金属材料FV520 B冲蚀模型的建立与验证
Establishment and verification of an erosion model for metal materials FV520B
摘要
Abstract
In this paper, an erosion model is developed in order to describe the erosion performance of metal materi⁃als FV520B through mathematical methods. The study takes into consideration factors such as erosion environmental factors, properties of the target and particle. It consists of calculation for micro⁃cutting wear and deformation wear of plastic material erosion model. According to the result of orthogonal erosion experiment of metal material FV520B, the model to calculate the erosion rate of FV520B is developed by the regression analysis and variance analysis and single factor erosion experiments are used for comparison testing. The variance analysis results verify that the model is effective in describing the erosion process and the calculated value of erosion rate made by the proposed model is in good agreement with the results of single factor experiments. It also indicates that this calculation model is appli⁃cable and reliable in estimating the erosion rate of metal material FV520B under various working conditions. The re⁃search result can be used to guide evaluation of the life in aspects of erosion and wear of the impeller material FV520B.关键词
