Embodiment 1

[0037] The preparation method of the high-purity aluminum metallographic sample of the present embodiment comprises the steps:

[0038] (1) Sampling

[0039] Use wire cutting equipment to cut 15mm*15mm*15mm high-purity aluminum as a sample, and the surface that needs to be metallographic is required to be flat and have no obvious concave-convex shape;

[0040] (2) mark

[0041] Mark the end face (C) and surface (S) that need to observe the metallographic phase in the sample as the grinding surface of the sample;

[0042] (3) Grinding

[0043] Grind the grinding surface of the sample on the grinding disc of the polishing machine, press the grinding surface of the sample on the 320# water-based sandpaper in turn, move in the radial direction and rotate in the opposite direction to the rotation direction of the grinding disc, so that the coarse grinding marks disappear completely, and Consistent fine grinding marks;

[0044] (4) Coarse throwing

[0045] Rotate the sample obt...

Abstract

The invention provides a preparation method of a high-purity aluminum metallographic sample, and relates to the technical field of aluminum metallographic sample preparation. The preparation method of the high-purity aluminum metallographic specimen comprises the following steps: (1) sampling; (2) marking; (3) grinding; (4) rough polishing; (5) fine polishing; (6) electrolytic polishing; and (7) anode film coating. According to the technical scheme, electrolytic polishing is adopted in the polishing stage of the high-purity aluminum, electrolytic corrosion is adopted in the corrosion stage, compared with a traditional method for preparing the metallographic sample through manual and mechanical polishing, time is saved, the efficiency is high, simplicity and reliability are achieved, the prepared metallographic structure is clear and visible, and experiment reproducibility is high.

Description

technical field [0001] The invention relates to the technical field of aluminum metallographic sample preparation, in particular to a method for preparing a high-purity aluminum metallographic sample. Background technique [0002] High-purity aluminum has low deformation resistance, high electrical conductivity and good plasticity, etc. It is mainly used in scientific research, electronics industry, chemical industry and manufacturing high-purity alloys, laser materials and some other special purposes. High-purity aluminum refers to aluminum with an Al content ≥99.999% (5N), which has better conductivity, ductility, reflectivity and corrosion resistance than primary aluminum. In the electronics industry, it is used to make high-voltage capacitor aluminum foil, high-performance wires, and bonding wires for integrated circuits; in the aerospace industry, high-purity aluminum is used to develop and make plasma sails (the latest power to drive spacecraft); in high-speed rail tra...
