SOLUTION FOR FORMING MOLYBDENUM/PHOSPHORUS/SILICATE FILM AND METHOD FOR FORMING MOLYBDENUM/PHOSPHORUS/SILICATE FILM USING THE SAME

摘要

PURPOSE: A solution for forming molybdenum/phosphorus/silicate film having excellent corrosion resistance and wettability, and a method for forming molybdenum/phosphorus/silicate film using the same are provided. CONSTITUTION: The method for forming molybdenum/phosphorus/silicate film includes step of heating a solution comprising molybdenum concentration 0.4 to 4.0 g/L, phosphorus concentration 7.0 to 14 g/L, colloidal silica concentration 1.0 to 150 g/L in the temperature range of 40 to 60C; and immersing galvanized steel sheet in the solution.
