Abstract

The invention relates to a metallographic sample chemical immersion corrosion instrument, which comprises a box body, a sample flushing system, an electronic control system, a sample clamping mechanism and a corrosive liquid dropper. Specifically, the box body comprises a base and a cover arranged at the upper end of the base; the sample flushing system comprises a flushing water tank, an electronic control pump and a water spray pipe; the electronic control system comprises a controller and a control panel; and the sample clamping mechanism comprises a support rod, a lifting rod, a trapezoidal block seat, two trapezoidal blocks, and a stop screw. Compared with the manual corrosion way, the metallographic sample chemical immersion corrosion instrument provided by the invention saves labor, improves the corrosion efficiency, reduces the metallographic sample making time and cost, also ensures the corrosion quality, avoids the risk of corrosive liquid damage to operation staff, and solves the sample over-corrosion problem.

Description

technical field [0001] The invention belongs to the technical field of corrosion test instruments for metallographic samples, in particular to a chemical immersion corrosion instrument for metallographic samples. Background technique [0002] The observation of the microstructure of metallographic materials usually requires corrosion of metallographic samples. Metallographic samples with different compositions need to be corroded for different times with etchant of different compositions. At present, in the laboratory, this work is usually done manually, which is not only labor-intensive and inefficient, but also easily causes over-corrosion, so it is urgent to control the corrosion time. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a chemical immersion corrosion instrument for metallographic samples. [0004] In order to achieve the above object, the metallographic sample chemical immersion co...
