Embodiment 1

[0020] A high-temperature in-situ polymerized solid lubricant film friction and wear testing machine, comprising an upper spindle 1, a lower spindle 2 and a high-temperature furnace 7, an upper sample 3 is fixed on the upper spindle 1, and a lower sample 4 is fixed on the lower spindle 2, the upper sample 3 and the lower sample 4 are in contact to form a frictional contact surface, and placed inside the high-temperature furnace 7; the high-temperature furnace 7 is provided with an air inlet channel 5 and an air outlet channel 6, and the gas supply phase The chemical substance enters and exits; the test load is applied on the top of the upper spindle 1, and the lower spindle 2 is driven by a variable frequency motor; a pressure sensor 8 is installed on the upper spindle 1.

[0021] The test selects a pair of Φ10mm ceramic balls in contact with the steel plane; the test load is selected as 500N; the test temperature is selected as 600°C, the accuracy is ±5°C, and it is automatica...

Embodiment 2

[0023] This example is basically the same as Example 1, except that a pair of Φ10mm steel cylinders are selected for the test in contact with a steel plane; the test load is selected as 10N; the test temperature is selected as 150°C, and the accuracy is ±5°C. Automatic adjustment; the sample lubricating film is a preset solid lubricating film, and the test atmosphere gas-phase chemical substances are fed with nitrogen. Under such test conditions, after 5 minutes of the test, there are obvious wear marks on the surface of the steel plane, and the measured friction coefficient of the solid lubricating film ranges from 0.25 to 0.38.

Embodiment 3

[0025] This example is basically the same as Example 1, except that a pair of Φ10mm ceramic balls are selected for the test in contact with the steel plane; the test load is selected as 255N; the test temperature is selected as 375°C, the accuracy is ±5°C, and it is automatically adjusted The lubricating film of the sample is formed in situ to form a solid lubricating film, and the gas-phase chemical substance in the test atmosphere is introduced into a single-component lubricating gas, and the lubricating gas is deposited and reacted at a high temperature to form a solid lubricating film in situ. Under such test conditions, after 5 minutes of the test, wear marks appeared on the surface of the steel plane, and the measured friction coefficient of the solid lubricant film ranged from 0.17 to 0.33.

Abstract

The invention relates to a friction wear test machine for a high-temperature in-situ polymerized solid lubricating film. The machine comprises an upper main shaft, a lower main shaft, and a high temperature furnace; an upper sample is fixed on the upper main shaft, a lower sample is fixed on the lower main shaft, and the upper sample and the lower sample contact with each other to form a friction contact surface, which is placed in the high temperature furnace. The high temperature furnace is provided with a gas inlet channel and a gas outlet channel for in and out of gas phase chemicals. A test load is applied on the top part of the upper main shaft, the lower main shaft is driven by a variable-frequency and variable-speed motor, and a pressure sensor is arranged on the upper main shaft. The test machine can measure important parameters of the solid lubricating film such as friction factor, bearing ability, and lubrication sustaining ability, and a preset solid lubricating film can also be tested by the friction wear test machine at the same time.

Description

technical field [0001] The invention relates to the field of high-temperature friction and wear testing machines, in particular to a high-temperature in-situ polymerized solid lubricating film friction and wear testing machine. Background technique [0002] The purpose of the friction and wear test is to study the phenomenon of material friction and wear and its essence, and to test the tribological properties of various materials. In recent years, with the rapid development of high-tech industries such as automobiles, aviation, and aerospace, the requirements for the tribological properties of materials at high temperatures have become higher and higher, so the methods and equipment for evaluating the tribological properties of materials at high temperatures have also been improved accordingly. [0003] At high temperature, the tribological properties of materials will be very different from those at normal temperature. With the development of industries that require high-t...
