化工行业产品进行化学镀镍用处是什么?
来源:http://www.jnjrh.com 日期:2019-10-02 发布人:admin
化学镀镍是化学镀运用为普遍的一种方法,所用恢复剂有盐、肼、和二甲基胺等。
Electroless nickel plating is the most common method of electroless plating. The restorers used are salt, hydrazine and dimethylamine.
如今国内出产上大多选用钠作恢复剂,和二甲基胺因报价较贵,只需少数运用。
Nowadays, sodium is mostly used as Restorer in domestic production, and dimethylamine is more expensive, only a few applications are needed.
1.镀层的用途
1. Application of Coating
化学镀镍层的结晶详尽,孔隙率低,硬度高,镀层平均,可焊性好,镀液深镀才干好,化学稳定性高,如今已普遍用于电子、航空、航天、机械、精密仪器、日用五金、电器和化学工业中。

Electroless nickel plating is characterized by detailed crystallization, low porosity, high hardness, average coating, good solderability, good deep plating ability and high chemical stability. It has been widely used in electronics, aviation, aerospace, machinery, precision instruments, daily hardware, electrical appliances and chemical industry.
非金属资料上运用化学镀镍越来越多,特别是塑料制品经化学镀镍后即可按惯例的电镀方法镀上所需的金属镀层,获得与金属相同的外观。塑料电镀产品已普遍用于电子元件、家用电器、日用工业品等。
More and more electroless nickel plating is used in non-metallic materials, especially for plastic products. After electroless nickel plating, the required metal coating can be obtained by conventional electroplating method, and the same appearance as metal can be obtained. Plastic electroplating products have been widely used in electronic components, household appliances, daily industrial products and so on.
化学镀镍在原子能工业,如出产核燃料体系中的零件和容器以及火箭、、喷气式发起机的零部件上已选用。
Electroless nickel plating has been used in the atomic energy industry, such as parts and containers in the production of nuclear fuel system and parts of rocket, jet engine.
化工设备中紧缩机等的零部件为防腐蚀、抗磨,而用化学镀镍层是很有利的。
Compressors and other parts of chemical equipment are anti-corrosion and anti-wear, and electroless nickel plating is very advantageous.
化学镀镍层还能改良铝、铜、不锈钢资料的焊接功用,削减滚动局部的磨耗,削减不锈钢与钛合金的应力腐蚀。
Electroless nickel plating can also improve the welding function of aluminium, copper and stainless steel, reduce rolling local wear, and reduce stress corrosion of stainless steel and titanium alloy.
对镀层尺度请求精确的精密零件和几许外形杂乱的零件的深孔、盲孔、腔体的内外表,用化学镀镍能得到与表面面相同厚度的镀层。
Electroless nickel plating can obtain coatings of the same thickness as the surface of precise parts and deep holes, blind holes and inner and outer surfaces of several parts with disorderly shapes.
对请求高硬度、耐磨的零件,可用化学镀镍替代镀硬铬。
For parts requiring high hardness and wear resistance, electroless nickel plating can be used instead of hard chromium plating.
