镍-磷（Ni-P）涂层是许多工业应用中广泛使用的涂层，由于其具有杰出的机械和化学性质，如高硬度和良好的耐腐蚀/耐磨性质。Ni-P涂层可以通过不同的技术包括电镀和化学电镀形成。镍电镀可用于装饰工程和电铸，也可用于改善工业设备的耐腐蚀性。尽管Ni-P涂层有许多优点，但它也有不足之处。首先，为了获得较高的耐腐蚀性，Ni-P涂层必须有电沉积铬层涂于其顶部，这使其过程更加复杂。另一个实质的缺点是Ni-P涂层过程不能形成复杂形状的完整涂层。
Nickel - P (Ni-P) is coated in many industrial applications widely used in coatings, due to their outstanding mechanical and chemical properties, such as high hardness and good resistance to corrosion / wear resistance properties. Ni-P coating can be through various technologies, including formation of electroplating and chemical plating. Nickel plating can be used for decoration works and electroforming, and industrial equipment can be used to improve corrosion resistance. Although Ni-P coating has many advantages, but it also has shortcomings. First, in order to obtain a higher corrosion resistance of Ni-P electrodeposition coating must have a chrome coating the top layer, which makes it more complicated process. Another disadvantage is the essence of Ni-P coating process can not form a complete coating complex shapes.
