Abstract

The invention discloses an element analysis method of a silicon carbide particle reinforced aluminum matrix composite. The preparation method comprises the following steps: dissolving a silicon carbide particle reinforced aluminum-based composite material into a strong alkaline solution; performing evaporating and concentrating at low temperature to obtain a colloidal solution; adding strong oxidant powder into the colloidal solution and uniformly performing stirring; performing oxidation reactions; after oxidation reaction, adjusting the pH value to strong acidity; performing filtering, collecting a filter cake, and performing drying to constant weight, wherein the mass of the dried material is the mass of the silicon carbide; calculating the mass fraction or the volume fraction of the silicon carbide according to the mass of the silicon carbide, fixing the volume of the filtered filtrate to obtain a test sample, and determining the content of other elements except the silicon carbidein the test sample through ICP-AES. According to the method for oxidizing the silicon carbide particle reinforced aluminum-based composite material through the water evaporation temperature, the contents of various elements in the silicon carbide particle reinforced aluminum-based composite material can be smoothly and accurately determined by ICP-AES.

Description

technical field [0001] The invention relates to the field of detection of chemical components of composite materials, in particular to an elemental analysis method for silicon carbide particle-reinforced aluminum-based composite materials. Background technique [0002] Composite materials are composed of two or more materials with different properties, which are composed of materials with new properties in the macro (micro) through physical or chemical methods. Various materials produce synergistic effects in performance, so that the comprehensive performance of the composite material is better than that of the original constituent materials to meet various requirements. [0003] The control and improvement of the properties of silicon carbide particle reinforced aluminum matrix composites are inseparable from the accurate determination of various elemental components in the composites. Inductive Coupled plasma Atomic Emission Spectrometry (ICP-AES for short) analysis techn...
