Sintering of binderless WC-Mo2C hard materials by rapid sintering process

High-frequency induction heated sintering (HFIHS) is a new rapid sintering method which was developed recently for the fabrication of ceramics and composites. Results on the sintering of binderless WC-x wt%Mo2C (x = 0-6) hard materials using ultra fine powders of WC and Mo2C are reported. A complete...

Description
Summary:High-frequency induction heated sintering (HFIHS) is a new rapid sintering method which was developed recently for the fabrication of ceramics and composites. Results on the sintering of binderless WC-x wt%Mo2C (x = 0-6) hard materials using ultra fine powders of WC and Mo2C are reported. A complete densification of the materials was achieved within 1 min. The relative densities of the composites were about 99% for an applied pressure of 60 MPa and an induced current for 90% output of total capacity. The Vickers hardness decreased and the fracture toughness increased with increasing Mo2C content. 21 refs.
