[0002] Ni3Al / Si3N4 / SiC composite coating is a material with excellent high-temperature friction and wear performance, which is widely used in aerospace, energy, chemical industry and other fields. In order to evaluate the performance of this composite coating, it is necessary to use a friction and wear tester for testing. When the tester is testing, in order to prevent the material to be tested from sliding sideways, the material needs to be fixed by a clamp. There are some problems in fixing the sample with the existing clamp. For example, in the Chinese patent with the publication number of "CN 216816265 U", a multifunctional sample clamp for a friction and wear tester is disclosed. When the device fixes the material, the base is installed on the body of the friction and wear tester by bolts, and the sample is placed between six clamping blocks. According to the size and shape of the sample, the position of the clamping block is adjusted through the long hole, and then the clamping block is fixed on the upper clamp body by the locking screw, so as to clamp the sample. Therefore, when the clamp fixes the material, the personnel need to rotate multiple fixing structures, which is difficult to fix and has low fixing efficiency. Utility Model Content
