低温自催化镀镍实质上就是在水溶液中自催化还原镍离子的过程。它是利用镍盐溶液在强还原剂次磷酸盐的作用下,使镍离子还原成金属镍,次磷酸盐分解析出磷的,同时就能在具有催化表面的镀件上,获得镍磷合金的沉积层。对于不具备有催化表面的陶瓷、塑料、玻璃等非金属材料,则要以钯或其他贵金属膜作为其始发沉积反应的催化表
Low temperature autocatalytic nickel plating is essentially the process of autocatalytic reduction of nickel ions in aqueous solution. It is the use of nickel salt solution under the action of a strong reductant hypophosphite, the reduction of nickel ions into metallic nickel, hypophosphite decomposition of phosphorus, while the catalyst can be plated on the surface to obtain nickel-phosphorus alloy Deposits. For non-metallic materials such as ceramic, plastic, glass and the like that do not have a catalytic surface, palladium or other precious metal film should be used as a catalyst for the deposition reaction
