Stress-Electrochemical Corrosion Test Apparatus

Abstract

The invention relates to a stress-electrochemical corrosion testing device capable of realizing the presence of anaerobic bacteria. The device consists of an electrochemical workstation, a stress corrosion stretching machine, a constant temperature water bath and a self-made stretching box. The self-made stretching box is a cylindrical double-chamber structure. Dead, the inner wall has brackets, the height of the inner room is lower than that of the outer room, the box cover is drilled with multiple holes, the gap between the box cover and the box body is sealed with a sealing film, and the outer layer of the stretch box is covered with a layer of cotton cloth tubular heat preservation cover. There are rubber bands at both ends, and two medium solutions can be used in the constant temperature water bath for heating or cooling the test solution. The device can avoid the overflow of the solution in the stretching box, and provide a constant temperature and airtight stress corrosion environment for the tensile sample, and realize the simultaneous measurement of various testing methods.

Description

Technical field [0001] The invention relates to a corrosion test device, in particular to a stress-electrochemical corrosion test device that can simultaneously perform stress corrosion and electrochemical corrosion tests in the presence of anaerobic bacteria. Background technique [0002] At present, the well-known stress corrosion test device consists of a stretching box and a stretching machine. Seal the test piece on the tensile box, put the test solution in the box, close the lid, and fix the entire tensile box on the stress corrosion tensile machine for testing. However, the box body and the box cover of this stretching box are easily separated, and the solution often overflows on the stress corrosion stretching machine, resulting in corrosion of the transmission shaft of the stretching machine. Moreover, the current stress corrosion test equipment can only be performed at room temperature, and anaerobic bacteria are suitable to grow in an anaerobic environment with a cons...
