Abstract
The invention relates to the field of accelerated corrosion research of nonferrous metal soil, in particular to an accelerated corrosion test device for the nonferrous metal soil. The accelerated corrosion test device is used for detecting and judging the corrosion degree of the soil in a test region to a metal material. A corrosive medium is placed in a conductive capacitor of the device. An upper rubber eraser and a lower rubber eraser are plugged at the upper part and the lower part of a metal pipe respectively. The metal pipe is arranged in the corrosive medium in the conductive capacitor. A direct-current positive terminal is connected to the upper end of the metal pipe and connected with an anode of a direct-current power supply through a lead wire. A direct-current negative terminal is arranged on the outer side surface of the conductive capacitor and connected with a cathode of the direct-current power supply through the lead wire. The corrosion of the nonferrous metal soil is accelerated through an external direct current, thus facilitating quick judge of the corrosion degree of the soil in the test region to the metal material. Related data of metal soil corrosion (weight loss) can be quickly obtained in 24 hours. The accelerated corrosion test device is simple in structure and convenient in measurement, is not limited by regions and is convenient to carry.
