Abstract
The peripheral teeth of a gear body are made of alloy tool steel and coated with a manganese-phosphate-treated layer and then with a solid lubricating film. The alloy tool steel of which the teeth of the gear body cooperates with the manganese phosphate layer to act on the solid lubricating film. The taking-in force of the solid lubricating film can be thus increased at the surface thereof. The bonding strength of the solid lubricating film can be increased as well. This can prevent the solid lubricating films on teeth of the two gear bodies engaged from being separated from each other.
