Crystallization of carbides with high hardness in the matrix was proved to be effective to improve erosive wear characteristics under high temperature conditions. In the present study, molybdenum (Mo) with the ability to increase hardenability was added into high chromium cast iron. Erosive wear characteristics of six kinds of materials with 16, 26 mass % chromium (Cr) and 0, 1, 3 mass % Mo content...
Comparing to the carbide-forming elements such as chromium (Cr), molybdenum (Mo) and tungsten (W), nickel (Ni) has a feature of preferentially dissolved into the matrix instead of forming carbides. The carbide-forming elements which were suppressed to dissolve into the matrix would then be encouraged to form more carbides. Hence, the improvement of erosive wear performance of the materials can be...
Due to the complex influence of elevated temperatures on the characteristics of a tribological system, severe high temperature sliding abrasion of single phase metals is a unique type of wear. The mechanisms of high temperature sliding abrasion (indentation and grooving of metallic surfaces) are strongly governed by the temperature-dependent interaction between the bulk metal and the abrasive during...
Due to the urgent demand for the development of new materials with high performance and relatively low cost, materials with varying vanadium (V) and chromium (Cr) content were developed by reducing the content of V, Cr and nickel (Ni) in the present study. The erosive wear performance of these materials after heat treatment was investigated at elevated temperatures (873K and 1173K). Alumina spheres...
