ENP是什么的缩写? enp是一种涂层名称,“化学镀镍磷”, electroless nickel plating ,广泛用于球阀等表面。 http:///wiki/electroless_nickel_plating electroless nickel plating (en) is an auto-catalytic chemical technique used to deposit a layer of nickel-phosphorus or nickel-boron alloy on a solid workpiece, such as metals or plastic. the process relies on the presence of a reducing agent, for example hydrated sodium hypophosphite (napo2h2·h2o) which reacts with the metal ions to deposit metal. the alloys with different percentage of phosphorus, ranging from 2-5 (low phosphorus) to up to 11-14 (high phosphorus) are possible. the metallurgical properties of alloys depend on the percentage of phosphorus.查看更多
