Title (EN) MAGNESIUM ALLOY PHOSPHATING AGENT, METAL COMPONENT, AND SURFACE PHOSPHATING TREATMENT METHOD THEREFOR
(FR) AGENT DE PHOSPHATATION D’ALLIAGE DE MAGNÉSIUM, COMPOSANT MÉTALLIQUE, ET PROCÉDÉ DE TRAITEMENT DE PHOSPHATATION DE SURFACE ASSOCIÉ
(ZH) 镁合金磷化剂、金属件及其表面磷化处理方法
Abstract:
(EN) A magnesium alloy phosphating agent is used for forming a coating on the surface of a metal component, and based on 1000 parts by weight, comprises the following components in parts by weight: 0.5 parts of 2 parts of phytic acid, 5 parts of 30 parts of zinc dihydrogen phosphate, 2 parts of 5 parts of ammonium hydrogen fluoride, 1 part of 4 parts of ammonium metavanadate, 1 part of 4 parts of zinc sulfate and the balance water. A conversion film formed by the magnesium alloy phosphating agent is dense, uniform, firm and stable and has strong adhesion, and prevents the erosion of a corrosive medium to a body.
(FR) Un agent de phosphatation d'alliage de magnésium est utilisé pour former un revêtement sur la surface d'un composant métallique, et sur la base de 1000 parts en masse, comprend les composants suivants en parts en masse : 0,5 part à 2 parts d'acide phytique, 5 parts à 30 parts de dihydrogénophosphate de zinc, 2 parts à 5 parts d’hydrogénofluorure d'ammonium, 1 part à 4 parts de métavanadate d'ammonium, 1 part à 4 parts de sulfate de zinc et le reste d’eau. Une pellicule de conversion formée par l'agent de phosphatation d'alliage de magnésium est dense, uniforme, ferme et stable et présente une forte adhérence, et empêche l'érosion d'un milieu corrosif sur un corps.
(ZH) 一种镁合金磷化剂,用于在金属件表面形成皮膜,以1000重量份计,其包括如下重量份数的成分:0.5-2份植酸,5-30份磷酸二氢锌,2-5份氟化氢铵,1-4份偏钒酸铵、1-4份硫酸锌和余量水。所述镁合金磷化剂形成的转化膜致密、均匀、牢固、稳定,附着力强,阻止腐蚀介质对机体的侵蚀。
