I am not aware of any direct model in ANSYS for simulating interaction between corroded surfaces. This may need some Programming effort on your side, utilizing User Programable Features (UPF's) which allow users to model such a complex interaction. Have a look at this interesting article https://www.ansys.com/blog/how-do-adhesives-work . You can also define your own friction model with the user programmable friction subroutine, USERFRIC. Check - Writing Your Own Friction Law part of the Contact Technology Guide
