摘要

This study investigates the microstructural characteristics and adhesion properties of AlFeCr coatings deposited on W320 hot work alloy steel via magnetron sputtering. The aim was to enhance adhesion properties by optimizing substrate temperature and interlayer design. The results reveal that higher substrate temperatures during deposition improve adhesion, while the introduction of gradient interlayers enhances coating compactness and continuity, reducing delamination and promoting cohesive cracking under stress. These findings highlight the critical role of interlayer engineering in optimizing the performance and durability of protective coatings.
