Abstract
本发明公开了一种微纳多级异质结构的共晶高熵合金耐磨蚀涂层及其制法与应用。所述共晶高熵合金耐磨蚀涂层中化学元素组成的通式为AlaCobCrcFedNieTifNbg，所述共晶高熵合金耐磨蚀涂层包括FCC相及BCC相域，所述BCC相域分布于作为基体的FCC相内，所述BCC相域内部形成纳米尺度成分调制区，所述纳米尺度成分调制区由无序BCC相与有序B2相构成；所述共晶高熵合金耐磨蚀涂层具有微米尺度的FCC / BCC双相异质结构和纳米尺度的BCC / B2异质结构。本发明中涂层的微纳多级异质结构有利于提高涂层在海水环境中的耐蚀性和抗磨损‑腐蚀耦合损伤能力，适用于海洋装备关键部件的表面防护。
