Abstract:
The present invention concerns a method for manufacturing wear plates of a disc chipper, whereby the wear plate is provided with a wearing surface by sintering in a furnace at a temperature of 900 - 1000 °C. Selective portions of the wear plate are strengthened by selective quenching and hardening utilizing the temperature achieved in connection with sintering.
