Problems solved by technology

[0004] At present, methods such as electrochemical deposition, magnetron sputtering deposition, and laser cladding are used to prepare high-entropy alloy coatings, but the thickness of the coatings prepared by some of these methods can only reach the micron scale, and the bonding strength is not enough, so it is difficult to exert high-entropy alloys. The advantages of entropy alloy performance, some methods have expensive equipment, high energy consumption, and complicated operation
