Reciprocating type electrochemical frictional wear experimental instrument and use method thereof

Abstract

The invention relates to material surface friction and wear performance test equipment, to be specific relates to a reciprocating type electrochemical frictional wear experimental instrument and a usemethod thereof. The reciprocating type electrochemical frictional wear experimental instrument comprises a reciprocating machine base, a force measuring machine head and an electrochemical cell. Theforce measuring machine head is connected with the upper part of the reciprocating machine base, a reciprocating mechanism is arranged in the reciprocating machine base, and the reciprocating mechanism is connected with the electrochemical cell, and the electrochemical cell reciprocates along with the reciprocating mechanism. A detection piece is arranged in the electrochemical cell, and the surface of the detection piece is contacted with the force measuring part of the force measuring machine head. The invention is advantageous in that not only all performances of an electrochemical corrosion experiment are guaranteed, but also the electrolytic cell and the reciprocating friction and wear experiment instrument are effectively combined on the basis of no change of the structure and the performance of the reciprocating friction and wear experiment instrument, so that the synchronous operation of two performance experiments is satisfied, the integration of two experimental data is moreaccurate under the condition of inconvenient experimental conditions, and the experimental conditions are closer to actual working conditions.

Description

technical field [0001] The invention relates to material surface friction and wear performance test equipment, in particular to a reciprocating electrochemical friction and wear tester and a use method thereof. Background technique [0002] In recent years, with the advancement of science and technology, the resources of oceans and lakes are constantly being explored, and the materials of human joints have also attracted much attention. These cannot avoid the corrosion and friction of materials, so it is very important to study the corrosion and friction properties of materials. [0003] At present, there are also some testing machines about friction and corrosion on the market, but they are all limited to fretting corrosion friction, or the combination of electrochemical corrosion device and friction and wear testing machine is used for testing, which will not meet the needs of oceans. , lakes and human body fluids for thorough analysis and research on corrosion and frictio...

Problems solved by technology

[0003] At present, there are also some testing machines about friction and corrosion on the market, but they are all limited to fretting corrosion friction, or the combination of electrochemical corrosion device and friction and wear testing machine is used for testing, which will not meet the needs of oceans. , lakes and human body fluids for thorough analysis and research on corrosion and friction, so there are the following shortcomings in the prior art: one is to separate the two experiments of electrochemical corrosion and friction and wear on two instruments, so that the data collection after the experiment is completed There is a deviation from the integration, resulting in a certain deviation between the final result and the real result; the second is to simply combine the two experimental instruments, the equipment detection data is inaccurate, and the data cannot effectively reflect the real performance of the material
