... range from 30 deg to 70 deg. Nanoscratch with ramp loading was performed at low loads. The scratch test with ramp normal loading was analyzed for failure of coating in three ranges, viz., range A, range B, and range C. Scratch test result shows that the peeling of coating occurred at the normal load...

...Raja R. Katta; Andreas A. Polycarpou; Sung-Chang Lee; Mike Suk Scratch-related magnetic signal degradation can occur during magnetic storage hard disk drive operations when the read-write heads contact the spinning multilayer disks. To investigate this phenomenon, controlled nanoscratch experiments...

...S. Ingole; A. Schwartzman; H. Liang Investigation of abrasive wear at the nanometer-length scale is presented on single crystalline (001) and amorphous silicon. Experiments were performed using nanoindentation and nanoscratch approaches. Surface characterization was carried out using an atomic...
