Background technique

At present, in mechanical equipment, there is friction between parts with relative motion. The abnormal friction and wear caused by improper lubrication seriously affects people's production activities and also causes a huge waste of social wealth. Therefore, the research on the tribological properties of wear-resistant materials is very important.

The main problems of this test method are: first, it is impossible to test the relevant friction parameters during the movement; second, when comparing the friction properties of different materials, it is difficult to ensure that their test conditions are the same.

The right end of each said basic base 35 is fixedly provided with a sample holder 31, and the right side wall of each said sample holder 31 is fixedly provided with a said test sample 33; That is to say, there are two test samples 33 in total ;

The basic base 35 is provided with a first pressure sensor 341 on the left side of the sample holder 31, and the basic base 35 is provided with a second pressure sensor 342 on the front side of the sample holder 31;

The pressure detection end of the first pressure sensor 341 is in contact with the left side wall of the test sample 33, and is used to detect the friction force (that is, the tangential friction force) received by the test sample 33 in the horizontal and transverse direction. ;

The pressure detection end of the second pressure sensor 342 is in contact with the bottom surface of the test sample 33 (specifically, the substrate in the test sample 33), and is used to detect the vertical direction of the test sample 33 (that is, the vertical film material). The direction of the top surface) the size of the friction force (that is, the size of the normal pressure, that is, the size of the pressure in the vertical direction);

Therefore, through the first pressure sensor 341, the second pressure sensor 342 and the temperature sensor 36, it is possible to detect in real time and obtain the lateral pressure (the pressure is represented as tangential friction force) and the vertical pressure of the test sample 33 during the test process.

In the friction process, the smaller the friction force is, the lower the friction temperature is, and the material with a small friction coefficient has better friction performance and wear resistance. At the same time, by observing the data changes of pressure and friction, the abrasiveness of the film material and the bonding ability of the film and the substrate can be qualitatively judged. Membrane materials with less pressure first are less wear-resistant. When the friction force has a sudden change during the friction process (for example, the difference between the detected friction force exceeds the preset value), it means that the film material will fall off from the substrate, thereby judging the combination of the film material and the substrate. wear resistance.

In terms of specific implementation, the first pressure sensor 341 and the second pressure sensor 342 are preferably pressure sensors; the temperature sensor 36 is preferably a thermocouple sensor, or an infrared thermometer is directly used.

The numerical values of the lateral pressure (the pressure manifests as tangential friction force) and the vertical direction pressure (the pressure manifests as vertical friction force, which can also be called normal pressure) of sample 33 during the test. Therefore, according to the normal pressure and friction force of the test sample 33 during the grinding process, according to the existing Coulomb friction law, the friction coefficient of the film material can be calculated and obtained. The specific calculation method is similar to the prior art, and will not be described here. .
