Chromium plating additive (fast hard chromium additive)
稀土镀铬溶液
Rare earth chromium plating solution was later called low chromium chromium plating solution, also known as low concentration chromium plating process. Strictly speaking, these two titles have different meanings, but now people are used to calling them, and it has become a common practice.
Rare earth chromium plating solution generally has three kinds of catalysts, which are rare earth, sulfuric acid and fluoride ion. The combination of sulfuric acid and fluoride ion is the catalyst for composite chromium plating mentioned above. When they exist together, the current efficiency of the chromium plating solution can be improved. After adding one or several rare earth elements to the solution, the masking ability of the plating solution can be improved; Together, allows the plating solution to operate at lower temperature conditions.
