The interconnected porosity of the Cr3C2–NiCr coatings obtained by high-velocity oxy fuel spraying is detrimental in corrosion and wear resistance applications. Laser treatments allow sealing of their surfaces through melting and resolidification of a thin superficial layer. A Nd:YAG laser beam was used to irradiate Cr3C2–NiCr coatings either in the continuous wave mode or at different repetiti...

In this study, a Cr3C2-NiCr cermet cladding layer was prepared on the surface of Q235 steel via high-speed laser method. The effects power, scanning speed, and overlap rate microstructure, quality, interfacial elements diffusion Cr3C2-NiCr/Q235 were studied. results show that there an obvious transition at interface steel, indicating had adequate metallurgical bond with matrix. Fe, Cr, Ni diffu...

A top DLC film was deposited on the surface of Cr3C2-NiCr coated 38CrMoAl steel substrate, and effect cermet interlayer thickness mechanical tribological properties duplex coating investigated by experimental analysis finite element modeling (FEM). Results shown that, compared with single film, load-bearing capacity performance DLC/Cr3C2-NiCr were significantly improved, especially its anti-wea...

Graphene nano platelets (GNP) have several attractive properties, including excellent lubricity that can be used to develop wear-resistant coatings. Thermally sprayed chromium carbide–nickel (Cr3C2–NiCr) coatings are widely employed impart wear resistance engineering components. This work attempts improve the of high velocity air fuel (HVAF) Cr3C2–NiCr by incorporating GNP using a hybrid approa...
