Abstract
(EN)
[Problem] To improve molten aluminum erosion resistance, high-temperature oxidation resistance and high-temperature abrasion resistance. [Solution] A sink roll which can be used in a metal bath containing Al in an amount of at least 50% by mass, the sink roll being characterized in that a dual-layer thermal-sprayed coating film composed of an under-coat layer and a top-coat layer is formed on the roll surface of the sink roll, the under-coat layer is a cermet thermal-sprayed coating film which comprises a first boride comprising at least WB, WCoB and W2CoB2, a second boride comprising at least one of borides of Cr, Zr and Ti and a remainder made up by a cobalt-based alloy that does not contain nickel in an amount of 5% by mass or more, the top-coat layer is a ceramic thermal-sprayed coating film comprising an Al2O3-type oxide, the content of the first boride is 55 to 75% by mass inclusive, the content of the second boride is 5 to 15% by mass inclusive and the content of B is 5.0 to 7.0% by mass inclusive all relative to 100% by mass of the cermet thermal-sprayed coating film, and the content of Al2O3 is 60% by mass or more relative to 100% by mass of the ceramic thermal-sprayed coating film.
