Abstract

The invention provides a high temperature friction wear testing machine, belongs to the technical field of material wear tests, and solves the technical problems that the test precision of the testing machines in the prior art is low and the like. The high temperature friction wear testing machine comprises a frame. The frame is provided with a rotating shaft, and is also provided with a driving device. The top end of the rotating shaft is provided with a tray, the surface of the tray is coated with a thermal insulation layer, and a friction disk is fixed on the surface of the tray. The frame is provided with a bracket, and the bracket is provided with a beam. The beam is provided a force value sensor, and a loading rod is arranged at one end of the beam. A specimen holder is arranged at the bottom end of the loading rod. The high temperature friction wear testing machine comprises a high temperature furnace. The high temperature furnace is provided with a heating cavity, and the bottom end of the loading rod is inserted in the heating cavity. An opening is arranged at the bottom part of the heating cavity, the tray is located out of the opening, and the friction disk is located in the heating cavity. The high temperature friction wear testing machine has the advantages of high test precision and the like.

Description

technical field [0001] The invention belongs to the technical field of material wear testing, and relates to a high-temperature friction and wear testing machine. Background technique [0002] With the continuous development of science and technology, the traditional single material can no longer meet the needs of development. Therefore, many researchers gradually shift their research focus to material science and material processing, through quenching, carburizing, nitriding, cryogenic treatment, Various methods such as solid solution strengthening can be used to improve the performance of materials. As a method of modifying the surface of materials or preparing a new material layer on the surface for specific purposes, surface technology has been widely used in the field of material science and technology. For example, the scheme of preparing TiC ceramic film on the surface of carbon steel by using double-glow plasma technology can obtain a ceramic film with certain wear ...
