摘要:
A phosphate coating apparatus for depositing a phosphate coating on a metal material by electrolyzing the metal material in a predetermined electrolysis solution includes a positive electrode and a negative electrode, of which one electrode being disposed in contact with the metal material and the other electrode being disposed away from the metal material with a predetermined distance, and the other electrode being formed into a tubular shape so as to cover the entire length of the metal material.
