1. 鎳-鎢-鈷合(he)金電刷(shua)鍍(du)液的性質

  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-鈷(gu)合金(jin)電(dian)刷(shua)鍍層的(de)性質和用途

  鎳-鎢-鈷(gu)鍍(du)層硬度高，致密、孔隙(xi)少(shao)，在(zai)較高的溫度下仍具有一定的硬度，其優點是鍍(du)層的應力小，可沉積較厚的鍍(du)層，即(ji)可達0.20mm,主要用來(lai)沉積耐磨(mo)的表面層。
