Mesure de la dureté avec un indenteur Vickers. (a) configuration expérimentale. F représente la direction d’application de la contrainte d’un indenteur pyramidal (faces à 68° de la normale) contre la surface ; (b) Photographie en microscopie optique d’un indent Vickers sur un verre de silice où l’on peut observer les deux diagonales ; (c) schéma idéalisé de l’indent et des diagonales à mesurer.
Hardness measurement with a Vickers indenter. (a) experimental setup. F represents the direction of application of the stress of a pyramidal indenter (faces at 68° from the normal) against the surface; (b) Optical microscopy photograph of a Vickers indent on a silica glass where the two diagonals can be observed; (c) idealized diagram of the indent and the diagonals to be measured.
