coated composite powder meaning in English

涂层复合粉

In this paper , we tried to get metal - coated composite powders with different particle sizes by electroless silver plating on different ceramic powders such as nano - al2o3 , micro - cenospheres and submirco - sio2 . the nano - al2o3 powder with average size about 10 to 20 nanometers was pretreated to produce catalytic activity before the electroless silver plating
本文利用化学镀的方法在不同粒径的陶瓷粉体(包括纳米al _ 2o _ 3 、微米空心玻璃微珠及亚微米级的sio _ 2 )上包覆金属银，制备不同粒径的金属包覆型复合粉体。
The ag - coated composite powder is a kind of addition agent , which is of great value in the application in the fields of conducting resin , wave - absorbing materials and optical apparatus . the importance of the composites could be attributed to the good associativity between ag and the powder and the equably coating of silver on the substrate
包银复合粉体作为一种添加剂在导电浆料、吸波材料及光学器件等领域具备很高的应用价值，银与粉体具备很好的结合性并且能均匀包覆在基体表面达到上述应用要求的一个关键。
