摘　　要：采用化学沉积方法在石油管道基材20钢表面制备Ni-P-Ti N镀层,研究温度、Ti N粒子浓度以及p H值对Ni-P-Ti N镀层的影响,通过扫描电镜(SEM)来观察3种不同分散方式所制备镀层的表面形貌。结果表明:当温度为80℃、Ti N粒子质量浓度为2 g/L、p H值为4.8时,Ni-P-Ti N镀层的沉积速率最大,其最大值为8.7μm/h;采用机械搅拌+复合型表面活性剂工艺制备的Ni-P-Ti N镀层最为细密,仅有轻微团聚现象存在。Ni- P- Ti N composite coatings were prepared on the surface of 20 steel by electroless deposition,the effect of temperature,concentration of Ti N particle and p H value on Ni- P- Ti N composite coatings was researched,and the surface prepared by different ways was observed by scanning electron microscope. The results show that the deposition rate reaches the maximum of 8.7 μm/h when the temperature is 80 ℃,Ti N particle concentration is 2 g/L,and p H value is 4.8. The surface of the Ni-P-Ti N composite coating prepared by mechanical agitation and composite surfactant method is compact,and has only slight agglomeration.
