for anti-corrosion oil pipe identification, which comprises a matrix, an alloy reinforced phase, a ceramic anti-corrosion phase and a coupling agent, the matrix is low-carbon steel, the alloy reinforced phase is a nickel-chromium alloy or a composite alloy of nickel-chromium and other alloys, and the ceramic anti-corrosion phase is a ceramic anti-corrosion phase. The ceramic corrosion-resistant phase is aluminum oxide series ceramic or composite ceramic of aluminum oxide and other ceramic, the coupling agent is a silane series coupling agent or a composite coupling agent of silane and other types of coupling agents, all the components are mixed and sintered to form an annular composite metal main body, a groove is formed in the surface of the composite metal main body, and the annular composite metal main body is made of stainless steel. And a positioning hole and a glue guide hole are formed in the groove. The composite design of the ceramic corrosion-resistant phase and the alloy reinforced phase is adopted, and the special coupling agent is matched, so that the corrosion resistance and the mechanical property of the mark main body are greatly improved, and the mark main body can tolerate the underground extreme corrosion and high-temperature environment.
