五金電鍍件鍍鉻與鍍鋅的不同之處

2015年06月27日
  對于剛接觸電鍍件電鍍加工需求的朋友們來說,我們的產品是需要鍍鋅還是需要鍍鉻并不是很了解,常常誤把鍍鋅的產品要求做鍍鉻。
  那么鍍鋅與鍍鉻加工到底有哪些不同呢?
  1.外觀顏色上不同:
  鍍鋅電鍍件的表面是有點青白色,光澤但不是很光亮,經過鈍化處理后,可以做成蘭白鋅、五彩鋅、黑鋅、軍綠等顏色
  鍍鉻表面都是亮白偏藍的顏色,其它的鍍鉻顏色有黑鉻。
  2.鍍鉻與鍍鋅鉻的功能不同:
  鍍鋅只是在電鍍件表面鍍上一層幾微米到十幾微米的鋅金屬,它對于鐵基來說是陽極性鍍層,具有一定的電化學防護,鍍鋅件有很好的防銹性。
  鍍鉻有鍍裝飾鉻與硬鉻之分,鍍鉻是對電鍍件表面進行電鍍幾個微米或十幾微米以上的單一鉻金屬層,具有極好的耐磨擦性能,裝飾鉻要先對產品進行鍍銅或鍍鎳后再鉻一層很溥的鉻層,它具有美觀與防護的功能,它主要針對那些有較高裝飾要求的產品進行加工使用。
  3.鍍鉻與鍍鋅的成本不同
  鍍鋅的成本價格低,而鍍鉻的成本價格較高,從電鍍加工所使用的材料和電鍍工序所使用的人工以及電鍍工藝的維護等方面,鍍鉻加工都要比鍍鋅加工的成本要高出。
