This invention relates to thermally spray coated work rolls for use in me tal or metal alloy, e.g., aluminum alloy, sheet manufacture comprising a cyl indrical- like structure having an outer peripheral surface and a thermally sprayed coating on the outer peripheral surface of said cylindrical-like str ucture, said thermally sprayed coating comprising from about 65 to about 95 weight percent of one or more Group Vl metal carbides, and from about 5 to a bout 35 weight percent of one or more transition metals selected from chromi um, manganese, iron, cobalt and nickel. This invention also relates to a pro cess for preparing the work rolls for use in metal or metal alloy, e.g., alu minum alloy, sheet manufacture, a method for manufacturing metal or metal al loy, e.g., aluminum alloy, sheet using the thermally spray coated work rolls , and a thermal spray powder for coating the outer peripheral surface of the work rolls for use in metal or metal alloy, e.g., aluminum alloy, sheet man ufacture. |
