Abstract
A sintered gearwheel is described having teeth () which, in the flank and root region (), comprise a compacted surface layer () which is continuous in the transition portion () between the flank and root region () and has a residual porosity of less than 10%. In order to increase the load-bearing capacity it is proposed that the compacted surface layer () is formed with a lower thickness in the transitional portion () between the flank and root region () than in the adjacent flank and root regions ().
