摘要：
CoCrNiMoCB high-entropy alloy composite coatings were made by laser cladding, then the effects of Co concentration on corrosion resistance were studied. The addition of Co can reduce the composition difference between the FCC matrix and strengthening phase, thus reducing the potential difference and the driving force for galvanic corrosion. Through first-principle calculation, it was concluded that the addition of Co can increase the electronic work function and reduce the interface bonding energy, thus, enhancing the corrosion resistance and improving the interface bonding strength.
