Patent number: 6564854Abstract: In a semi-solid alloy including a large amount of a liquid phase portion, that is, semi-solid alloy with less than 50% of solid phase rate, there is a tendency for a solid phase portion to concentrate into the central portion in the direction of thickness, that is the internal portion. In order to enhance corrosion resistance at a portion where high corrosion resistance is particularly required in parts molded by semi-solid injection, the above tendency is utilized. By utilizing the tendency, a layer consisting of a liquid phase portion is partially formed at the semi-solid state on a surface portion where high corrosion resistance is required.Type: GrantFiled: December 29, 1999Date of Patent: May 20, 2003Assignee: Mazda Motor CorporationInventors: Nobuo Sakate, Shoji Hirabara, Kazuo Sakamoto, Yukio Yamamoto

Patent number: 6552292Abstract: When a seat (3) (FIG. 6A) on which a wax layer (7) is formed via a melting reaction layer (5) is brought into contact with a head (2) and heated and pressed in this state, a melting reaction layer (6) forms below the wax layer (FIG. 6B). When electric current application and pressing are continued from this state, a wax which has not reacted in the wax layer (7) in the formation of the melting reaction layer (6) is discharged from between the melting reaction layers (5) and (6). When electrical current application and pressing are further continued from this state, the two melting reaction layers (5) and (6) diffuse each other. The result is that a ternary alloy bonding layer (10) containing Fe, Al, and Zn, which constitute the melting reaction layers (5) and (6) is formed between the seat (3) and the head (2) (FIG. 6D).Type: GrantFiled: February 3, 2000Date of Patent: April 22, 2003Assignee: Mazda Motor CorporationInventors: Seiji Nomura, Satoshi Nanba, Yukihiro Sugimoto, Yukio Yamamoto
