With the improvement of human ability to produce materials,alloy coatings have evolved from containing simple composition to containing complex compositions.And containing multiple major components causes the high-entropy alloy coatings to present high thermal stability and wear resistance,as well as excellent fatigue resistance,high temperature tensile property,corrosion resistance and magnetic properties,and these excellent properties make them exceed the application range of conventional alloy coatings and bring them many potential application prospects.The study of the relationship between microstructure and properties of high-entropy alloy coatings is important for the further development of high-entropy alloy coating materials with better performance.In this paper,the characteristics and application area of conventional high-entropy alloy coatings,refractory high-entropy alloy coatings,composite high-entropy alloy coatings and lightweight high-entropy alloy coatings were reviewed,and the effects of the types of high-entropy alloy coatings on their mechanical properties,frictional properties and corrosion resistance were introduced,and finally an outlook on the development of high-entropy alloy coatings was provided. |
