    • A process for the production of a highly corrosion-resistant composite which is composed of both a magnesium part or a magnesium alloy part and a resin composition and which is improved in corrosion resistance, comprising the step of forming a magnesium alloy part (1) out of an ingot or an intermediate material, the step of immersing the magnesium alloy part in an aqueous acid solution to conduct chemical etching, the step of immersing the chemically etched part in an aqueous solution of potassium permanganate to form a thin layer containing manganese oxide as the main component on the surface of the part, the step of inserting the resultingpart into an injection mold and injecting one member selected from among resin compositions comprising polyphenylene sulfide as the main component, resin compositions comprising polybutylene terephthalate resin as the main component, and resin compositions comprising aromatic polyamide resins as the main component into the resulting mold to unite the part (1) and the resin composition (4) and thus form a composite (7), and the step of immersing the composite (7) again in a chemical conversion treatment solution for magnesium alloys to conduct chemical conversion treatment. ® KIPO & WIPO 2009
    • 一种由镁部分或镁合金部分和树脂组合物组成并且耐腐蚀性提高的高耐腐蚀复合材料的制造方法,包括以下步骤:将镁合金部件(1) 的铸锭或中间材料的步骤,将镁合金部分浸渍在酸性水溶液中以进行化学蚀刻的步骤,将化学蚀刻部分浸渍在高锰酸钾水溶液中以形成含有氧化锰的薄层的步骤 部件表面的主要部件,将所得部件插入注射模具中并注入从以聚苯硫醚为主要成分的树脂组合物中选出的一种物质,以聚对苯二甲酸丁二醇酯树脂为主要成分的树脂组合物和树脂 包含芳族聚酰胺树脂作为主要成分的组合物组合到所得模具中以组合 e部分(1)和树脂组合物(4),从而形成复合材料(7),以及将复合材料(7)再次浸入镁合金化学转化处理溶液进行化学转化处理的步骤。 ®KIPO&WIPO 2009
