Description

EXAMPLE

[0201] Plated steels relating to Table 1a to Table 5c were manufactured and performance evaluations were performed.

[0202] For formulation of plating baths of various types, pure metals (purity of 4N or higher) were formulated to prepare the baths. As for components of a plating alloy, Fe powder was added after the bath is prepared so that an Fe concentration did not increase during the test. As for components of a plated steel sheet, a plated layer was peeled off with hydrochloric acid in which IBIT manufactured by Asahi Chemical Industry Co., Ltd. was dissolved as an inhibitor, and an adhesion amount was measured. As for components of the plated layer, a component analysis of the peeled-off components was performed using an ICP emission spectrophotometer manufactured by Shimadzu Corporation.

[0203] Hot-rolled original sheets (3.2 mm) of 180×100 size were used as original sheets of the plated steel, and a batch-type hot-dip plating simulator (manufactured by RHESCA Co., Ltd.) was used. All of them are SS400 (general steel). A K thermocouple was attached to a part of each of the plated steel sheets and annealed at 800° C. in an N.sub.2 (H2-5% reduction) atmosphere to sufficiently reduce a surface of the plating original sheet, the plated steel sheet was iimmersed in the plating bath for 3 seconds and then pulled up, and a plating thickness was made to be 25 to 30 μm by N.sub.2 gas wiping. After the plated steel sheets were pulled up, plated steels were manufactured under various cooling conditions and reheating conditions described in Table 1a to Table 1c. Further, “-” in the table means that reheating was not performed. Also, the underlined one indicates that it is outside the scope of the present invention.

[0204] The plated steel after plating was cut into 20 mm square, a high-angle X-ray diffractometer manufactured by Rigaku Corporation (model number RINT-TTR III) with a goniometer TTR (horizontal goniometer), a Kβ filter slit width of 0.05 mm, a longitudinal limiting slit width of 2 mm, a light receiving slit width of 8 mm, and a light receiving slit 2 open was used, and measurement was performed with a scan speed of 5 deg./min, a step width of 0.01 deg., and a scan axis of 2θ (5 to 90°) as measurement conditions to obtain a cps intensity at each angle. An X-ray source was Cu-Kα rays using Cu as a target, and an X-ray output was set at a voltage of 40 kV and a current of 150 mA.

[0205] (Corrosion Resistance of Planar Portion)

[0206] As an index for evaluating corrosion resistance of the planar portion, the plating steel sheet was cut into 100×50 mm sizes and these were subjected to 60 cycles of corrosion tests in a combined cycle corrosion test (JASO M609-91). Corrosion weight loss after 90 cycles was evaluated, and superiority or inferiority was determined according to criteria of S, AAA, AA, A, and B according to the following levels. Further, S, AAA, AA, and A were regarded as passing.

[0207] S: Corrosion weight loss is less than 50 g/m.sup.2

[0208] AAA: Corrosion weight loss is 50 g/m.sup.2 or more and 60 g/m.sup.2 or less

[0209] AA: Corrosion weight loss is 60 g/m.sup.2 or more and 70 g/m.sup.2 or less

[0210] A: Corrosion weight loss is more than 70 g/m.sup.2 and 80 g/m.sup.2 or less

[0211] B: Corrosion weight loss is more than 80 g/m.sup.2

[0212] (Sacrificial Corrosion Resistance)

[0213] In order to evaluate sacrificial corrosion resistance, three pieces of cut end surfaces of samples with a 100×50 mm size were coated with an epoxy-based resin for waterproof treatment. An open end surface was defined as one end surface, and burr directions were unified. Each of these samples was subjected to the same JASO test as described above, and a red rust area ratio after 90 cycles of JASO was evaluated. A photograph was taken from an end surface direction, and superiority or inferiority was determined according to criteria of S, AAA, A, and B according to the following levels for a cross section (approximately 3.2 mm×100 mm) thereof. S, AAA, and A were regarded as passing.

[0214] S: Red rust area ratio is less than 30%

[0215] AAA: Red rust area ratio is 30% or more and less than 50%

[0216] A: Red rust area ratio is 50% or more and less than 70%

[0217] B: Red rust area ratio is 70% or more

[0218] (Corrosion Resistance of Bent Portion)

[0219] The plated steel sheet was bent at 1800 using a bender, then an inner surface was crushed to a thickness of one sheet by a hand press, and thereby a 1T bending test piece (t=3.2) was prepared. A coating treatment was performed around the bent portion to completely repair a base steel exposed portion. With a T-bending top portion facing upward, the test piece was put into the combined cycle corrosion test (JASO M609-91). A period until the red rust area ratio of the top portion reached 5% was evaluated. Evaluation criteria were as follows. 8, AAA, AA, and A were regarded as passing.

[0220] S: more than 135 cycles

[0221] AAA: more than 105 cycles and 135 cycles or less

[0222] AA: more than 75 cycles and 105 cycles or less

[0223] A: 60 cycles or more and 75 cycles or less

[0224] B: less than 60 cycles
