Problems solved by technology

At present, with the continuous deepening of research on ceramic particle reinforced steel-based wear-resistant composite materials, more and more shortcomings have been exposed in the application process: ceramic particles are used to disperse and evenly distribute in the wear-prone parts of metal materials, and in the equipment or parts. When the wear-resistant composite layer is formed on the part that is easy to wear, the thickness of t

Abstract

Disclosed is a preparing method for casting an inlaid ceramic/metal wear-resisting compound liner. A chemical vapor deposition method is adopted to prepare uniform, continuous and high-purity metal activation coatings on ceramic monomers in various shapes, the kind and the structure of the coatings are changed, wettability between ceramic and metal in the compound process is improved, and the compound quality is improved; finally, through the lost foam casting technology, that is, ceramic reinforcements with the metal activation coatings deposited are fixed into a polystyrene foam model, and casting molding of molten metal is carried out; solid ceramic serves the reinforcements, the ceramic reinforcements are subject to reasonable structural design, and volume fractions and distribution of the reinforcements are controlled; and through forming of the activation coatings on the surfaces of the ceramic reinforcements, the interface combination condition between the ceramic and the metal is improved, operation is simple, easy to implement and low in cost, and the inlaid ceramic/metal wear-resisting compound liner which is good in comprehensive performance and capable of meeting various complex working conditions can be prepared.

Description

technical field [0001] The invention belongs to the field of wear-resistant materials, and in particular relates to a preparation method of a cast inlaid ceramic / metal wear-resistant composite liner. Background technique [0002] Wear-resistant materials are widely used in various industrial fields such as metallurgy, mining, ports, electric power, coal, building materials, etc., with a wide coverage and huge consumption. Many workpieces and equipment fail rapidly due to wear. Abrasion has lost 1 / 3 of the world's primary energy. According to incomplete statistics, my country's annual economic loss due to abrasion is more than 100 billion yuan. Abrasive wear alone will consume more than 3 million tons of metal wear-resistant materials every year. 15% annual growth rate. The development and use of high-life wear-resistant materials are related to the long-term and stable development of the national economy. At present, traditional wear-resistant steel materials widely used a...
