Description
Technical Field
The utility model relates to a second phase particle draws the technical field of system appearance in the steel, specifically is a system appearance device of second phase particle in the steel of gathering at the watch glass evenly spreads.
Background
The second phase particles in the steel directly influence the mechanical property and the service performance of the steel, so the quantity, the size, the type and other characteristics of the second phase particles are important indexes for evaluating the quality of the steel. Due to the limitation of the two-dimensional metallographic method on the observation of the second phase particles, the three-dimensional morphology of the second phase particles cannot be accurately displayed, and complete information of the second phase particles is difficult to reflect, so that the second phase particles are often extracted to perform three-dimensional morphology analysis. At present, two ways of chemical erosion (such as acid, halogen-methanol solution and the like) and electrolytic erosion are mainly adopted to dissolve a steel matrix, and second phase particles are collected and observed.
After separating the second phase particles from the steel matrix, the second phase particles are generally purified by elutriation or flotation separation, and then the inclusions are gathered in a collection container for sample preparation. A method for separating inclusion particles from an anode sludge turbid solution by using a petri dish after a steel sample is subjected to non-aqueous electrolytic treatment is described in an article entitled "Extraction, Thermonami catalysis, and Precipitation Mechanism of MnS-TiN Complex Inclusions in Low-Sulfur solids" (Metallurgical and Materials transformations A, 2016, 47(6), 3015-3025). At present, common sample preparation methods include a filtration method and an indirect transfer method, wherein the filtration method is to pass a solution containing impurities through filter paper with a certain aperture, so that the impurities larger than the aperture are remained on the filter paper, and the impurities are observed after carbon spraying; the indirect transfer method is that after the impurities are gathered at the bottom of the container, a clean small rod is used for sticking the impurities onto the conductive adhesive, and the conductive adhesive is spread by the small rod and can be directly sent to an electron microscope for observation. Both methods can achieve the purpose of observing the three-dimensional morphology of the second-phase particles, but the sample preparation process is not easy to control, and a high success rate is difficult to realize to prepare a high-quality sample.
The chinese patent publication CN 85105786, "preparation of ultra-thin sheet for ultra-micro sample", proposes that an electroplating method is used to inlay ultra-micro sample to prepare particle sample with micron order. The method can realize smooth plating of particles on the metal sheet, is convenient for microscopic analysis, but has more complex operation steps and higher requirements on experimental conditions.
