Title (EN) HOT-WORKING TOOL AND METHOD FOR PRODUCING SAME
(FR) OUTIL POUR FORMAGE À CHAUD ET SON PROCÉDÉ DE PRODUCTION
(JA) 熱間加工用工具及びその製造方法
Abstract:
(EN) Provided is a hot-working tool having superior seize resistance. The present embodiment of a hot-working tool is provided with a substrate and a plating film. The plating film is formed at the substrate surface. Furthermore, the plating film contains, by mass%, 36-44% of W, the remainder comprising Ni and impurities, and has a Vickers hardness of at least 900. Preferably, the plating film having a Vickers hardness of at least 900 is formed by means of heat treatment at a furnace temperature of at least 350°C and an in-furnace time of no greater than one hour.
(FR) L'invention concerne un outil pour formage à chaud présentant une résistance élevée au grippage. L'outil de formage à chaud comprend un substrat et un film de placage formé sur la surface du substrat. Le film de placage contient 36-44% en masse de W, le reste contenant Ni et des impuretés, et présente une dureté de Vickers d'au moins 900. Le film de placage, présentant de préférence une dureté de Vickers d'au moins 900, est obtenu par traitement thermique à une température de four d'au moins 350°C et une durée dans le four inférieure ou égale à une heure.
(JA)  耐焼付き性に優れた熱間加工用工具を提供する。本実施形態による熱間加工用工具は、基材と、めっき皮膜とを備える。鍍金皮膜は、基材表面に形成される。めっき皮膜はさらに、質量%でW:36~44%を含有し、残部はNi及び不純物からなり、ビッカース硬さが900以上である。好ましくは、900以上のビッカース硬さのめっき皮膜は、350℃以上の炉温及び1時間以内の在炉時間で熱処理されることにより形成される。
