Novel high-temperature-resistant hot inlay material

Abstract

The invention relates to a novel hot inlay material for inlaying of a metallographic sample and relates to composition design and a curing process of a novel hot inlay material. The hot inlay materialconsists of a mixed liquid, aluminate cement and water. The inlay material consists of the following components in parts by mass: 4-5 parts of the mixed liquid, 13-16 parts of the aluminate cement and 1.5-4 parts of the water. The mixed liquid consists of the following components in parts by mass: 1 part of methyl hexahydrophthalic anhydride, 1 part of methyl nadic anhydride, and 3 parts of an epoxy resin. The curing process is carried out for 24-48 hours at 150-160 DEG C. The hot inlay material prepared according to the formula and the curing process is good in forming, high in hardness, high in strength, good in wear resistance, high in deformation resistance at a high temperature, and still hard and non-deformation at 300 DEG C, and in addition, the operation is easy, the cost is low and environmental friendliness is achieved.

Description

technical field [0001] The invention relates to the field of metallographic sample inlay materials, and has the characteristics of high deformation resistance at high temperature, low cost and convenient operation. Background technique [0002] The invention aims to solve the problem that the inlaid material softens during the experiments of electron microscopy and mechanical properties of the micro-sample inlaid at high temperature (≤300° C.). [0003] Inlaid metallographic sample preparation has three functions, the sample is fixed for the adjustment of the observation surface; the sample support is used to support the observation surface during grinding and polishing; the standardized shape is used for easy clamping during grinding and polishing. The hardness and strength of the mounting material remain basically unchanged at high temperature is the prerequisite for electron microscopy and mechanical properties at high temperature. [0004] Thermal mounting material is c...
