Title:
MANUFACTURE OF CYLINDER BLOCK
Document Type and Number:
Japanese Patent JP3788667
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the tensile strength and proof stress by impregnating a ceramic reinforcement material, in a molten bath of an aluminium alloy in a reducing atmosphere, and then extruding and molding the same.
SOLUTION: An aluminium alloy 7 is placed on a preform 6 obtained by molding a ceramic reinforcement material, in a crucible 5, a magnesium generating source 9 is placed in the other crucible 8, an argon gas 2c is introduced into an atmospheric furnace 1 for the displacement, the magnesium steam heated by a heating means 4, is permeated and dispersed inside of the preform 6, and then a nitrogen gas 2a is introduced, whereby the magnesium nitride is brought into contact with the fiber of the preform 6 or the alumina on the surface, and the reducing reaction is advanced, to prepare the aluminium group composite material, which is combined by the chemical contact. Then the surface thereof is removed, and the composite material is cylindrically molded by an extrusion molding machine to form a pipe-shaped member. A cylinder liner obtained by cutting the pipe member by a specific size, is set in a mold, and the Al alloy is poured to form a cylinder block integrated with an Al alloy block.
