ABSTRACT:
A conversion coating solution for treating metallic surfaces is able to form conversion coating films having excellent anticorrosiveness and giving good adhesiveness and gloss to the overcoating. The conversion coating solution has a pH value of 5.5 to 6.5 and contains 0.1 to 50 g/liter as phosphate ion of acid salts of alkali phosphates, 0.01 to 0.5 g/liter of stannous ion and 2 to 12-fold by weight as much fluorine ion as the stannous ion. The conversion coating solution may be further combined with 0.2 to 5 g/liter of at least one of pyrazole compounds, hydroxylamine compounds and hydrazine compounds.
