Equipment built for mining and construction is held under extreme wear conditions during its entire operation time. Most of the times abrasive wear is the only type of wear considered. No reports or studies on erosive wear were found on the materials selected for the construction of these equipment & machinery.
While choosing materials, surface hardness and mechanical properties are the main factors for the average selection criteria. Tribological properties are scarcely taken into account during material selection, making a huge impact on the overall performance of the equipment.
The results of this erosion wear study were compared along surface hardness and profilometry of the eroded footprint. All the tests were done under the same environmental conditions and the same erosion parameters (counter body velocity, angle of incidence and quantity of erosive medium).
