α-Al2O3单晶活化Mo-Mn法金属化的改进

Improvement of Activated Mo-Mn Metallization for α-Al2O3 Single Crystal

采用活化Mo-Mn法对α-Al2O3单晶进行了金属化,Mo-Mn层表面容易出现玻璃相,影响Mo-Mn层电镀及焊接效果。通过对α-Al2O3单晶金属化后Mo-Mn层玻璃相的成分分析,找出Mo-Mn层与α-Al2O3单晶的粘接机理,从玻璃相中析出刚玉是关键。

Activated Mo-Mn method is used to metallizeα-Al2O3 single crystal.In metallization glass phase is easily appeared on the surface of Mo-Mn layer,which affects the electroplating and welding of Mo-Mn layer.By analyzing the composition of glass phase of Mo-Mn layer after metallization ofα-Al2O3 single crystal,the bonding mechanism between Mo-Mn layer andα-Al2O3 single crystal is found and it shows that the corundum precipitation from glass phase is the key.
