Experimental study of slider-disk interactions monitored by an off-resonance mode electrostatic force manipulation methodology

Study of slider-disk degradation due to interactions at contact regime is critical as slider-disk interface approaches lubricant surfing regime. In this paper, two distinct contact stages are identified and monitored by an off-resonance electrostatic force manipulation methodology. Results and analyses of slider-disk degradation are discussed. It is found that stage 2 contact produces significant wear on slider and disk.
