Abstract

The invention relates to a swing type high-temperature friction and wear test device, and belongs to a test device for friction and wear of a material at a high temperature. The device is characterized in that a vacuum cavity and driving modules are fixedly connected with the upper portion of a rack, the driving modules penetrate through the vacuum cavity from the two sides, the top end of a friction and wear module is installed in the vacuum cavity, a swing rod at the lower end is hinged to connecting rods of the driving modules symmetrically arranged on the two sides, and the bottom of a high-temperature loading module is fixed in the vacuum cavity through a bolt and is positioned below the friction and wear module. According to the invention, the device has the advantages that the structure is novel, the friction coefficient of a material in a high-temperature vacuum environment can be obtained, the linear motion of the push-pull rod of the driving module is ensured, the device is safer, the heating efficiency of a plate-shaped test piece is effectively improved, the uniformity of temperature distribution on the plate-shaped test piece is ensured, the accuracy of test data is improved, and the safety of test equipment and testers is protected.

Description

technical field [0001] The invention relates to a performance evaluation device for friction and wear of materials at high temperatures, in particular to a swing-type high-temperature friction and wear test device. Background technique [0002] In the fields of aerospace, automobile manufacturing, new energy, chemical industry, etc., the problem of material wear failure at high temperature is becoming more and more prominent, such as sealing parts for aero-engines, pistons and cylinders of automobile engines, bearings operating in high-temperature environments, and carbonization. Silicon industrial nozzles, etc., high temperature friction and wear are the main failure forms. In addition, various wear-resistant coatings prepared by surface engineering also need to be tested with a friction and wear test device. Therefore, it is necessary to develop a high-temperature friction and wear test device to test the friction and wear properties of materials in a high-temperature envi...
