Embodiment Construction

[0012] The present invention will be described in detail below in combination with specific embodiments.

[0013] The invention discloses a cold processing sample preparation method for a metallographic sample. According to the shape and size of the sample to be prepared, a simple mold is made with a soft material. The soft material can be paper, PVC pipe, etc. In addition, the mold itself It is necessary to ensure that the shape is easy to hold or clamp to facilitate the subsequent detection process.

[0014] Place the sample to be prepared in the center of the mold, and slowly pour the powdered toothbrush powder into the mold so that it completely covers the sample and fills the mold cavity. The height of the mold cavity is 1-1.5cm. Powdered tooth tray powder is generally methyl methacrylate, in the form of fine beads, and its particle size is ≥ 80 mesh.

[0015] Pour in the tray water to make it fully penetrate the tray powder. The powder-liquid ratio of powdered tray powd...

Abstract

The invention discloses a method for preparation of a metallographic sample by cold processing. According to the shape and size of a sample to be prepared, a simple mold is made of a soft material, the sample to be prepared is placed in the center of the mold, and powdered dental base powder is poured into the mold to fully fill a mold cavity, dental base water is poured into the mold cavity, andnaturally solidified, and the processed metallographic sample is obtained after solidification. The method for preparation of the metallographic sample is not limited by the shape and size of the sample itself, has good permeability to the sample with racks and voids, and is simple in operation, and resampling is convenient. The method has low requirements on the sample, and is not limited by theshape and size of the sample, the dental base powder is solidified quickly and steadily, and has excellent permeation capacity for small holes and dents; the prepared sample has sufficient hardness and toughness, and has good acid and alkali resistance; the resampling is easy, and the original sample can be obtained by removing of the dental base powder with an acetone solution.

Description

【Technical field】 [0001] The invention belongs to the technical field of metallographic detection, and in particular relates to a method for preparing a sample by cold working of a metallographic sample. 【Background technique】 [0002] At present, most of the sample preparation of multi-metal samples adopts automatic mounting machine (heating), or directly uses the clamp to hold the sample to prepare the metallographic sample. The traditional method of preparing samples with automatic mounting machines has requirements on the size and shape of the samples themselves. Special-shaped and irregular-sized samples cannot be mounted, and the acid and corrosion resistance is poor; at the same time, the strength of samples prepared by automatic mounting machines is relatively low. high, resampling is difficult. It is simple and easy to use the clamp to hold the sample, but it also has great limitations. It is mainly not suitable for the preparation of small-sized samples. The small...
