文摘	用化学沉积方法制备了Ni—P—TiO_2纳米复合镀层，通过XRD、SEM、TEM和EDS对纳米复合镀层进行了表征，分析了在3．5％NaCl溶液中TiO_2纳米颗粒浓度对纳米复合镀层的耐蚀性能影响，研究了热处理温度对复合镀层显微硬度的影响。结果表明：所得复合镀层中纳米粒子的复合量可达到11．33％；在3．5％NaCl溶液中，当TiO_2浓度为8g／L时复合镀层腐蚀电位最高，耐蚀性能最好；在镀态或热处理后，复合镀层的硬度都明显高于Ni—P合金镀层，且经过400℃热处理后，复合镀层的硬度高达Hv1160。
其他语种文摘	Ni-P-TiO_2 nano-composite coatings were prepared by electroless deposition. The nano-composite coatings were characterized by XRD, SEM, TEM and EDS. Influences of TiO_2 bath concentration on the corrosion resistance in 3.5 % NaCl and effects of heat treatment temperature on the microhardness of composite coatings were investigated. The results showed that the content of TiO_2 was 11.33wt%; When the TiO_2 bath concentration was 8g/L, the corrosion potential of composite coatings was maximum and the corrosion resistance was best in 3.5% NaCl solution; The microhardness of composite coatings was obviously higher than Ni-P alloy deposits, and after heat treatment at 400℃, the hardness of the composite coatings was as high as Hv1160.
