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

Abstract:

Current industrial-hardface reinforcements presentdiverse geometrical shapes, reinforcement-particle size, chemicalcompounds proportions, volume-spatial-distribution, and chemicalcomposition—several kinds of manufactured material types orrecycling ones. Functional Erosion Models, namely, Integral-Differential Models, implement hardness spatial-distributionfunctions to determine accurately the erosion wear magnitude alongthe hardface [Casesnoves, 2016-7]. In previous contributions,several models were simulated/optimized in erosion impact wear overthese hardness differentiable functions—with separated mathematicalanalysis for matrix and reinforcement. This research is focused onextent numerical-computational comparison between two types ofreinforcements manufactured with the same hardface matrix andmanufactured with equal alloy substrate. The simulations, based onlarge laboratory data, are performed from hardface hardness part-distributions to complete/total hardface hardness plottings.Programming software was developed in two kinds of compilators,that is, Freemat and Matlab. Results involve both numerical anduseful graphical determinations for further modellingimplementation. Practical engineering conclusions for erosionfunctional algorithms and accurate tribological models, andrecycling engineering industry, are obtained from the study.
