摘要： PROBLEM TO BE SOLVED: To produce a hot dip aluminized steel sheet suppressing a decoloration, deterioration of oxidation resistance and heat resistance caused by an alloying reaction of Fe-Al and having excellent workability. SOLUTION: This hot dip aluminized steel sheet has an aluminized layer containing 3-15 mass% Si through an intermediate layer of Al-N on a steel sheet surface having α-phase surface layer occuluding 0.07-0.4 atomic % N. After applying a nitriding treatment for occuluding >=0.8 atomic % N on the surface layer by heating a hot dip coated original steel sheet in an ammonia atmosphere, this hot dip coated original steel sheet is annealed in a nitrogen- hydrogen atmosphere until the occuluding content of N on the surface layer of 5 μm from the surface is lowered to the range of 0.07-0.4 atomic %. Successively, the treated hot dip coated original steel sheet is introduced into a hot dip aluminizing bath containing 3-15 mass% Si, thus, the objective hot dip aluminized steel sheet is produced by forming the hot dip aluminized layer.

摘要： PROBLEM TO BE SOLVED: To improve the corrosion resistance of a cut edge face in a plated steel sheet by controlling the contents of Mg and Al in a pre-hot dip galvanizing based plating layer to specified ranges and moreover incorporating small amounts of Ti and B therein. SOLUTION: The compsn. of a plating layer in a hot dip Zn-Mg-Al based alloy plated steel sheet is composed of, by weight, 1 to 4% Mg, 4 to 10% Al, and the balance Zn with inevitable impurities. Or, 0.002 to 0.1% Ti and 0.001% to 0.045% B are moreover incorporated therein. Mg promotes the formation of Mg-contg. Zn based corrosion products high in protecting properties on the plating layer and reduces the corrosion rate of the plating layer itself. Moreover, a part of the corrosion products flows into the surface of the steel base in the cut edge face to suppress the corrosion of the steel base. Al in the plating layer hardly elutes from the plating layer, and Zn-Al based corrosion products are formed on the lower layer of the Zn based corrosion products high in fluidity. By the addition of Ti and B, the formation of a Zn11Mg2 phase damaging the surface appearance can be suppressed.

摘要： PROBLEM TO BE SOLVED: To prevent generation of a blackening phenomenon by chromating a galvanized layer surface of a steel plate subjecting to hot dip galvanizing containing a specified content in each of Al, Mg.
SOLUTION: A galvanized steel plate is produced so that a steel plate is dipped in a hot dip galvanizing bath containing 4.0 wt.% Al, >1.0% Mg in Zn. In a ternary composition of Zn-Al-Mg containing Al content, Mg content in Mn, in the case that the area ratio (Al-Zn-Zn
2 Mg ternary eutectic structure) of a galvanized layer surface is large, an action to suppress blackening after a chromate treatment is increased. Such structure control is made easy by containing 0.002-0.1 wt.% Ti and 0.001-0.045 wt.% B. In the case the ternary eutectic structure is 70% of the galvanized layer surface or more, generation of blackening is substantially suppressed. Further, it is preferable to adopt a coating type.
