Embodiment 1

[0021] Embodiment 1 of the present invention provides a low-cost porous titanium alloy metallographic polishing reagent, including a reagent composed of zirconia powder, yttrium oxide powder or a mixture of zirconia powder and yttrium oxide powder in any mass ratio mixed with water In this reagent, the mass ratio of zirconia powder, yttrium oxide powder or a mixture of zirconia powder and yttrium oxide powder to water is 2:10.

[0022] Further, the particle size of the zirconia powder or the yttrium oxide powder is not greater than 1 micron.

Embodiment 2

[0024] Such as figure 1 As shown, the second embodiment of the present invention provides a low-cost porous titanium alloy metallographic polishing process, comprising the following steps:

[0025] Taking TC4 as a sample, it was metallographically polished.

[0026] Step S1, rough polishing: use 320-mesh, 800-mesh, 1500-mesh and 2000-mesh sandpaper to polish the sample in sequence, and the grinding speed should not exceed 300rpm. It is required that the scratches of the latter grinding process completely cover the scratches of the previous grinding process;

[0027] Step S2, fine polishing: use silk velvet polishing cloth for polishing, the rotation speed does not exceed 300rpm, configure hydrogen peroxide solution at a ratio of 1:1, during the polishing process, add hydrogen peroxide solution and low-cost porous titanium alloy metallographic polishing to the sample Reagent, polish lasts 15 minutes.

[0028] Further, in the step of rough polishing, the duration of polishing ...

Abstract

The invention is applicable to the technical field of metallographic polishing, and provides a low-cost porous titanium alloy metallographic polishing reagent and a polishing technology.The low-cost porous titanium alloy metallographic polishing reagent comprises zirconium oxide powder, yttrium oxide powder or a reagent formed by mixing a mixture of the zirconium oxide powder and the yttrium oxide powder in any mass ratio with water, and the reagent is easy to prepare, low in cost and suitable for industrial production. The invention further provides a low-cost porous titanium alloy metallographic polishing technology, during rough polishing, deformation twin crystals can be avoided by limiting the polishing rotating speed, and during fine polishing, the low-cost porous titanium alloy metallographic polishing reagent is used, so that the corrosion effect is not affected, and the corrosion effect is not affected. And during polishing, the metallographic observation surface is not colored, the corrosion effect is not affected, the technological process is simple, the application range is wide, and the method is not limited to titanium alloy.

Description

technical field [0001] The invention belongs to the technical field of metallographic polishing, and in particular relates to a low-cost porous titanium alloy metallographic polishing reagent and a polishing process. Background technique [0002] Metallographic structure analysis is the basis for studying the properties of metals and alloys, and plays a very important role in this research field. Metallographic microscopes can zoom in to observe the microstructure, and are extremely important tools for practitioners to study the microstructure of metals. In order to obtain the required metallographic structure diagram, there are roughly five steps, sampling, inlaying, grinding, polishing, and corrosion. Nowadays, mechanical polishing has been implemented in China, that is, it is enough to set the input parameters, but most of the metallographic work is still mainly manual polishing. And in all metal elements. The metallographic preparation of titanium alloys is difficult, ...
