摘要：

Hot isostatic pressing (HIP) is used to densify high performance cemented tungsten carbide parts to improve mechanical properties. Recent discoveries indicate that cemented tungsten carbides can be HIPed at lower pressures than have traditionally been thought necessary to reduce porosity. New equipment able to dewax/sinter/HIP in the same furnace is available. Low pressure test results to date promise cost improvement with equivalent or improved quality. This paper compares equipment technology and processing cost of two methods: conventional HIP rated to 100 MPa, and low pressure dewax/sinter/HIP rated to 10 MPa.
