工艺参数对铜基Ni—P-PTFE化学复合镀的影响

研究了单个工艺参数对铜基Ni—P—PTFE化学复合镀的影响．实验结果显示，随着表面活性剂质量浓度增加，镀层厚度减小，镀层中聚四氟乙烯（PTFE）质量分数先升后降，Ni、P质量分数则有少量增加，C质量分数减少；镀液pH值增大时，镀层厚度和PTFE质量分数增加，M和P质量分数出现小幅度的波动，C质量分数则在3．47％～4．38％间波动；随着PTFE乳液体积分数增加，镀层厚度下降．PTFE乳液浓度为13mL／L时，镀层PTFE质量分数出现最大值3．42％，Ni和P元素的质量分数随PTFE乳液浓度的增大而减小，C质量分数则先减小后增大；镀层厚度随温度上升而大幅增长，温度为85℃时，镀层PrrFE质量分数出现最大值7．26％，镀层Nj质量分数随温度上升而下降，P质量分数在9．82％-10．95％间波动，C质量分数则随施镀温度升高而减少．

Effects of Technological Parameters on Ni-P-PTFE Composite Copper Coating

Effects of technological parameters on copper by Ni-P- polytetrafluoroethylene （PTFE） coating were investigated. Experimental results demonstrate that with the increase of surfactant concentration and the decrease of the coating thickness, the PTFE content first ascends and then declines while Ni and P content varies in a small range, and the C content declines. When the pH value increases, the coating grows thicker, the PTFE content ascends while Ni and P content varies in a small scale and the C content varies between 3.47% and 4. 38%. As the PTFE concentration increases, the coating thickness de- clines, the maximum PTFE content 3.42% appears at the PTFE concentration 13 mL/L while the Ni and P content in the coating decreases, the C content first drops and then increases. Moreover, the coating thickness increases greatly under a higher bath temperature. The maximum value of PTFE content is 7.26% at 85℃. The Ni content decreases at a higher temperature and the P content varies between 9.82% and 10. 95%. And the C content decreases with the increase of the temperature.
