Title (EN) ZINC PHOSPHATE-TREATED ZINC-PLATED STEEL PLATE AND PRODUCTION METHOD THEREFOR
(FR) PLAQUE D'ACIER ZINGUÉE TRAITÉE AU PHOSPHATE DE ZINC ET SON PROCÉDÉ DE PRODUCTION
(JA) リン酸亜鉛処理亜鉛めっき鋼板及びその製造方法
Abstract:
(EN) The present invention provides a zinc phosphate-treated zinc-plated steel plate having an excellent press moldability, with which mold galling which leads to breakage of the molded article at the time of press molding can be adequately restricted, even when used as automobile parts, which have been seeing moves towards parts integration and more complicated shapes in recent years. Provided is a zinc-plated steel plate having, on at least one side thereof, a zinc phosphate coating film, wherein the zinc phosphate coating film has a deposited amount of 1.0-2.0 g/m2, a Mn content of 3.0-8.0 mass%, and a Ni content of 0.7-1.3 mass%, and the coating film surface has a three-dimensional arithmetic average roughness Sa of 0.05-0.12 µm and a three-dimensional maximum height of surface irregularities Sz of 0.4-0.9 µm. The zinc phosphate-treated zinc-plated steel plate has an enhanced press moldability due to improvement in sliding properties and mold galling resistance, has no unevenness in appearance, and also has excellent coating adhesiveness and post-coating corrosion resistance.
(FR) La présente invention concerne une plaque d'acier zinguée traitée au phosphate de zinc ayant une excellente aptitude au moulage à la presse, avec laquelle le grippage du moule qui conduit à la rupture de l'article moulé au moment du moulage à la presse peut être limité de façon adéquate, même lorsqu'elle est utilisée en tant que pièce d'automobile, qui ont connu des évolutions vers une intégration de pièces et des formes plus complexes ces dernières années. L'invention concerne une plaque d'acier zinguée comportant, sur au moins un côté de celle-ci, un film de revêtement de phosphate de zinc, le film de revêtement de phosphate de zinc ayant une quantité déposée de 1,0 à 2,0 g/m2, une teneur en Mn de 3,0 à 8,0 % en masse, et une teneur en Ni de 0,7 à 1,3 % en masse, et la surface du film de revêtement présente une rugosité moyenne arithmétique tridimensionnelle Sa de 0,05 à 0,12 µm et une hauteur maximale tridimensionnelle des irrégularités de surface Sz de 0,4 à 0,9 µm. La plaque d'acier zinguée traitée au phosphate de zinc présente une aptitude au moulage à la presse améliorée grâce à une amélioration des propriétés de glissement et de la résistance au grippage de moule, ne présente pas d'irrégularité d'aspect, et présente en outre une excellente adhésivité de revêtement et une excellente résistance à la corrosion post-revêtement.
(JA) 近年、部品の一体化、形状の複雑化が進む自動車用部品などに用いた場合でも、プレス成形時の成形品のワレにつながる型かじりが適切に抑制される、優れたプレス成形性を有するリン酸亜鉛処理亜鉛めっき鋼板を提供する。 少なくとも片面にリン酸亜鉛系皮膜を有する亜鉛めっき鋼板であって、リン酸亜鉛系皮膜は、付着量が1.0~2.0g/mで、Mn含有量が3.0~8.0mass%、Ni含有量が0.7~1.3mass%であり、皮膜表面の3次元算術平均粗さSaが0.05~0.12μmで且つ3次元最大表面凸凹高さSzが0.4~0.9μmである。このリン酸亜鉛処理亜鉛めっき鋼板は、摺動特性、型カジリ性が改善されて高いプレス成形性を有するとともに、外観ムラがなく、塗料密着性及び塗装後耐食性にも優れている。
