High-temperature vacuum fretting corrosion-wear test bed

Abstract

The invention discloses a high-temperature vacuum fretting corrosion-wear test bed. The high-temperature vacuum fretting corrosion-wear test bed comprises a rack, a servo motor, a displacement adjustment device, a displacement executing mechanism, a friction force measuring mechanism, a friction pair system, a test force loading mechanism, a lead bismuth alloy cavity, a circulating water way and a vacuum system, the vacuum system is arranged in the interiors of the displacement executing mechanism, the friction force measuring mechanism and the test force loading mechanism, the vacuum system comprises a fusing cavity and a vacuum test cavity, the circulating water way is welded to the outer wall of the vacuum test cavity, a cavity body of the vacuum test cavity is further provided with an inflation valve which can introduce protective gas into the cavity body of the vacuum test cavity, and the fusing cavity and the vacuum test cavity together use a vacuum pumping device and are connected with a pipeline system attached with a heating device; the lead bismuth alloy cavity is filled with lead bismuth alloy, the lead bismuth alloy is melted through the fusing cavity and enters the test cavity, and a lead bismuth alloy testing environment is formed.

Description

technical field [0001] The invention belongs to the technical field of material wear experiments, in particular to a high-temperature vacuum fretting corrosion wear test bench. Background technique [0002] The high-temperature vacuum fretting corrosion and wear test bench is a new generation of computer-controlled test bench, which integrates computer control technology, modular data acquisition communication technology and network technology, and can control the entire test process through the computer, and the system software can control the test The process is monitored in real time, and relevant test parameters and curves are recorded. In the face of increasingly accurate measurement requirements, it is often difficult for existing test benches to perform tests under changing test load, reciprocating frequency, reciprocating stroke, test temperature, friction partner material, hardness and other parameters, as well as the atmosphere environment of vacuum and lead-bismut...

Problems solved by technology

In the face of increasingly accurate measurement requirements, it is often difficult for existing test benches to perform tests under changing test load, reciprocating frequency, reciprocating stroke, test temperature, friction partner material, hardness and other parameters, as well as the atmosphere environment of vacuum and lead-bismuth alloy solution. The fretting wear characteristics and mechanism of materials cannot be accurately judged
