Tribological properties of HVOF-sprayed WC-Co coatings deposited from Ni-plated powders at elevated temperature
TL;DR: In this article, Ni/mc-WC and Ni/nc-WC coatings were investigated by using sintered alumina (Al2O3) as the mating material at 700°C.

Microstructure-property relations in WC-Co coatings sprayed from combinatorial Ni-plated and nanostructured powders
TL;DR: In this paper, the effects of Ni-plating and nanostructuring of WC-Co powders on the microstructure-property relations and WC decarburization of WCCo composite coatings were addressed.

Competitive grain boundary segregation of phosphorus and carbon governs delamination crack in a ferritic steel
TL;DR: In this paper, the influence of trace amounts of phosphorus on the macro-scale delamination in a ferritic steel has been revealed, and two different steels with trace amount of phosphorus were examined to reveal the cause.

High temperature oxidation behavior of micro/nanostructured WC-Co coatings deposited from Ni-coated powders using high velocity oxygen fuel spraying
TL;DR: In this article, high temperature oxidation of WC-based cermet coatings deposited from electroless Ni-coated micro and nanostructured WC-Co powders (Ni/mc-WC and Ni/nc-WC) was studied.
