Production of Porous Sintered Metal by Slurry Casting 2'nt Report

Giving One Dimensional Surface Porosity by Combining Electrostatic Fiber Planting

Abstract

Porous metal which has one directional porosity perpendicular to the surface, can be produced by the combination of slurry casting and fiber planting. First, fine short metal fiber is planted on the surface by electrostatic fiber planting, i.e.flocking and secondly metal powder slurry including ethyl silicate binder is casted on the fiber planted surface. At the subsequent sintering, metal powder is melted and infiltrated into metal powder matrix, which yieds long and one directional pores. Here, Cu fiber and Fe powder are used and electric coinductive vacuum chuck for grinding was experimentally producted.
