    摘要: A flame-sprayed layer comprising 1.0 to 1.5% by weight of C, 2.0 to 4.0% by weight of B, 2.0 to 4.0% by weight of Si, 1.0 to 6.0% by weight of Fe, 10.0 to 16.0% by weight of W, 5.0 to 21.0% by weight of Cr and 10.0 to 15.0% by weight of Ni, with the balance being Co, is formed on the surface of an immersion member for a hot dip galvanizing bath. This surface layer has improved corrosion resistance and abrasion resistance and an excellent peeling resistance (adhesion), and the life of the immersion member is prolonged and a galvanization product having a uniform quality and having no flaws can be prepared by using an immersion member having this flame-sprayed surface layer. These effects are enhanced when the formed flame-sprayed layer is heated at a temperature-elevating rate of 10.degree. to 100.degree. C./hr and maintained at a pre-heating temperature of 300.degree. to 600.degree. C. for at least 0.5 hour, the fusing treatment is conducted at a temperature of at least 1000.degree. C. for up to 30 minutes once or twice, the temperature is dropped, a soaking treatment is carried out at 500.degree. to 800.degree. C. for at least 1 hour and a cooling treatment is then carried out at a temperature-dropping rate of 10.degree. to 50.degree. C./hr.
