The scratching test was carried out with a single diamond tool to study the removal mechanism of litao3 wafer by load. the ae signals were measured, and the scratched surfaces of litao3 wafers in different conditions were observed by metallography microscope
通過單顆粒金剛石壓入鉭酸鋰晶片光滑表面的劃痕實驗,研究鉭酸鋰晶片的機械力學性能和斷裂破壞情況,尋找合理的拋光壓力。It is found that the great cracks on the coarse surface are initiated easily than on the smooth surface by the sem observation and the crack size obtained at the dynamic indentation experiment is bigger than at the static indentation experiment under the same load. it is showed the single crystal silicon is easier to initiate the crack and fracture under dynamic load, the single crystal silicon ’ s
然後通過sem觀察單晶硅試件表面壓痕形貌,發現粗糙表面比光滑表面容易生成大裂紋,在相同載荷作用下單晶硅材料在動態壓痕試驗得到的裂紋要大於在靜態壓痕試驗得到的裂紋,表明在動態加載條件下單晶硅材料更容易生成裂紋和破碎。
