Phase constitution, microstructure and properties of pulsed laser-clad ternary CrNiTi medium-entropy alloy coating on pure titanium

Surface hardening of CrCoFeNi high-entropy alloys via Al laser alloying

“…Hunt [30] and Gäumann et al [31] also suggested that high density of nucleation sites can be conducive to the formation of equiaxed grains despite high G values. Chai et al showed that rapid non-equilibrium solidification during laser processing is conducive to grain refinement [32].…”

A review of advances in tribology in 2020–2021

“…Addition of Si element to AlCoCrFeNi HEA [567], Ti element to AlCoCrFeNi HEA [568] or increase in the ratio of B/Si in the laser cladded Fe 25 Co 25 Ni 25 (B x Si 1-x ) 25 [569], reduced the friction coefficient and wear rate. Laser cladding HEA coatings of ternary CrNiTi on pure titanium [570], and nano-lamellar Ni 1.5 CrCoFe 0.5 Mo 0.1 Nb x on stainless steel [571] were also reported. Other HEA coatings of CrNbSiTiZr by radio-frequency magnetron sputtering [572], of Fe 17 Cr 2 Ni 0.2 C by thermal spraying [573], of AlxCoCrFeNiSi by atmospheric plasma spraying and laser re-melting were fabricated and | https://mc03.manuscriptcentral.com/friction characterized.…”

Preparation of medium-entropy alloy coating using GMAW cladding with MoFe3TiNiCu cable-type welding wire

“…In recent years, more and more scholars have devoted themselves to the research of medium-entropy alloys (MEAs), which makes MEA coatings become the hotspot and frontier of material science research. Various MEA coatings with different compositions have been prepared by different processes, such as electrospark deposition [15], high-velocity oxygen-fuel (HVOF) spraying [16], resistance seam processing [17], laser cladding [18,19], electron beam cladding [20], RF magnetron co-sputtering [21], plasma cladding [22] and extreme-high-speed laser material deposition [23]. It is still a work of great academic value and application value to explore new technologies to obtain MEA coatings.…”
