On the Formation of Metal Interlayers in the Diamond–(Ti,W)C–WC–Co Composite

Autor: S. A. Davidenko

Publikováno v: Journal of Superhard Materials. 42:283-285

The stability conditions for metal interlayers at the diamond/(Ti,W)C–WC–Co matrix interface have been grounded and the critical interlayer sizes have been obtained depending on the composition and structure of the composite. The results of the r

On the Stability of Isolated Pores in Cemented Carbides (Ti,W)C—WC—Co

Autor: S. A. Davidenko

Publikováno v: Journal of Superhard Materials. 41:114-118

The investigations of the cemented carbide (Ti,W) C—WC—Co are given. It is proved that during the liquid-phase sintering in this cemented carbide the stable isolated pores did not fill with the cobalt melt. The condition is determined, during the

On the Interaction of the Cobalt Melt with Polycrystalline Tungsten Monocarbide

Autor: A. A. Matveichuk, S. A. Davidenko

Publikováno v: Journal of Superhard Materials. 40:184-188

The interaction of the cobalt melt with hot-pressed and synthesized polycrystalline WC samples was studied. It is shown that the polycrystalline WC-mesoelements are promising for the development of WC–Co mesostructural hard alloys produced by liqui
