Abstract
(EN)
In a method for manufacturing a metal member according to one embodiment, a recess (11) formed in a metal substrate (10) is filled with a mixed powder (20a) in which a metal carbide powder and a metal powder are mixed. A hard layer (20) is formed in the recess (11) using a discharge plasma sintering method by applying pressure to the mixed powder (20a) with which the recess (11) is filled while electrically applying heat.
(FR)
Dans un procédé de fabrication d'un élément métallique selon un mode de réalisation, un évidement (11) formé dans un substrat métallique (10) est rempli d'une poudre mixte (20a) dans laquelle une poudre de carbure métallique et une poudre métallique sont mélangées. Une couche dure (20) est formée dans l'évidement (11) à l'aide d'un procédé de frittage par plasma à décharge par application d'une pression sur la poudre mélangée (20a) avec laquelle l'évidement (11) est rempli tout en appliquant électriquement de la chaleur.
(JA)
一実施の形態に係る金属部材の製造方法では、金属炭化物粉末と金属粉末とを混合した混合粉末(20a)を金属基材(10)上に形成された凹部(11)に充填する。放電プラズマ焼結法を用いて、凹部(11)に充填された混合粉末(20a)を通電加熱しつつ加圧することによって、凹部(11)に硬質層(20)を形成する。
