Effect of laser scanning speed on microstructure and properties of Fe based amorphous/ nanocrystalline cladding coatings

Effect of phase transformation on mechanical properties of Al16.80Co20.74Cr20.49Fe21.28Ni20.70 high entropy alloy coatings processed by laser cladding

“…But the average nano-hardness value of V17 was slightly smaller than that of V13, which was 6.4GPa. The results show that as the laser scanning speed increases, the nano-hardness of the coatings shows an overall increasing trend, which was also found in previous studies [33][34].The elastic modulus contour map of V7, V13 and V17 were shown in Fig. 10 (a2), (b2) and (c2), respectively.…”

Synergistic Effect of Composite V2O5/Ca0.17V2O5 Film Electrodes as High-Performance Cathodes of SIBs

“…The I corr of V 2 O 5 is 6.720 μA cm –2 , which is lower than that of V 2 O 5 /Ca 0.17 V 2 O 5 (9.269 μA cm –2 ). That indicates that the V 2 O 5 possesses a better corrosion resistance, and the V 2 O 5 /Ca 0.17 V 2 O 5 has a higher charge transfer rate. , Meanwhile, the corrosion potential ( E corr ) can represent thermodynamic tendency to oxidation or passivation. , The E corr of V 2 O 5 /Ca 0.17 V 2 O 5 is −0.022 V, which is higher than that of V 2 O 5 (−0.047 V). The higher E corr means the V 2 O 5 /Ca 0.17 V 2 O 5 film electrode has a lower thermodynamic tendency to oxidation or passivation, which can be ascribed to the different chemical composition and microstructure. , To understand the electrode reaction kinetics of films, EIS measurements are characterized in Figure b.…”

Fe-based metallic glass coatings by thermal spraying: a focused review on corrosion properties and related degradation mechanisms

“…The various synthesis routes used to produce the metallic glass coatings are pulsed laser deposition (PLD), magnetron sputtering, laser cladding and thermal spraying [85,86,108,109,[110][111][112][113][114]. Both PLD and sputtering techniques suffer from a major drawback of low deposition rate, while during laser cladding process stress development in the coatings would be problematic; therefore, synthesizing thicker coatings via these processes is very difficult.…”
