Tungsten carbide is harder but more brittle than steel, so it can crack or shatter from a strong enough impact. Tungsten carbide tools are more expensive than steel but are usually more valuable in the long run because they last much longer. Tungsten carbide maintains a sharp cutting edge longer than steel, produces a better finish, and …
According to a 2021 report from the International Journal of Refractory Metals and Hard Materials, the estimate for the current overall global recycling rate of tungsten carbide …
In extremely alkaline media (pH 11 and higher), the carbide phase or tungsten carbide (WC) is evenly abraded by corrosion. This leads to a slightly increased rate of degradation, which (subsequently) can be noticed on the component as …
Tungsten carbide coatings are obtained by atmospheric pressure CVD in this study, and the coatings' phase changed from W 3 C + W to W 2 C + W with the increase of P DME due to more C being generated by the reaction of WF 6 and DME. The growth rate and grain size of the coatings decreased when the P DME increased because C …
It is usual practice to optimize the various processing parameters in order to achieve well-organized and lucrative process conditions. For the creation of tungsten carbide/silicon nitride/AA2219 composites, sintering temperature, sintering pressure, dwelling time, and heating rate all must be optimized. Design of experiments and …

Gulbransen and Wysong3 investigated the oxidation of tungsten in oxygen in the tempera- ture range 25-550 and found that the oxida- tion rate was strongly dependent on the temperature with a marked increase in oxida- tion rate at temperatures above 300. The oxidation behaviour of tungsten is affec- ted by humidity.
