ABSTRACT:
A method for enhancing the thermal quenching of a metal surface comprises treating the metal surface with a complex phosphate acid ester. The metal surface is simultaneously or subsequently treated with a thermal quenching fluid. The method is particularly adapted for use in thermal quenching of aluminum and aluminum alloy surfaces. The complex phosphate acid ester has the formula: ##STR1##
