What can affect the hardness of CAR (layer thickness)?

Hello,

i did a nanoidentation experiment :

1 CAR with 3 different layer thicknesses.

My results show that the CAR is harder when it has thicker layer..

I can't find the reason in the literature..

Do you now what could be the reason??

Is there any literature for this?

best regards
