| 中文摘要: |
| 采用复合电沉积法在T91钢表面制备Ni/CrAl镀层,研究了CrAl微粒在镀层中的含量与搅拌强度、镀液pH 值、电流密度及温度的关系,确定最佳工艺参数为:电流密度2.5~4.5A/dm2,pH 值4~4.5,温度30℃。采用该工艺制备了较高CrAl含量的复合镀层,并对工艺参数影响复合电沉积的机理进行了简单探讨。 |
| 英文摘要: |
| Ni/CrAl coating was prepared on T91 steel by composite electrodeposition process. The relationship between CrAl content in coating and stirring intensity, currnt density, pH as well as temperatures were studied in Watts solution. The optimum process of composite electrodeposition of Ni/CrAl composite coating was obtained as follows: current density was 2.5~4.5 A/dm2, the temperature was held at 30℃ and pH was 4~4.5. According to this electrodeposition process high content CrAl coating was obtained. The mechanism of electrodepostion affected by process parameter was discussed in brief. |
