Abstract

The invention discloses an electrochemical on-line test electrode under high hydrostatic pressure and belongs to the field of measurers. The electrode comprises a test electrode, a fixed pressing cap, a metal sleeve, an electrode fixing sleeve, an insulating top cap, a wiring metal electrode, a first insulating O-shaped sealing ring, a conical sleeve, a metal connector and a second insulating O-shaped sealing ring. Peripheral equipment comprises a high-pressure kettle. The electrochemical on-line test electrode can monitor the corrosion behavior of a material under a simulated deepwater environment in real time and on line in a laboratory, so that the problems of long test period, single data, high cost and the like of an actual deepwater test are solved.

Description

Technical field [0001] The invention relates to an electrochemical online test electrode under high hydrostatic pressure, in particular to an electrode for conducting various electrochemical tests online in a simulated deep sea environment, and relates to a monitoring electrode for the corrosion behavior of materials in a deep sea environment, belonging to a measuring instrument field. Background technique [0002] There are abundant natural resources such as oil and natural gas in the ocean. Exploiting these resources requires a large number of mother ships, underwater robots, transportation pipelines and other instruments and equipment, many of which need to be operated in a deep sea environment below 200m, which is inevitable The ground encounters the corrosion problem of materials in the deep sea environment. Since the 1960s, developed countries such as the United States, Russia, and the United Kingdom have successively carried out research on corrosion of materials in deep ...
