提升链条性能——链条防护知识2：

进口链条防护方法二、

Zinc – galvanic    镀锌-电镀


Parts coated in an electrolytic solution by galvanic action，Three step coating process to avoid hydrogen embrittlement，Parts passivated

部件用电解的方法涂上涂层被电镀。 三步涂层的过程避免氢脆变使局部钝化




Advantages 优点

Higher abrasive resistance       较高的耐磨强度

in comparison to  mechanical coating  Higher chemical resistance

与机械涂层相比有较高的抗腐性。  



Caution areas 注意事项

De-embrittlement reduces tensile strength by 15%

氢脆变降低了15%的抗拉强度。

 

Nickel - galvanic plated     镀镍-电镀



Parts coated in an electrolytic solution by galvanic action. Two step coating process to improve corrosion and wear resistance.

部件用电解的方法涂上涂层并电镀。 二步涂层的过程提高了耐腐性及抗磨性


Advantages 优点

Higher mechanical and chemical resistance in comparison to Zinc

与镀锌相比较，较高的机械性能及耐腐性

Lower Toxicity    毒性小



Caution areas 注意事项

Coating process reduces tensile strength by 15%

涂层过程降低了15%的抗拉强度

Higher cost than Zinc

相比镀锌成本较高。
