Title (EN) MAGNESIUM-CONTAINING METAL MATERIAL PROVIDED WITH COATING
(FR) MATÉRIAU MÉTALLIQUE À TENEUR EN MAGNÉSIUM AVEC FILM DE REVÊTEMENT
(JA) 皮膜付きマグネシウム含有金属材
Abstract:
(EN) Provided is a magnesium-containing metal material provided with, on the surface thereof, a coating having excellent corrosion resistance. Specifically, provided is a magnesium-containing metal material with a coating, characterized by having: a first coating that contains magnesium hydroxide and that is disposed on the surface of a magnesium-containing metal material containing magnesium or a magnesium alloy; a third coating that contains hydroxyl apatite and/or hydroxyapatite carbonate and that is provided above the first coating; and a second coating that contains dibasic calcium phosphate and that is interposed between the first coating and the third coating.
(FR) L'invention fournit un matériau métallique à teneur en magnésium qui possède sur sa surface un film de revêtement doté d'excellentes propriétés anticorrosives. Concrètement, le matériau métallique à teneur en magnésium avec film de revêtement de l'invention est caractéristique en ce qu'il présente un premier film de revêtement contenant un hydroxyde de magnésium à la surface d'un matériau métallique à teneur en magnésium constitué d'un magnésium ou d'un alliage de magnésium, et un troisième film de revêtement contenant une hydroxyapatite et/ou un acide cabronique hydroxyapatite sur ledit premier film de revêtement. En outre, ce matériau métallique à teneur en magnésium avec film de revêtement présente un second film de revêtement contenant un phosphate bibasique de calcium entre ledit premier film de revêtement et ledit troisième film de revêtement.
(JA) 優れた耐食性を有する皮膜を表面上に有するマグネシウム含有金属材を提供する。具体的には、マグネシウムまたはマグネシウム合金からなるマグネシウム含有金属材の表面に水酸化マグネシウムを含む第1の皮膜と、前記第1の皮膜上にヒドロキシアパタイト及び/又は炭酸ヒドロキシアパタイトを含む第3の皮膜と、を有し、前記第1の皮膜と前記第3の皮膜との間に、第二リン酸カルシウムを含む第2の皮膜を有することを特徴とする、皮膜付きマグネシウム含有金属材を提供する。
