Problems solved by technology

[0002] The observation of the microstructure of metal materials generally requires the corrosion of metal samples; depending on the composition of the metal samples, it is necessary to use corrosive agents with different acidities for corrosion. Currently, in the laboratory, this work is done manually, which is not only labor-intensive, but also The efficiency is low, and it is likely to cause waste of corrosive agents, and also cause over-corrosion. What is more serious is that it is easy to pose a threat to the safety of operators, and there is currently no experimental instrument for metallographic corrosion

specific Embodiment approach 1

[0027] Combine below Figure 1-3 Describe this embodiment, a metal sample corrosion test device, including alcohol dropper 8, corrosion liquid dropper 11, Z-axis lifting knob 12, lifting motor 14, turntable 15, traverse motor 16, box body 21, objective lens 24. Traversing mechanism 27, rotating wiping motor 28, lifting mechanism 29, connection block 30 with pressure sensor inside, wiping rod 31 and stage, by rationally arranging the steering of turntable 15 and alcohol dropper 8, corrosion liquid dropper 11 and the arrangement of the objective lens 24 can realize functions such as corrosion, flushing, and observation; the present invention realizes functions such as flushing of the metal sample 25, reflux of the corrosion solution, recovery and recycling of the metal sample 25 by rationally setting the layout of the box body 21; the turntable 15 is provided with alcohol dropper 8, corrosion liquid dropper 11 and objective lens 24, and turntable 15 is rotatably connected on the...

specific Embodiment approach 2

[0029] Combine below Figure 1-3 This embodiment will be described. This embodiment will further describe the first embodiment. The alcohol dropper 8, the corrosive liquid dropper 11 and the objective lens 24 are arranged on the turntable 15 in a circular shape with the rotation axis of the turntable 15 as the center line. The distance from the object lens 24 to the centerline of rotation of the rotating disk 15 is equal to the distance from the alcohol dropper 8 to the centerline of rotation of the rotating disk 15, and the distance from the object lens 24 to the centerline of rotation of the rotating disk 15 is equal to the center of rotation of the corrosion dropper 11 to the rotating disk 15 line distance; when the turntable 15 rotates around its own axis, the turntable 15 can only rotate in the path of corrosion dropper 11→alcohol dropper 8→objective lens 24 and objective lens 24→alcohol dropper 8→corrosion dropper 11 , cannot be turned over.

specific Embodiment approach 3

[0031] Combine below Figure 1-3 Describe this embodiment mode, this embodiment mode will further explain Embodiment 2, the metal sample corrosion test device also includes a flushing water backflow hole 1, a water tank 2, a first peristaltic pump 3 and a universal water nozzle 4, and the flushing water backflow The hole 1 is set at the bottom of the tank main body 21, the first peristaltic pump 3 and the water tank 2 are connected through a tube, the first peristaltic pump 3 and the universal water nozzle 4 are connected through a tube, and the universal water nozzle 4 is set in the tank main body 21 , the flushing water return hole 1 is connected to the water tank 2 through a pipe; the electric control box 22 is electrically connected to the first peristaltic pump 3, and the electric control box 22 can realize the metal sample 25 by controlling the start of the first peristaltic pump 3 For flushing, the flushing water flows back to the water tank 2 through the flushing water r...

Abstract

The invention relates to a test device, more specifically a metal sample corrosion test device, including an alcohol dropper, a corrosion dropper, a Z-axis lifting knob, a lifting motor, a turntable, a traverse motor, a box body, an objective lens, The traversing mechanism, the rotating wiping motor, the lifting mechanism, the connection block with the pressure sensor inside, the wiping rod and the stage can achieve corrosion by rationally arranging the steering of the turntable and the arrangement of the alcohol dropper, corrosion dropper and objective lens. , flushing, observation and other functions; the present invention realizes the functions of flushing of metal samples, reflux of corrosion solution, recovery and recycling of metal samples by rationally setting the layout of the main body of the box, and provides an experimental instrument suitable for metallographic corrosion, avoiding Manual direct operation will not pose a safety threat to the operator, and the experimental instrument has high working efficiency, and will not cause waste of corrosive agent and over-corrosion.

Description

technical field [0001] The invention relates to a test device, in particular to a metal sample corrosion test device. Background technique [0002] The observation of the microstructure of metal materials generally requires the corrosion of metal samples; depending on the composition of the metal samples, it is necessary to use corrosive agents with different acidities for corrosion. Currently, in the laboratory, this work is done manually, which is not only labor-intensive, but also The efficiency is low, and it is likely to cause waste of corrosive agents and over-corrosion. What is more serious is that it is easy to pose a threat to the safety of operators, and there is currently no experimental equipment for metallographic corrosion. Contents of the invention [0003] The purpose of the present invention is to provide a metal sample corrosion test device, which can provide an experimental instrument suitable for metallographic corrosion, avoid manual direct operation a...
