摘要 |
A press roll such as the center roll of a press or the back-up roll of an extended-nip press roll, used in a pulp, paper, board or finishing machine, has a coating with an intermediate sealed layer. The corrosion resistance and impermeability of the roll coating, particularly of such a coating that is made by thermal spraying, can be improved by way of sealing. The coating comprises a porous outermost surface layer made out of a ceramic or ceramic-metal material applied by thermal spraying and at least one sealed layer situated between the outermost surface layer and the roll mantle. |
