Fe-coating-mediated carburization: A new strategy for fabricating a tungsten carbide coating on tungsten

Journal of Materials Research and Technology
A tungsten carbide (WC) ceramic coating is fabricated by a new method of Fe-coating-mediated carburization, in which the tungsten substrate is carburized using a pre-electroplated Fe coating. In this carburization process, the electroplated Fe coating is

Electrophoretic deposition prepared yttria as interface of tungsten fiber reinforced tungsten composites

Nuclear Materials and Energy, 2023
As the interface material for tungsten fiber reinforced tungsten composites (Wf/W), yttrium oxide thin films were prepared via an electrophoretic deposition (EPD) method in this study. The yttrium oxide dispersion is optimized based on its Zeta potential.

Sediment wear of turbine guide vane before and after tungsten carbide treatment

Advances in Mechanical Engineering, 2022
This paper describes three-dimensional unsteady simulations of sand–water flow within a turbine passage. Sand abrasion of a movable guide vane made from ZG06Cr13Ni4Mo is tested before and after tungsten carbide spray-coating.
