碳纤维的化学镀镍

Electroless Nickel Depositing of Carbon Fiber

提出一种碳纤维的化学镀镍技术,研究了镀层的形成过程和显微组织。结果表明:用化学镀技术在碳纤维表面镀镍是成功的,镀层均匀连续。当镀层厚度小于0.3μm时,在碳纤维表面呈不连续分布的镍膜,大于0.8μm时,在连续分布的镀层上镍以枝晶状沉积出现。应用镀镍碳纤维制造的铝基复合材料,没有观测到明显的界面反应。

An electroless nickel depositing technique of carbon fiber was presented. The procedure mechanism andmicrostructure of ntating layer were studted The resu(?)s shown f(?)a(?) (?) is (?)ss(?)e to de(?)sv an un(?)orm and cont(?)nuous nickel film on the surface of carbon fiber with an electroless technique Plating thickness less than 0.3μm showed discontinuous plating of nickel on the fiber surface, beyond 0.8μm thickness, nickei deposited in dendrite from on the continuous plating. The aluminum matrix comppsite fabricated by applying the nickel plating carbon fiber has no appreciable interaction.
