钕铁硼的镀层Neodymium iron boron coating

由于钕铁硼磁钢基体易氧化和易受腐蚀，为了保护磁钢，一般需要不同的镀层，常用的镀层有：镍铜镍、蓝白锌、彩锌、环氧、磷化、特富龙...... Because the matrix of Nd-Fe-B magnetic steel is easy to be oxidized and corroded, different coatings are generally required to protect the magnetic steel. The commonly used coatings are: nickel copper nickel, blue white zinc, color zinc, epoxy, phosphating, Teflon

镍铜镍镀层磁钢Nickel copper nickel coated magnetic steel

镍铜镍镀层具有优秀的耐腐蚀性能、硬度、耐磨性等综合物理化学性能，暴露于复杂的大气环境中，保证外观与内在性能的长期稳定和较长的使用寿命。对于钕铁硼来说，是一种最常见的镀层之一。 Nickel copper nickel coating has excellent corrosion resistance, hardness, wear resistance and other comprehensive physical and chemical properties. It is exposed to complex atmospheric environment to ensure long-term stability of appearance and internal performance and long service life. Neodymium iron boron is one of the most common coatings.

蓝白锌镀层磁钢Blue white zinc coated magnetic steel

锌镀层一般较薄，防腐性相对较好，镀层经钝化后外观漂亮，色泽较美观，磁钢中心与边角镀层的“骨头效应”不明显，对产品公差较紧产品也可满足。可使用于抗短期污染变色的有限腐蚀性场合。 The zinc coating is generally thin and has relatively good corrosion resistance. After passivation, the coating has a beautiful appearance and beautiful color. The "bone effect" of the coating at the center and corners of magnetic steel is not obvious, which can also be met for products with tight product tolerance. It can be used in limited corrosive occasions with resistance to short-term pollution and discoloration.

彩锌镀层磁钢Color zinc coated magnetic steel

彩锌镀层具有普通蓝白锌镀层的特点外，具有比蓝白锌镀层更高的防腐性。可使用于较为苛刻的气氛环境中。 Color zinc coating has the characteristics of ordinary blue and white zinc coating, and has higher corrosion resistance than blue and white zinc coating. It can be used in harsh atmosphere.

环氧树脂镀层磁钢Epoxy resin coated magnetic steel

环氧树脂具有良好的物理、化学性能，对金属和非金属材料的表面具有优异的粘接强度，介电性能良好，变定收缩率小，制品尺寸稳定性好，硬度高，柔韧性较好，对碱及大部分溶剂稳定。我司采用电镀镍铜之后再涂装环氧树脂工艺，产品具有优异的粘结能力和耐腐蚀能力。 Epoxy resin has good physical and chemical properties, excellent bonding strength to the surface of metal and non-metallic materials, good dielectric properties, small variable shrinkage, good dimensional stability, high hardness, good flexibility, and stable to alkali and most solvents. Our company adopts the process of electroplating nickel copper and then coating epoxy resin. The products have excellent bonding ability and corrosion resistance.

磷化镀层磁钢Phosphate coated magnetic steel

磷化用于给基体金属提供保护，在一定程度上防止金属被腐蚀，具有无镀层厚度的特点。在涂漆前打底，可提高漆膜层的附着力与防腐蚀能力。 Phosphating is used to protect the base metal and prevent the metal from corrosion to a certain extent. It has the characteristics of no coating thickness. Priming before painting can improve the adhesion and anti-corrosion ability of the paint film.

特氟龙镀层磁钢Teflon coated magnetic steel

特氟龙具有独特优异的耐热（180～260℃），耐低温（－200℃）及介电性能等。它具有最高的工作温度（260℃）和最好的化学稳定性，除熔融的碱金属、高温和二氟化氛外，尚无其他化学物质能对它产生侵蚀。它还有优良的耐候性，一般可在户外使用10年以上。具有低的摩擦系数，其润滑性，特别是自润滑 Teflon has unique and excellent heat resistance (180 ~ 260 ℃), low temperature resistance (- 200 ℃) and dielectric properties. It has the highest working temperature (260 ℃) and the best chemical stability. Except for molten alkali metal, high temperature and difluorination atmosphere, no other chemical substances can erode it. It also has excellent weather resistance and can be used outdoors for more than 10 years. It has low friction coefficient and its lubricity, especially self lubrication
