Abstract

A sleeve mold for a method of high-throughput hot isostatic pressing micro-synthesis for combinatorial materials includes a honeycomb-array-sleeve and an upper cover, wherein a plurality of single cells are tightly arranged inside the honeycomb-array-sleeve, an exhaust tube is arranged on the upper cover, after the single cells are filled with powder materials, the upper cover is sealed welding on the honeycomb-array-sleeve, and the honeycomb-array-sleeve and the upper cover are both integrally produced by additive manufacturing. According to the method and the sleeve mold, the powder metallurgy hot isostatic pressing process is utilized to prepare small-size bulk combinatorial materials with multiple discrete components rapidly at one time.
