摘要： An iron based sintered body suitable for being enveloped in a light metal alloy such as an aluminum alloy by casting, and a method for producing the same. A mixed powder is prepared by mixing an iron based powder, a copper powder and a graphite powder blended so that the Cu content and the C content are 5 to 40% by mass and 0.5 to 2.5% by mass, respectively, in the mixed powder. A lubricant powder and a fine particle powder for improving machinability may be further added in the mixed powder. Then, the mixed powder is filled into a mold formed to a green compact, and is sintered into a sintered body so that the sintered body has a desired average thermal expansion coefficient. The surface of the sintered body may be adjusted to have a surface roughness Rz of 10 to 100 μm optionally by applying a shot blast treatment or by a shot blast treatment and an additional steam treatment. This process permits the sintered body to be enhanced in adhesive property and bonding strength while being improved in enveloping casting property when the sintered body is enveloped in the light metal alloy by casting. A martesitic stainless steel powder or ferritic stainless steel powder may be used instead of the pure iron powder, or Cr, Mo and W powders may be further blended.

摘要： When a cylinder block is cast, a bearing housing is constituted by a preform integrally cast with the cylinder block. In order to raise the strength of the bearing housing, a metal matrix composite is formed around the preform. The preform is constituted by a high volume factor member having a relatively high volume factor and two low volume factor members having a relatively low volume factor connected with top and under surfaces of the high volume factor member respectively. The high volume factor member is made of solid metal and the low volume factor member is made of sintered metal filaments. Base material of the cylinder block infiltrates into the low volume factor member to form a metal matrix composite in the preform.

摘要： The cylinder liner is capable of being tightly adhered to an aluminium block. The cylinder liner is made of cast iron and formed into a cylindrical shape. In the cylinder liner, slender section is provided in a middle portion, and outer diameter of the cylinder liner is gradually made greater toward both end sections from the slender section. A plurality of projected lines are formed on an outer circumferential face of the cylinder liner with regular separations and extended in the axial direction thereof. With this structure, the cylinder liner can securely stay in a cylinder block even if an external force in the axial direction works to the cylinder liner. In the cylinder block of the present invention, a plurality of the cylinder liners are enclosed with casted aluminium.
