The phrase "altered surface" is correct and usable in written English.
It can be used in contexts where a surface has been changed or modified in some way, such as in art, manufacturing, or scientific discussions.
Example: "The altered surface of the material improved its adhesion properties significantly."
Alternatives: "modified surface" or "changed surface".
Furthermore, most particles in the "altered material" class have a completely altered surface.
