1. 鎳-鎢-鈷合(he)金電刷鍍液的(de)性質

  鎳-鎢-鈷合金電刷鍍液是在鎳-鎢合金鍍液的基礎上加入少量的硫酸鈷等成分組成的鎳-鎢-鈷鍍液。它是酸性鍍液，pH=1.2~2.4,深綠色，20℃時相對密度為1.29,電導率為2.052 Ω^-1·cm^-1。

2. 鎳-鎢(wu)-鈷合金電刷鍍層的性(xing)質和(he)用途

  鎳-鎢-鈷鍍(du)(du)層(ceng)硬度高，致密、孔隙少(shao)，在較高的(de)(de)溫度下仍具(ju)有一定的(de)(de)硬度，其優(you)點(dian)是鍍(du)(du)層(ceng)的(de)(de)應力(li)小，可(ke)沉積較厚(hou)的(de)(de)鍍(du)(du)層(ceng)，即可(ke)達(da)0.20mm,主要用來沉積耐磨的(de)(de)表(biao)面層(ceng)。
