Witryna24 mar 2024 · Key strategies on the improvement of material wear resistance are generally centered in surface engineering and matrix strengthening. A careful modification of the structure and composition of a surface helps to obtain high wear resistance of the surface layer compared to that of the substrate. WitrynaIt is highly probable that the mechanical properties of the ground increase with depth, hence, the derived surface could present a higher FoS. Once an engineer selects a valid failure surface, its stability is assessed. If the FoS of that surface is adequate then no measures are required.
