On the competition between adhesive and surface effects in the nanocontact properties of an exponentially graded coating

作者：

Highlights：

• The relation between surface and adhesive effects can be identified as competitive.

• Higher adhesive energy leads to larger contact, pull-off force, adhesion and pressure.

• Higher Tabor’s parameter leads to larger contact, pull-off force and pressure but smaller adhesion.

• Surface effects lead to smaller contact and pressure but larger pull-off force and adhesion.

• Surface effects slow down the transition from MD to JKR adhesive contact.
