Abstract It has been suggested that Cr-coated zircaloy is an excellent material for accident-tolerant fuel (ATF) cladding. found Cr coating shows multi-cracking behavior under external load due to its embrittlement. Different fabrication parameters will lead different crack resistances of the coatings, but brittle cracking characteristic common. The estimation strength and structural integrity ...

An Fe6AlCoCrNi medium-entropy (MEA) coating was coated on a steel substrate by laser cladding. The micro-structure, crystal structure, phases, and wear properties of the were investigated. mainly composed dendritic face-center cubic (FCC) phase, which showed preferred orientation <2 0 0>, normal to surface, body-center (BCC) phase. MEA exhibited satisfactory rigidity with superior resista...

NiAl composite coating strengthened by ZrC and ZrB2 phases is synthesized the plasma cladding process. The influence of speed on microstructrue properties coatings studied. main are NiAl, γ-(Fe,Ni), phases. in shape points small blocks, shows long strips needle bar. slower speed, larger size reinforcing With increase wear resistance improves. Coating with 10mm/s has excellent wear-resistance pr...

Y2O3-reinforced Al-Si alloy coatings were prepared on the surface of a Mg by laser cladding technique. The microstructure, hardness, and wear resistance analyzed using an X-ray diffractometer, scanning electron microscope, energy spectrometer, Vickers hardness tester, friction tester. effect different additions Y2O3 microstructure properties was investigated. results indicate that addition lead...
