Title (EN) HOT-PRESSED MEMBER AND PRODUCTION METHOD FOR SAME
(FR) ÉLÉMENT PRESSÉ À CHAUD ET SON PROCÉDÉ DE PRODUCTION
(JA) 熱間プレス部材およびその製造方法
Abstract:
(EN) Provided are a hot-pressed member having exceptional coating adhesion, and a production method for the same. The hot-pressed member has, on the surface of a steel plate constituting the member, a plating layer containing Zn and Ni, as well as an oxide film overlying the plating layer and containing Zn, the hot-pressed member characterized in that the void formation rate between the plating layer and the oxide film is 80% or less.
(FR) La présente invention concerne un élément pressé à chaud dont l'adhérence de revêtement est excellente, et son procédé de production. L'élément pressé à chaud comprend, sur la surface d'une plaque d'acier constituant l'élément, une couche de placage contenant du Zn et du Ni, ainsi qu'un film d'oxyde recouvrant la couche de placage et contenant du Zn ; l'élément pressé à chaud étant caractérisé en ce que le taux de formation de vide entre la couche de placage et le film d'oxyde est inférieur ou égal à 80 %.
(JA)  塗装密着性に優れた熱間プレス部材およびその製造方法を提供する。 部材を構成する鋼板表面に、ZnおよびNiを含有するめっき層を有し、さらに該めっき層の上に、Znを含有する酸化皮膜を有する熱間プレス部材であって、前記めっき層と前記酸化皮膜との間の空隙形成率が80%以下であることを特徴とする熱間プレス部材。
