“…We first consider the contact between a smooth plane and a nominally flat surface covered with a number of spherical asperities with the same radius and the same height z, relative to the reference plane, Figure 3.2.17 (Bhushan and Tian, 1995;Chilamakuri and Bhushan, 1997). As the surfaces are loaded together, the total displacement (normal approach) δ is equal to (z − d), where d is the current separation of the smooth surface and the reference plane of the rough surface.…”

“…The results of Fig.2 suggest that the shape and height of the laser bumps has to be chosen carefully [5]. If the height of the laser bumps is larger than the steady state flying height of the slider, wear and failure of the interface is likely to occur.…”

“…Compared to micro-patterned surfaces that have already been successfully used in various tribological applications [12][13][14][15], NDPS have several unique potential advantages for tribological applications. First, the contact area is smaller due to significantly reduced asperity size, which in turn results in a significant reduction of adhesion and friction.…”

Surface nano-patterning with Ni nanodot arrays was investigated for adhesion and friction reduction of contacting interfaces. Self-assembled anodized aluminum oxide (AAO) templates in conjunction with thermal evaporation was used to fabricate nanopatterned surfaces with ordered Ni nanodot arrays on Si substrates. Surface morphology of the Ni nanodot-patterned surfaces (NDPSs) was characterized by scanning electron microscopy (SEM). Adhesion and friction studies on a Ni NDPS and a baseline smooth Si(100) surface were conducted using a TriboIndenter employing a diamond tip with 100 lm nominal radius of curvature. The results show that the ordered Ni nanodot-patterning reduced the adhesion forces and coefficients of friction up to 92 and 83%, respectively, compared to those of the smooth silicon surface. Surprisingly, the nanoscale multi-asperity contact between the diamond tip and inhomogeneous Ni NDPSs under low loads follows a continuum contact mechanics model.
