对射频磁控溅射沉积的ZrO2-12wt%Y2O3薄膜进行了电子束处理和热退火处理。通过XRD,XPS,SEM等的微观分析,研究了薄膜的相结构组成,薄膜主要组成元素的氧化态以及薄膜的形貌特征。并对以提高薄膜增韧性为目的而进行的后处理的方式选择作了讨论。 相似文献

Tungsten films were deposited on stainless steel Charpy specimens by magnetron sputtering followed by electron beam heat treatment. Charpy impact tests and scanning electron microscopy were used to investigate the ductile-brittle transition behavior of the specimens. With decreasing test temperature the fracture mode was transformed from ductile to brittle for both kinds of specimens with and without W films. The data of the crack initiation energy, crack propagation energy, impact absorbing energy, fracture time and deflection as well as the fracture morphologies at test temperature of-70 ℃ show that W films can improve the impact toughness of stainless steel. 相似文献

在不同温度衬底上射频磁控溅射沉积ZrO2-12wt%Y2O3薄膜进行了不同方式的退火后处理。其一为1000℃大气气氛下的热退火处理,其二为高真空渗氧条件下的电子束退火处理。退火前后的相结构和显微形貌的研究表明,退火前的沉积膜相组成与沉积过程中衬底温度有关,退火后的沉积膜相组成与退火方式有关,其形貌特征经不同形式退火显示出明显的差别。 相似文献
