摘　　要：The instrumented scratch test,which has the advantages of simple sample preparation,high test efficiency,and low cost,has become an effective technique to investigate contact mechanisms(e.g.,contact-induced surface deformation,single-asperity contact,sliding contact,reciprocating sliding,elastic recovery,stick-slip behaviors,damage/cracking,buckling failure of films,mechanical glass frosting,abrasive machining mechanism,cutting,wear,grinding and polishing)and a large quantity of mechanical properties(e.g.,scratch resistance,tribological behavior,friction coefficient,structural integrity,hardness,strength,and fracture toughness)of various solids(e.g.,multilayer coatings,single crystals,bones,gels,polymers,ceramics,glasses,semiconductors,metals,concreates,shales,rocks,and composites)based on the measured scratch variables such as penetration depth and lateral force.
