摘要 CrAlYN coatings with different Y contents(0,5 and 12 at.%)were deposited by cathodic arc evaporation to investigate the influence of Y-addition on the structure,mechanical and thermal properties of CrAlN coatings by using X-ray diffraction,scanning electron microscopy,differential scanning calorimetry,thermal gravimetric analysis and nanoindentation.The structural transformation of single phase cubic Cr_(0.42)Al_(0.58)N and Cr_(0.39)Al_(0.56)Y_(0.05)N coatings to cubic−wurtzite mixed Cr_(0.32)Al_(0.56)Y_(0.12)N coating leads to a drop in hardness from(30.2±0.7)GPa of Cr_(0.42)Al_(0.58)N and(32.0±1.0)GPa of Cr_(0.39)Al_(0.56)Y_(0.05)N to(25.2±0.7)GPa of Cr_(0.32)Al_(0.56)Y_(0.12)N.The incorporation of 5 at.%Y retards the thermal decomposition of CrAlN,verified by the postponed precipitation of w-AlN and N-loss upon annealing.Correspondingly,Cr_(0.39)Al_(0.56)Y_(0.05)N coating consistently exhibits the highest hardness value during thermal annealing.Nevertheless,alloying with Y exerts an adverse effect on the oxidation resistance of CrAlN. 采用阴极弧蒸发法制备不同Y含量(0、5%和12%,摩尔分数)的CrAlYN涂层,使用X射线衍射、扫描电子显微镜、差示扫描量热仪、热重分析仪和纳米压痕技术研究Y掺杂对CrAlN涂层结构、力学性能以及热性能的影响。Cr_(0.42)Al_(0.58)N和Cr_(0.39)Al_(0.56)Y_(0.05)N涂层为单相立方结构,而Cr_(0.32)Al_(0.56)Y_(0.12)涂层为立方−六方混合结构,由于结构的转变,涂层硬度值由Cr_(0.42)Al_(0.58)N的(30.2±0.7)GPa和Cr_(0.39)Al_(0.56)Y_(0.05)N的(32.0±1.0)GPa下降到Cr_(0.32)Al_(0.56)Y_(0.12)N的(25.2±0.7)GPa。热退火过程中六方AlN相的析出延迟以及N损的延迟证明添加5%Y能够延缓CrAlN涂层的热分解,相应地,Cr_(0.39)Al_(0.56)Y_(0.05)N涂层在退火过程中始终表现出最高的硬度值。然而,Y的掺杂对CrAlN涂层的抗氧化性产生不利的影响。
