ZINC-BASED METAL PLATED STEEL SHEET EXCELLENT IN RESISTANCE TO FLAKING, SLIDING CHARACTERISTICS AND RESISTANCE TO SCORING

摘要

A zinc−based metal plated steel sheet,which has a zinc−based metal plating layer and,formed thereon,a coating film containing zinc phosphate particles in an amount of 50 wt %,and has substantially no layer formed by the reaction of the zinc phosphate particles with the zinc−based metal plating layer;and a method for producing the plated steel sheet.The zinc−based metal plated steel sheet is excellent in the resistance to flaking,and also in the sliding characteristics in an oil−free state as is seen in a portion wherein an oil film is broken off,and further in the resistance to scoring.
