Niobium carbide for machining and wear protection - Evolution of properties (2019)
Woydt, Mathias ; Huang, S. ; Cannizza, E. ; Vleugels, J. ; Mohrbacher, H.
The sales of niobium carbide (NbC) have grown in the last years, but NbC is still a hidden carbide and mainly used as grain growth inhibitor in hard metals. In the present work it was shown that the progress in the key properties, like HV30, KIC and strength, followed by machining and tribological results of the respective NbC grades.
Potentials of niobium carbide (NbC) as cutting tools and for wear protection (2018)
Woydt, Mathias ; Huang, S. ; Vleugels, J. ; Mohrbacher, H. ; Cannizza, E.
Research and development of WC grades is 90 years ahead of niobium carbide-based hard materials, which showed already as light-weight and unexplored material a very high potential for many technical applications, especially for wear protection and machining. NbC evoluted recently from lab scale to pilot scale, especially in areas where established WC-based materials are causing economic, environmental or technical concerns. Benchmark trials of NbC-based hard metals indicated already a favorable performance in machining of steel components.
Tailoring the functional profile of niobium carbide (NbC) as cutting tool materials and for wear protection (2018)
Woydt, Mathias ; Huang, S. ; Vleugels, J. ; Mohrbacher, H. ; Cannizza, E.
In the present work it was shown that the properties of NbCx, like micro-hardness, hot-hardness, sliding wear resistance, elastic modulus and toughness can be tailored by the C/Nb ratio, the addition of secondary carbides and the type of binder.
Influence of sintering temperature and carbide additions on the microstructure and mechanical properties of NbC-Ni based cermets (2018)
Vleugels, J. ; Cannizza, E. ; Woydt, Mathias ; Mohrbacher, H.
This study reports on the effect of the sintering temperature and VC, Mo2C and TiC as well as the combination of Mo+VC on the densification, NbC grain growth, microstructure evolution as well as mechanical properties of novel NbC-Ni based cermets.
Niobium carbide based cermets with secondary carbide and carbonitride addition (2018)
Huang, S. ; Vleugels, J. ; Cannizza, E. ; Woydt, Mathias ; Liu, Z. ; Mohrbacher, H.
In this study, the influence of Ni binder content and carbide/carbonitride additions on the microstructure and mechanical properties of NbC-Ni matrix cermets were investigated.
