Experimental Research on Mechanical Characteristics in the Process of Nanoscale Sliding Contact

Abstract:

The experiment of mechanical characteristics of sliding contact in nano-scale was researched using nano-indenter. The displacement-friction curves with different loads and sliding velocities were given through the contact effect between diamond indenter and mono-crystalline silicon test-coupon. The three-dimensional AFM morphologies were obtained through scanning contact area by AFM. The research shows that the contact-force and friction increase along with the increment of loads, in condition of sliding with different loads. The friction increases along with the increment of sliding velocity, in condition of different sliding velocities. Otherwise, furrow destruction along with obvious plastic flow is generated with low sliding velocity (100μm/s). However, the oddments accumulate obviously on the verge of nick with high sliding velocity (above 100μm/s), and the phenomenon of oddments accumulating is more obvious along with the increment of sliding velocity.
