Abstract

The invention discloses an automatic erosion experiment device, which relates to the technical field of erosion experiments on workpieces and coating surfaces. In the present invention, the C51 single-chip microcomputer is used as the core processor, the keyboard is used as the input terminal, and the liquid crystal display screen is used as the display window of the operation terminal to realize the control of three stepping motors, thereby controlling the erosion distance, erosion angle, erosion time and Erosion gas pressure. The liquid crystal display simultaneously displays the erosion experiment parameters. Advantages: simple structure, environmentally friendly design, friendly human-computer interaction interface, easy operation, and low cost; using backlash-free ball screw, worm gear drive, and stepping motor control, the equipment has strong reliability and high precision.

Description

technical field [0001] The invention relates to the field of erosion experiments, in particular to an automatic erosion experiment device for testing the erosion resistance performance of workpieces and coating surfaces. Background technique [0002] Erosion phenomenon widely exists in many fields such as machinery, petrochemical industry, aerospace, etc., and has become one of the important reasons for material damage or equipment failure. Erosion wear refers to a material loss phenomenon or process caused by the impact of liquid or solid on the material surface with loose small particles at a certain speed or angle. Generally, it can be divided into airflow sandblasting type erosion and liquid flow or water drop type erosion. The present invention is only aimed at the airflow sandblasting type erosion wear test. Sandblasting erosion is the erosion caused by the impact of solid particles carried by the airflow on the solid surface. This type of erosion wear is the most co...
