- 2價金屬鹽 添加된 縮合燐酸鹽의 電解浴에서 生成된 알루미늄板의 酸化皮膜두께는 15%黃酸 電解浴에서 보다 減少되나 이때 生成된 알루미늄皮膜은 두께는 얇지만 黃酸浴에서 보다 耐蝕性 및 耐磨耗性이 큰 硬質의 酸化皮膜 이었다.
When condensed phosphates were added with bivalency metallic ions (Ni^(+2), Zn^(+2)), the thickness of coatings were thinner, than 15% H_2SO_4 bath, but the variations of thickness were small. As a result, it was found out the anodic oxide coatings applied to aluminum plates in 15% H_2SO_4-sodium phosphates, and added bivalency metallic ions bath were thinner, but closer and harder than those in 15% H_2SO_4 eletrolytes bath.
