合成二乙撑三胺三甲撑基膦酸（DETAPP），并将其添加到低温磷化液中，发现添加DETAPP能明显地提高磷化后钢铁的耐蚀性和耐磨性，机理是该有机磷酸能与Zn2+、Fe3+等螯会附集于钢铁表面形成一层耐蚀性的膜。
Synthesis of diethylenetriamine trimethylene phosphonic acid (DETAPP), and added to the low temperature phosphating solution, found that the addition of DETAPP can significantly improve the phosphating steel corrosion resistance and wear resistance, the mechanism of the organic Phosphoric acid and Zn2 +, Fe3 + and other chelates will be attached to the steel surface to form a corrosion-resistant film.
