Linear cutting tests in artificial sand-clay mixtures to study the influence of brittleness on abrasive wear of cutting tools
Abstract
Linear cutting tests on an artificial kaolinite clay were performed to distinguish different failure modes during the drying process. The influence of brittleness on abrasive wear of cutting tools was studied by drying an artificial sand-clay mixture. Three different failure patterns were examined: a ductile mode, at which the chip sticks to the cutting blade, a transitional mode and a brittle mode, at which chips were broken off. Brittleness is expected to influence the wear mechanism during cutting: the more brittle the rock or soil, the more three-body abrasion will occur. In ductile material two-body abrasion is expected to be of main importance. Des expériments de coupure linéaire ont été faits sur une argile kaolinite artificielle pour distinguer des modèles de cassure pendant la dessiccation. L’influence de la friabilité sur l’usure abrasive de dents coupantes a été examiné pendant la dessiccation d’un mélange de sable et d’argile artificielle. Trois modèles de cassure différent ont été examinés: Un modèle ductile, où la couche colle au tranchant, un modèle transistoire, et un modèle friable où la couche a été brisé. Il est supposé que la friabilité influence le méchanisme d’usure pendant la coupure: si la friabilité de la pierre ou du sol est plus grande, il y apparaîtra plus d’abrasion tri-corporelle. Quand aux matériaux ductiles, on suppose que l’abrasion bi-corporelle v soit essentielle.
