Abstract
A structure and a method of preventing electrolytic corrosion for a magnesium alloy member (20), the structure wherein a first coated layer (11) formed by electro deposition and a second coated layer (12) formed by distributing PTFE particles on the first coated layer (11) are covered on the surface of a tightening member (1) at least on a surface coming into contact with the magnesium alloy member (20), whereby, the electrolytic corrosion of the magnesium alloy member can be prevented at a low cost by insulating a tightening member such as a steel bolt and a washer from the magnesium alloy member, and an adhesiveness therebetween can be sufficiently assured.
