<p>The method involves providing multiple disks (4, 4', 4'') that exhibit a contour of a turbine wheel i.e. Pelton wheel (1), where the disks are successively layered. The disks are welded together or connected with one another by brazing contact areas between the disks. An abrasion resistant layer is applied to a wing or a Pelton cup (2) of the turbine wheel by flame spraying or plasma spraying. The disks are of different thicknesses. The disks are produced from metal sheet panels or plates by laser cutting or flame cutting. An independent claim is also included for a turbine wheel i.e. Pelton wheel, comprising multiple disks.</p> |
