发明名称 Sintered Gear Element Featuring Locally Selective Surface Compression
摘要 A method for producing an at least partially surface-densified metallic toothed element comprising a densified sintering material, in order to improve a strength profile, a preform of the toothed element being produced with a locally selective oversize profile relative to a final size of the toothed element and being rolled to the final size by means of at least one rolling die, the toothed element being densified in locally varied manner at least in the region of at least one flank and/or one root of a tooth of the toothed element to produce a densified outer layer.
