摘要：

A new approach for manufacturing-functionally graded WC-Co composites via liquid phase sintering is presented. These functionally graded WC-Co composites possess a continuous gradient in cobalt content within their microstructure. The new approach involves creating a carbon gradient in. the green state prior to liquid phase sintering. During liquid phase sintering continuous cobalt gradient develops while carbon content homogenizes. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
