Patent number: 9260133Abstract: Disclosed is a friction-stir welded structure in which corrosion resistance of a peeling region is ensured when a film coating is peeled away from a steel sheet. In a sub-frame, an aluminum alloy member is laid over a steel member that has been electropainted, and the overlaid part where the member is laid over is friction-stir welded at inner and outer welds. The aluminum alloy member has an aluminum layered part which together with the steel member constitutes the overlaid part due to being laid over the steel member, and aluminum extending parts provided to the aluminum layered part. The aluminum extending parts have aluminum extending parts that are orthogonal to the extending direction of the inner and outer welds and that protrude outward from the steel member.Type: GrantFiled: May 30, 2013Date of Patent: February 16, 2016Assignee: Honda Motor Co., Ltd.Inventors: Tsunehisa Hata, Toshikazu Hirobe

Patent number: 5537969Abstract: A cylinder block is produced by subjecting an outer surface of a cylinder sleeve section Sc of cast iron to a shot blast treatment, forming a first intermediate layer 31 of aluminum-based material containing Si, Cu and the like on the cylinder section Sc, and inserting the cylinder sleeve section Sc in a cast-in manner within a cylinder barrel 1.sub.U of aluminum alloy. The electrical-potential difference between the cylinder sleeve section Sc and the cylinder barrel 1.sub.U and the first intermediate layer 31 is decreased by the first intermediate layer 31 to enhance the durability against an electrolytic corrosion and to enhance the deposition by a mutual diffusing action therebetween. In a modification, a second intermediate layer 32 of a Ni-Al based material is formed under the first intermediate layer 31 at a portion of the cylinder sleeve section Sc inserted in a cast-in manner within the cylinder barrel 1.sub.U, whereby the adhesion can be further enhanced.Type: GrantFiled: April 18, 1995Date of Patent: July 23, 1996Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tsunehisa Hata, Hideo Shimizu, Kenji Matsumoto
