[0063] example 1:
[0064] Alloy steel samples, the size is Φ80×5mm, the surface is polished by ordinary grinder, and the 6 samples are numbered and placed at the same time figure 1 In the 6 sample clamps of the middle sample plate, set the load, the rotation 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, and stop the friction pair movement after 30 minutes. The sample pin leaves No. 1 sample, moves to the top of No. 2 sample, repeats the above process in turn and transfers to other samples. After each sample undergoes 10 cycles, it can be removed from the sample holder in turn, and passed Use a digital camera or stereo microscope to observe the changes of the surface before and after corrosion and wear, or use a precision balance to weigh the changes in the weight of the sample before and after the test, and then re-clamp the sample back into the sample fixture, and perform the next round of corrosio...

[0065] Example 2:
[0066] The alloy steel samples, the size is Φ80×5mm, the surface is polished by an ordinary grinder, the 6 samples are divided into two groups, and they are treated by different heat treatment processes. After the 6 samples are numbered, they are placed in the figure 1 Among the 6 sample holders in the middle sample tray, No. 1, 2 and 3 are used as one group, and No. 4, 5 and 6 are used as another group. Set the load, the rotation 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. After 30 minutes, stop the movement of the friction pair. The upper sample pin leaves No. 1 sample and moves to 2. Directly above the number sample, repeat the above process in turn and transfer to other samples. After each sample has undergone 20 cycles, it can be removed from the sample fixture in turn, and the surface before and after corrosion and abrasion can be observed through a digital camera or ster...

[0067] Example 3:
[0068] LC4 aluminum alloy samples, the size is Φ60×5mm, 3 samples as a set (numbered 1, 3, 5), the surface is polished by a common grinder, and the 3 samples are polished and anodized. Comparison group (numbered 2, 4, 6), after numbering 6 samples, place them in figure 1 In the 6 sample clamps of the middle sample plate, set the load, the rotation 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, and stop the friction pair movement after 30 minutes. The sample pin leaves No. 1 sample, moves to the top of No. 2 sample, repeats the above process in turn and transfers to other samples. After each sample undergoes 10 cycles, it can be removed from the sample holder in turn, and passed Use a digital camera or stereo microscope to observe the changes in the surface before and after corrosion and wear, or use a precision balance to weigh the changes in the weight of the sample before and af...
