Problems solved by technology

The characteristic of this similar device is that the load is small and the movement stroke is small. The corrosion potential and corrosion current density are accelerated by electrochemical methods. Due to the strong microscopic characteristics of the research, it is mostly used for research on corrosion and wear mechanisms. And carry out the research on the wear and corrosion of biological materials, and the corrosive medium is liquid, there is no superposition of temperature alternation or light, it is difficult to truly evaluate the corrosion and wear degree of relative moving parts in the marine atmospheric environment, and it is impossible to conduct non-conductive non-metallic materials. Evaluate the corrosion and wear characteristics of materials or inorganic materials

example 1

[0064] Alloy steel sample, the size is Φ80×5mm, the surface is polished by ordinary grinder, and the 6 samples are numbered and placed on the figure 1 In the 6 sample fixtures of the middle sample disk, set the load, the rotational speed of the sample pin on the friction pair and the wear time of each sample, and then start loading to wear the No. 1 sample, stop the movement of the friction pair after 30 minutes, and put the upper The sample pin leaves the No. 1 sample, moves to the top of the No. 2 sample, repeats the above process in turn and transfers to other samples. After 10 cycles, each sample can be removed from the sample holder in turn. A digital camera or a stereo microscope is used to observe the change of the surface reflection before and after the corrosion wear, or the weight change of the sample before and after the test is weighed by a precision balance, and then the sample is re-clamped back to the sample holder, and the next round of corrosion wear is carried...

[0066] Alloy steel sample, the size is Φ80×5mm, the surface is polished by ordinary grinder, the 6 samples are divided into two groups, and they are processed by different heat treatment processes. Number the 6 samples and place them on the figure 1 Among the 6 sample holders in the middle sample tray, samples 1, 2, and 3 are used as one group, and samples 4, 5, and 6 are used as another group. Set the load, the rotational speed of the sample pin on the friction pair and the wear time of each sample, then start loading to wear the No. 1 sample, stop the movement of the friction pair after 30 minutes, and the upper sample pin leaves the No. 1 sample and moves to the No. 2 sample. Right above the number sample, repeat the above process in turn and transfer to other samples. After each sample has gone through 20 cycles, it can be removed from the sample holder in turn, and the corrosion and wear on the surface before and after the corrosion wear can be observed by a digital camer...

Description

technical field [0001] The technical field of data corrosion and wear of the present invention is specifically a marine climate environment-friction load coupling test equipment and test method. Background technique [0002] Corrosive wear refers to the wear phenomenon in which the friction surface and the medium undergo chemical or electrochemical reactions in corrosive media to cause material loss. Under the combined action of corrosion and wear, the loss rate of materials far exceeds the superposition of the material loss rate when corrosion and wear act alone, and a large number of ships and aircraft carriers, carrier-based aircraft, coastal or offshore armored vehicles, turrets, radar Military equipment, offshore oil drilling platforms, ocean-going ships and civilian equipment have long been eroded by the marine climate environment. A large number of rotating bodies or relative moving parts not only have chloride ion corrosion, alternating cold and hot temperature chang...
