coating inserts%α-Al2 O3%grain size%cutting property
采用CVD法在硬质合金基体上沉积了4种不同晶粒大小的α-Al2 O3涂层。通过SEM分析了氧化铝涂层晶粒大小及特点，并对4种氧化铝涂层刀片进行喷砂后处理及切削试验。发现氧化铝晶粒越细，晶粒越均匀，涂层刀片切削性能越优异。
採用CVD法在硬質閤金基體上沉積瞭4種不同晶粒大小的α-Al2 O3塗層。通過SEM分析瞭氧化鋁塗層晶粒大小及特點，併對4種氧化鋁塗層刀片進行噴砂後處理及切削試驗。髮現氧化鋁晶粒越細，晶粒越均勻，塗層刀片切削性能越優異。

Theα-Al2 O3 coatings were deposited on cemented carbide substrates using CVD method with four different grain size e.SEM was employed to analysis the grain size , and then the cutting experiment of four kinds alumina coating inserts were carried out after sand blasting process .The results showed that the coating inserts had better cutting perform-ance when the α-Al2 O3 grain size becomed finer and narrower .
