2D Computational-Numerical Hardness Comparison between Fe-Based Hardfaces with WC-Co Reinforcements for Integral-Differential Modelling

摘要

Current industrial-hardface reinforcements present diverse geometrical shapes, reinforcement-particle size, chemical compounds proportions, volume-spatial-distribution, and chemical composition - several kinds of manufactured material types or recycling ones. Functional Erosion Models, namely, Integral-Differential Models, implement hardness spatial-distribution functions to accurately determine the erosion wear magnitude along the hardface [Casesnoves, 2016-7]. Up to now, several models have been simulated/optimized in erosion impact wear over the hardness differentiable functions - with separated mathematical analysis for matrix and reinforcement. This research is focused on extended numerical-computational comparison between two types of reinforcements manufactured with the same hardface matrix and equal alloy substrate. The simulations based on large laboratory data are performed from hardface hardness part-distributions to complete/total hardface hardness plotting. Programming software was developed in two kinds of compilators, namely, Freemat and Matlab. Results are presented in form of both numerical and useful graphical determinations for further modeling implementation. Practical engineering conclusions for erosion functional algorithms and accurate tribological models, and recycling engineering industry, have been obtained in the study.
