It has been reported that grain growth is especially rapid in the early stages of sintering. In [], densification and grain sizes in a nanosize WC – Co powder were studied depending on the duration of liquid-phase sintering (5, 15, 30, 60, 90, 180 and 360 min) and on its temperature (1630, 1670, 1710, 1750 K).The grain size in the samples increased …

To explore the Co/Cr ratio impact on the high-velocity oxygen fuel (HVOF)-sprayed WC-Co-Cr coatings microstructure and performances, three kinds of WC-Co-Cr coatings, namely WC-4Co-10Cr, WC-7Co-7Cr, and WC-10Co-4Cr, were prepared by using a high-velocity oxygen fuel (HVOF) spraying process. The three coatings' phase …

Referring to the literature, a radius of 40 Å and a speed of 40 m/s were used for the indenter in both loading and unloading simulations.The simulated systems of WC and Co both have dimensions of 144.73 × 150.40 × 84.06 Å 3 (~ 170,000 atoms). For the WC-Co composite, the dimensions are 145.00 × 154.100 × 170.00 Å 3 (~ 350,000 atoms).

The quasi-plastic deformation behavior of cemented tungsten carbide (WC-Co) materials was studied using Hertzian indentation techniques. The indentation stress-strain curves of three WC-10 wt pct Co alloys with different hardness values demonstrate that WC-Co alloys exhibit "quasi-plasticity" behavior under indentation load and the …

Dilatometer densification measurements were performed on WC-Co composites containing 2, 5 and 10 wt% Co.The runs were carried out under a flow of 10% H 2-Ar up to 800 °C followed by vacuum up to 1400 °C. Analysis of diffusional densification kinetics suggest an initial solid state densification from 800 to about 1190 °C attributed …

WC-Co hardmetals are widely used in wear-resistant parts, cutting tools, molds, and mining parts, owing to the combination of high hardness and high toughness. WC-Co hardmetal parts are usually produced by casting and powder metallurgy, which cannot manufacture parts with complex geometries and often require post-processing such as machining. Additive manufacturing (AM) technologies are able ...

In contrast to the much larger grain size of the binder phase in traditional WC–Co cemented carbide, we have achieved a significantly reduced grain size of the γ′-Ni 3 Al strengthened composite binder phase in WC–Co–Ni–Al cemented carbide. Based on thermodynamic calculations, decisive experiments and microstructure characterizations, …

Here, a novel 3D diatomite plate@polydopamine@WC (DPW) was synthesized by a two-step impregnation method to construct a DPW/Fenton system for the degradation of NOR at near-neutral pH. The co-catalytic properties of DPW were compared with powdered MoS 2, WS 2, and WC through a comparative research method. The morphology, pore size, …
