Functional-gradient WC-TiC cemented carbides with alternative binders (Ni and Fe)

In this work we investigate the development of functionally graded cemented carbides, featuring macro gradients on the millimeter scale, where Fe, or Ni is the binder phase.

Decarburization mechanisms of WC-Co during thermal spraying: Insights from controlled carbon loss and microstructure characterization

, 2013
Decarburization behavior of WC–Co particles in terms of transformation of WC to W2C and W, and formation of η and γ phases and microstructure evolution during plasma spraying have been systematically investigated in this study.

Identification and accurate characterisation of the metastable CoFCC phase in WC–Co cemented carbides

Composed of hard tungsten carbide (WC) particles and a soft cobalt (Co) matrix, WC–Co cemented carbides exhibit significant differences in the material removal rates of these phases during metallographic preparation.

A Study on the Plane Strain Fracture Toughness of WC-Co and TiC-Ni Composites

, 1985
본연구에서는 WC-Co 및 TiC-Ni계 복합재료의 탄화물 입도, 결합상의 평균자유 행로, 합금원소 및 탄화물의 체적분율의 변화에 따른 평면변형 파괴인성을 방전가공에 의해 노?「? 부여한 SENB시편을 사용하여 측정하였다. 또한 복합재료인 WC-Co 및 TiC-Ni합금의 기계적 성질을 조사하기 위하여 경도, 항절력, 충격강도 및 Palmqvist 균열저항도 측정하였으며 얻어진 결론은 다음과 같다.

HPC-milling of WC-Co cemented carbides with PCD

, 2018
In order to machine wear parts of small lot size made out of WC-Co cemented carbides, milling can be an economically promising alternative to grinding or electrical discharge machining (EDM) for finishing after sintering.

Novel titanium carbide based hard metal alternative for traditional WC-Co

, 2015
Cemented carbides are primarily used in metal cutting tools, metal forming tools (e.g. dies), construction and mining equipment where unique combination of mechanical, physical, and chemical properties are needed.
