Embodiment 1

[0032] A preparation method for a cadmium oxide metallographic sample, comprising the following steps:

[0033] (1) Cut the cadmium oxide sample on the cadmium oxide target by wire cutting according to the metallographic sample preparation standard;

[0034] (2) Grind the cadmium oxide sample obtained in step (1) with water-based sandpaper of 400, 800, 1500 and 3000 mesh in sequence: when grinding, fix the sandpaper of a predetermined specification on the electric turntable of the polishing machine, and use pure water as the moistening agent. Wet agent, let the turntable rotate clockwise at a speed of 200r / min, then place the cadmium oxide sample in the direction perpendicular to the wire cutting pattern and the tangent of the electric turntable rotation, and apply 20N vertically downward to the metallographic sample After grinding for 2 minutes, rotate the sample 180°, and then polish it with the same method for 2 minutes; then replace the sandpaper, and rotate the sample 90°...

Abstract

The invention relates to a preparation method of a cadmium oxide metallographic specimen. The preparation method comprises the following steps: (1) cutting out the cadmium oxide specimen on a cadmiumoxide target material by linear cutting according to metallographic specimen preparation standards; (2) mechanically polishing the metallographic specimen obtained in the step (1); (3) carrying out mechanical polishing on the metallographic specimen obtained in the step (2); (4) carrying out chemical corrosion on the metallographic specimen obtained in the step (3); and (5) washing and drying themetallographic specimen obtained in the step (4). The invention also relates to a cadmium oxide metallographic specimen. The corrosive agent used in the method is an ethanol dilute solution of acid, and the defect that the grain boundary cannot be observed due to the fact that cadmium oxide generates white substances in the corrosion process is overcome. Meanwhile, when the same abrasive paper isused for grinding, the sample ground for the first time needs to be rotated by 180 degrees to be ground, and the grinding means can overcome the defect that the metallographic observation is fuzzy dueto the fact that an inclined plane appears in the grinding process.

Description

technical field [0001] The invention relates to the field of metallographic sample preparation, in particular to a cadmium oxide metallographic sample and a preparation method thereof. Background technique [0002] Transparent conductive films are mainly divided into three categories: metal films, oxide films, and other compound films. Among them, oxide films have attracted the attention of many researchers because of their stable performance. Cadmium oxide thin films have become one of the most widely studied oxide thin films in recent years because of their excellent electrical and optical properties. At present, cadmium oxide films are mainly prepared by sputtering cadmium oxide targets, so the performance of cadmium oxide targets has a direct impact on the performance of the films. Grain size and uniformity are one of the important factors affecting target performance. Therefore, it is of high practical value to observe the grain size and uniformity of the target. [...
