摘要： A zinc phosphate-type conversion film having microfine-sized crystals is formed on metal surfaces using a conversion treatment bath that contains zinc ions and phosphate ions along with 50 to 1500 ppm of an organoperoxide conversion accelerator, and optionally surfactant. Surface-conditioning treatments can be omitted from this method. The presence of the surfactant makes possible simultaneous execution of surface cleaning and conversion treatment
