Constant temperature wiggly corrosive wear testing device and test method thereof

Abstract

The invention relates to a constant temperature wiggly corrosive wear testing device and a test method thereof. A medium cavity of a high ball discharge test piece is arranged on the periphery of a lower clamp of the testing device, and the cavity is filled with test medium; the wall of the cavity is of a sandwich layer structure, the lower part of the sandwich layer is provided with a water inlet, the upper part is provided with a water outlet, the water inlet is connected with a constant temperature water bath kettle by a miniature water pump, and the water outlet is directly connected withthe constant temperature water bath kettle, thereby forming a constant temperature water circulation system; an auxiliary electrode and a reference electrode are immersed in test medium of the mediumcavity; and the auxiliary electrode, the reference electrode and the upper end face of an upper test piece are respectively connected with the corresponding port of a microprocessor controlled electrochemical workstation by conducting lines so as to form an electrochemical corrosion test system. The testing device and the method thereof can conveniently wear materials in the constant temperature test medium by wiggly corrosion, thereby much more factually and accurately testing the wiggly corrosive wear property of the materials in the specific corrosion medium; and the testing device and themethod thereof provide much more accurate and reliable test basis for corresponding design, so that the properties and the service lives of equipment and apparatus can be increased.

Description

technical field [0001] The invention belongs to the technical field of wear and corrosion, in particular to a corrosion wear test device and a test method thereof. Background technique [0002] The three main ways in which materials or equipment are damaged and fail are wear, corrosion and fatigue. Wear is the damage of material loss and dimensional change caused by relative frictional movement between contact pairs; corrosion is the material or equipment under the action of surrounding corrosive media (most commonly liquid and gas), due to chemical changes Damage caused by electrochemical changes or physical dissolution; and fatigue is a form of damage that produces cracks until fracture under alternating loads. Since most materials or equipment work in a certain corrosive medium, there is corrosion phenomenon in the process of wear and fatigue. The wear and fatigue at this time can be called corrosion wear (or corrosion wear) and corrosion fatigue respectively. There is ...
