A Metallographic Sample Mounting Method Facilitating Common Anodization of Multiple Samples

Abstract

The invention discloses a metallographic mounting method convenient for common anodization of a plurality of samples. The method comprises the following steps: 1, connecting alloy samples to be mounted by using a leading wire to obtain an alloy sample group; and 2, placing the alloy sample group in the cabinet of a hot mounting machine, filling the cabinet with fine black bakelite powder to form a fine black bakelite powder layer, tiling crude black bakelite powder to form a crude black bakelite powder layer, adding press cake of the hot mounting machine, and carrying out hot molding on the alloy sample group; or placing the alloy sample group in a cold mounting material, pouring a cold mounting material into the cold mounting die, and allowing the cold mounting material to solidify in order to complete mounting of the alloy sample group. The method has the advantages of simplicity in operation, reasonable design, low device requirements, easy obtaining of auxiliary materials, convenience for high-quality common anodization of the plurality of samples, meeting of sample production and metallographic photographing requirements after mounting ends, and avoiding of the time waste disadvantage of multi-time production the plurality of samples or multi-time anodization after one-shot mounting.

Description

technical field [0001] The invention belongs to the technical field of metal sample mounting, and in particular relates to a metallographic sample mounting method convenient for common anodic oxidation of multiple samples. Background technique [0002] For metal materials, metallographic detection has become an indispensable detection method, and during metallographic detection, some samples will use polarized light method for metallographic observation, such as zirconium alloys and titanium alloys such as Gr4. When these alloys are observed by polarized light, it is necessary to anodize the sample first, which can make the image clearer. For small-scale samples, the preparation of metallographic samples requires mounting. Since the mounting powder does not have conductivity, anodic oxidation usually only oxidizes a part of the sample after the sample is prepared, and some samples are used as anodes. If anodic oxidation cannot occur, it cannot be observed; at the same time,...

Problems solved by technology

For small-scale samples, the preparation of metallographic samples requires mounting. Since the mounting powder does not have conductivity, anodic oxidation usually only oxidizes a part of the sample after the sample is prepared, and some samples are used as anodes. If anodic oxidation cannot occur, it cannot be observed; at the same time, only one sample is prepared at a time, which is time-consuming and wasteful. Even if multiple samples are inlaid at the same time, there is a problem that a part of each sample cannot be anodized.
