Abstract
PURPOSE: To enhance spot weldability by coating a zinc (alloy) plated layer formed on a steel plate by a metal oxide film.
CONSTITUTION: To a surface of a corrosion resistant steel plate plated by zinc or zinc alloy such as Zn-Ni alloy, a suspension containing metal oxide such as Al2O3, SiO2, TiO2 or the like is contacted to adhere these oxide film up to 0.5g/m2 max. Because electric resistance of the obtained steel plate is high during contact time, electric current concentration and heat generating amount are increased and spot weldability is improved.
