Title:
METHOD FOR PRODUCING METAL-CERAMICS COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JP2016199459
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a metal-ceramics composite material, in which even when the metal-ceramics composite material has a comparatively thick product shape, a void can be restrained from being formed on the inside of a product due to solidification shrinkage.SOLUTION: The method for producing the metal-ceramics composite material, in which a molten metal is infiltrated into a preform comprising a ceramic particle to obtain the metal-ceramics composite material, comprises the steps of: preparing the preform, which is composed of a product part preform for constituting a product part comprising the ceramic particle and a molten metal replenishment part composed of a porous body comprising ceramics, so that the average pore diameter of the molten metal replenishment part is made equal to or larger than that of the product part preform; infiltrating the molten metal into the preform to produce an infiltrated body; and solidifying the molten metal infiltrated into the product part infiltrated body while holding a product part infiltrated body consisting of the product part preform and a molten metal replenishment part infiltrated body consisting of the molten metal replenishment part as one body.SELECTED DRAWING: Figure 1
