Coatings in a Zr-Mo-Si-B-N system were deposited by the magnetron sputtering of ZrB-MoSi targets in argon and nitrogen. The structure of the coatings was investigated using scanning electron microscopy, X-ray diffraction, energy-dispersive spectroscopy, and glow-discharge optical emission spectroscopy. Mechanical and tribological properties were measured using nanoindentation and pin-on-disc testing. Oxidation resistance and oxidation kinetics were estimated via annealing in air at 1000-1500 °C and precision weight measurements. We found that the coatings deposited in Ar demonstrate a superior combination of properties, including hardness of 36 GPa, elastic recovery of 84%, a friction coefficient of 0.6, and oxidation resistance at temperatures up to 1200 °C. High oxidation resistance is realized due to the formation of the protective (SiO + ZrO)/SiO oxide layer, which inhibits the diffusion of oxygen into the coating.
通过在氩气和氮气中对ZrB-MoSi靶材进行磁控溅射,在Zr-Mo-Si-B-N体系中沉积涂层。使用扫描电子显微镜、X射线衍射、能量色散光谱和辉光放电光发射光谱对涂层结构进行了研究。使用纳米压痕和销盘测试测量了力学和摩擦学性能。通过在1000-1500°C的空气中退火和精确重量测量来评估抗氧化性和氧化动力学。我们发现,在氩气中沉积的涂层表现出优异的综合性能,包括36 GPa的硬度、84%的弹性回复率、0.6的摩擦系数以及在高达1200°C的温度下的抗氧化性。由于形成了保护性的(SiO + ZrO)/SiO氧化层,抑制了氧气向涂层中的扩散,从而实现了高抗氧化性。
