Tungsten Carbide and Tantalum Carbide Coatings on Machining Tools

, 2009
High speed steel tools for machining were coated with WC and TaC by chemical vapor deposition (CVD), and were used in a high speed milling machine. The physical integrity of the tools coatings were analyzed by scanning electron microscopy at the end of the trials and materials surface roughness were compare in order to predict best behaviour too. These

Oxidation Behavior and Creep Resistance of Cast MC-Strengthened CoNiFeMnCr HEAs at 1100 °C

Micro
The reinforcement of cast Cantor’s-type high-entropy alloys by MC carbides and their effect on the hot oxidation behavior were investigated. Three equimolar CoNiFeMnCr alloys without or with carbon and with either hafnium or tantalum were elaborated ...

Influence of B4C and BN additiveson the structure and wear resistance of coatings producedby short-pulse laser claddingof a Ta-and SiC-based powder mixture

Frontier Materials & Technologies
The most rational approach in the production of friction units is not to manufacture the entire part from high-quality materials but to apply thin coatings (up to hundreds of micrometers) from expensive materials onto steels already widely used in ...

Preparation of refractory cermet structures for lithium compatibility testing [PDF]

High-purity nitride and carbide cermets were synthesized for compatability testing in liquid lithium. A process was developed for the preparation of high-purity hafnium nitride powder, which was subsequently blended with tungsten powder or tantalum ...

Preparation and properties of porous TaC foam ceramic filter

Journal of Materials Research and Technology
To effectively prevent the contamination of carbon particle volatiles during the preparation of high-purity SiC crystals using the physical vapor transport method (PVT) in ultra-high temperature environments (T ≥ 2000 °C), this paper innovatively employs
