Stainless steels such as 2Cr stainless steel are generally used, but when such materials come into contact with the object to be plated, their edges scratch the surface of the immersed member, causing local corrosion. In order to eliminate these problems, the present inventors have developed a special plated product, which has the major problem of being transferred to plated products and resulting in frequent product defects. As disclosed in Japanese Patent Publication No. 59-153875, W: lO~3゛0%, Ni: 15% in weight%
We have previously developed a roll in a hot-dip galvanizing bath in which a thermally sprayed layer made of the following Co-based self-fluxing alloy is formed on the surface of a base material.

界において強く要望されていた。(Problems to be Solved by the Invention) However, although the hot-dip galvanizing bath roll' as described above is far superior to conventional stainless steel rolls in terms of wear resistance and corrosion resistance, the bath composition is As a result, an alloy layer is formed by reacting with zinc, and local alloying with zinc is observed, unevenness occurs on the roll surface, and these unevenness cause scratches on the surface of the plated product, resulting in a lifespan of about one month. There has been a strong demand in the industry for better corrosion resistance and durability.

することがわかった。(Example 1) As shown in the drawings, three types of alloys having composition ranges used in the present invention were thermally sprayed on the surface of a roller as a first immersion member (11).
Hot-dip galvanizing of automotive steel sheets is carried out by a conventional method by passing a strip (4), which is a material for automotive steel sheets, through a hot-dip galvanizing bath (3) in which the welded roll is immersed. When the treatment was carried out, alloy layer formation and local alloying with zinc did not occur, resulting in a remarkable extension of service life and an improvement in the quality of the rust-proof steel sheet for automobiles. Table 1 shows the quality and usage results of the immersed member between this example and the conventional one.As is clear from this table, the present invention has fewer surface abnormalities of the immersed member than the conventional one. (For this reason, it was found that the present invention exhibits an excellent effect as a countermeasure against dross entrapment and localized scratches caused by alloying with zinc, which were problems in conventional products.
