Abstract:
Quick surface metallization of titania powder was carried out by electroless chemical deposition of nickel. The fabricated product was characterized by XRD, SEM, FTIR and cross-section metallography. The analysis results show that titania particles are completely coated by a thin nickel shell about 600 nm thick, composed of nano-sized crystalline nickel particles. Mechanism of nickel chemical deposition on nano powder is proposed.
采用镍的无电子化学沉积方法研究了纳米二氧化钛粉末表面的快速金属化.所得产物经XRD、SEM、FTIR及剖面金相显微术进行了表征.分析结果表明二氧化钛粒子完全被金属镍包覆, 金属壳层600 nm厚, 由镍的纳米晶粒组成.由此提出了镍在纳米粉末上的化学沉积机理.
