目前化学镀镍磷已形成了完善的工艺,获得镍磷合金的化学镀镍槽液,一般又可分为酸性和碱性两大类,由碱性槽液中获得的镍磷镀层其含磷量均小于7％,一般介于2～5％之间,均在较低温度下操作(35～60℃),用于塑料和其他非金属基体上沉积镍层。酸性槽液中获得的镍磷 At present, electroless nickel-phosphorus plating has formed a perfect process, access to nickel-phosphorus alloy electroless nickel plating bath, generally can be divided into two major categories of acid and alkaline, obtained by the alkaline bath of nickel-phosphorus coating containing phosphorus Less than 7% of the amount, usually between 2 ~ 5%, are operating at lower temperatures (35 ~ 60 ℃), used for plastic and other non-metallic substrate deposited nickel layer. Nickel phosphorus obtained in acid bath
