Technical Field

Background
The corrosion and abrasion phenomenon widely exists in mechanical equipment in the industrial fields of petroleum, chemical industry, coal mine, electric power, metallurgy and the like, and is one of main reasons for causing material loss and equipment failure. The corrosion abrasion refers to the phenomenon that the surface material and the surrounding medium react chemically or electrochemically during the relative sliding process of the friction pair dual surface, and the material loss is caused by the mechanical action. In practical working conditions, the corrosion and abrasion are often limited by the influences of material factors, electrochemical factors, mechanical factors, environmental factors and the like. In order to prolong the service life of the part in a severe environment, the failure mechanism of the part under a real working condition needs to be ascertained, so that a theoretical basis is provided for material selection or part structure design, and the service life of the part is prolonged. At present, a laboratory simulation acceleration method is generally adopted for researching a material failure mechanism.
When a laboratory performs a simulation acceleration method, a wear testing machine needs to be matched with a clamp, generally one clamp can only be matched with one friction wear testing machine, and the clamp matched with the corrosion wear testing machine is not available at present, for example, CN209182144U discloses a friction wear testing clamp capable of clamping rectangular pieces, which can only be applied to common friction wear tests and cannot be applied to corrosion wear tests, and can only clamp rectangular samples; in addition, the self-contained upper sample clamp of the friction and wear testing machine at present has no function of matching electrochemical use.
