Abstract
(EN)
Provided is an alloy powder which makes it possible to produce structures having high hardness and excellent in terms of wear resistance and operation efficiency. The alloy powder of the present invention comprises Co, Mo, and Fe and is characterized in that when the Co content is 25-35 mass%, the Mo content is 10-17.5 mass% and when the Co content is 35-40 mass%, the Mo content is 7.5-12.5 mass%.
(FR)
L'invention concerne une poudre d'alliage qui permet de produire des structures ayant une dureté élevée et d'excellentes performances en matière de résistance à l'usure et d'efficacité de fonctionnement. La poudre d'alliage de la présente invention comprend du Co, du Mo et du Fe et est caractérisée en ce que lorsque la teneur en Co est de 25 à 35 % en masse, la teneur en Mo est de 10 à 17,5 % en masse et lorsque la teneur en Co est de 35 à 40 % en masse, la teneur en Mo est de 7,5 à 12,5 % en masse.
(JA)
