Electrogalvanizing (txias galvanizing): ib txheej zinc nyias nyias (feem ntau yog 5-20μμm) yog tsim ntawm cov hlau saum npoo av los ntawm electrolysis. Nws muaj cov tsos du tab sis tsis muaj zog corrosion tsis kam. Nws yog tsuas yog siv nyob rau hauv cov ntawv thov kev lag luam xws li rooj tog thiab khoom siv hluav taws xob.
Kub - dip galvanizing: cov hlau yog raus hauv Molersten Zinc (kwv yees li 450 degree) los tsim cov txheej txheej tuab (60-300μm). Nws muaj cov kev tiv thaiv corrosion thiab yog qhov tsim nyog rau sab nraum zoov cov qauv xws li yees thiab pipelines.
Alloyed galvanizing (zinc-iron alloy coating): After hot-dip galvanizing, a high-temperature diffusion treatment is performed to form an alloy between the coating and the substrate, improving wear resistance. Nws yog feem ntau siv nyob rau hauv audotive steel los xij.
