galling – A form of wear caused by adhesion between sliding surfaces. Materials that form a thin layer of hard oxides with high coefficients of friction, such as aluminum and stainless-steel, are especially prone to galling. (source:

In precision engineering, galling is a particular concern when contact stresses are high, such as in kinematic mounts.
