A gear wheel is formed from a pressed and sintered powder metal blank in which the metal powder comprises an admixture of iron powder and at least one alloying addition and the gear wheel is surface hardened by densifying at least the tooth root and flank regions to establish densification in the range of 90 to 100 per cent of full theoretical density to a depth of at least 380 and up to about 1,000 microns.

On fabrique une roue dentée à partir d'une ébauche de métal en poudre comprimée et frittée en trempant la surface des régions de la denture, de la base et des flancs pour augmenter la densité de 90 à 100 % à une profondeur d'au moins 380 microns.
