Problems solved by technology

In actual operation, even experienced experimenters need multiple attempts and observations to determine whether the degree of erosion is in place, and it takes a lot of time to operate
However, when the amount of detection is too large, the operation time will be accumulated, and it is impossible to operate in batches at the same time

Abstract

The invention discloses a method capable of clearly displaying carbides, which comprises the following steps: grinding and polishing a sample to be detected, pouring a nitric acid alcohol solution into a beaker, and placing the beaker with a magnetic stirrer rotor on a magnetic stirrer; starting a magnetic stirrer, and sequentially putting a plurality of to-be-detected samples with detection surfaces facing upwards into a beaker according to time intervals; finally, washing the taken-out sample to be detected with water, and then washing with oil alcohol; the flushed to-be-detected sample is blow-dried; and placing the to-be-detected sample under a microscope for detection. According to the method, complete and clear carbides are eroded and displayed under the condition that long-time tracking and observation are not needed, and the detection efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of metallographic detection, in particular to a method capable of clearly displaying carbides. Background technique [0002] The existing metallographic testing is to select the correct position of the sample according to GB / T 13298 "Metal Microstructure Inspection Method" and grind and polish the sample to a mirror state, and then according to GB / T 25744 "Carburizing, Quenching and Tempering Metallographic Inspection" requires corrosion to a deep corrosion state, and finally the samples are tested and rated. The principle is mainly to corrode the tissue that does not need to be inspected to black through deep corrosion of the sample, and the carbides cannot be corroded by nitric acid alcohol, so that only the carbides can be seen on the detection surface, which is convenient for detection and rating. However, the existing technical methods only describe the use of nitric acid alcohol for deep erosion, and ...
