Device for realizing erosion resistance test

Abstract

The invention discloses a device for realizing an erosion resistance test, which is characterized in that a stirrer is driven by a stepping motor to rotate so as to stir an erosion medium on a scraping disc, the erosion medium enters a funnel after being stirred by the stirrer and filtered by the scraping disc, airflow carries the erosion medium to flow out from a powder outlet pipe, then is sprayed out through a nozzle of a spray gun to an erosion sample on a movable sample table. Accurate quantitative supply of the erosion medium can be achieved by adjusting the rotating speed of the stepping motor, and by arranging a second gas inlet pipe provided with a heater, heated gas carries the erosion medium flowing out of the powder outlet pipe to be jetted to the to-be-eroded sample on the movable sample table, the erosion medium sprayed on the to-be-eroded sample is a heated erosion medium, and the erosion resistance test at a specific temperature can be realized, so that the solid particle erosion resistance test of a to-be-detected material from room temperature to high temperature can be met, and the quantitative evaluation of the erosion resistance of the material is realized.

Description

technical field [0001] The invention relates to the technical field of material performance testing equipment, in particular to a device for realizing erosion resistance performance testing. Background technique [0002] Solid particle erosion widely exists in many industrial sectors such as machinery, metallurgy, energy, chemical industry, and aerospace, and has become an important cause of material damage or equipment failure. For example, when an aircraft is in service in a harsh environment, solid particles such as sand, dust, and ice in the air will severely erode the surface of the compressor blades under the action of high-speed airflow, affecting the shape, size and surface finish of the compressor blades , thereby reducing the boosting efficiency of the compressor, resulting in loss of engine performance and shortened life. Therefore, it is of great significance to study how to prevent the erosion failure of materials or equipment and to test the erosion resistance...
