Hello guys, in my work we have a problem detected in the clutch drum (automatic gearbox) : indentations in the contact of the clutch drum and the circular plate, wefound that the hardness of the circular plate is higher than the clutch drum, do you guys have some propositions to solve this?

Welcome to PF.

The more details you can give, the better responses you will get. Can you link to information about this clutch mechanism? How much power is being transmitted through this gearbox? Who manufactures this clutch? Have you asked them this question?
