L’essai de dureté à pour but de déterminer la dureté superficielle des métaux. Il consiste à enfoncer un pénétrateur, dont les formes et les dimensions varient en fonction du type d’essai, dans le métal à tester. La charge est constante et on mesure la surface ou la profondeur de l’empreinte laissée dans le matériau.
