| Résumé | In the mining and related industries, the abrasion and impact phenomena operate among the chain of ore processing. While abrasion-corrosion and/or erosion-corrosion phenomena in ore processing are relatively well understood, the concurrent operation of abrasion and impact wear is not well comprehended. The distinctive mechanisms and features of abrasion-impact wear and the synergy, if one exists, between impact and abrasion have not been either explored or discussed systematically in the literature. Furthermore, their economic impact on mining cannot be underestimated especially as past research focused mainly on improving the hardness even at the expense of toughness. Understanding the complex relation between abrasion and impact can efficiently mitigate countless wear problems in mining. The purpose of this paper is to discuss critically the topic, stimulating new questions, and propose some general ideas that might be used as basic guidelines. |
