ABSTRACT:
The present invention provides for a bolt structure for use with a magnesium alloy member that can insulate between magnesium alloy members and steel or other bolts without lowering the bolt shaft power, and prevent occurrence of electrolytic corrosion with an electrolyte such as water. A cationic electrodeposition coating is also provided for the bolts structure, said coating having a film thickness of 15 μm or more is provided at least on the surface of the magnesium alloy member contacting with a bolt head, a powder coating having a film thickness of 40 to 150 μm is provided on the surface of the cationic electrodeposition coating, zinc-nickel plating and then cosmer treatment are carried out on the bolt, and an alumite-treated aluminum washer is interposed between the bolt head and the magnesium alloy member.
