表面活性剂及施镀工艺在化学镀镍施镀过程中具有重要作用.实验以PZT-4陶瓷为基体,在碱性镀液中施镀,获得Ni-P合金镀层,研究了 OP乳化剂对PZT-4陶瓷表面化学镀镍的影响.通过镀速、镀层耐腐蚀性、表面形貌、元素组成、导电性及物相结构测试,对施镀过程中镀液的温度、酸度及 OP 乳化剂浓度对镀层性能的影响作了研究.结果表明,当镀液中 OP乳化剂浓度为15~25 mg/L 时镀层综合性能较好,施镀温度范围为40~45℃,pH 值范围为8．5~9．0时镀速及外观质量较好.%The surfactant and plating technology played an important role in the process of electroless nickel plating.The experiment based on PZT-4 ceramic plating in the alkaline solution to obtain Ni-P alloy coating. The influence of OP emulsifier on PZT-4 ceramic surface chemical nickel plating was discussed.Using plating speed,coating corrosion resistance,surface morphology,element composition,electrical conductivity test,and the phase structure of plating technology to study the effects of temperature,acidity and OP emulsifier concen-tration on the properties of the coating.Results show that when the OP emulsifier concentration in plating solu-tion is 15-25 mg/L,the coating has good performance,the best plating process condition range as follows:40-45 ℃ as the plating temperature range,8.5-9.0 as the pH value range.
