Effect of Surface Topography Parameters on Friction and Wear of Random Rough Surface

“…Figure 4 shows the relationship between the three-dimensional characterization parameters Sa , Sku , Vvv , and Vvc and the friction coefficient at a sliding speed of 0.5 mm/s. It can be seen from Figure 3 that with the increase in the height parameter Sa , the functional parameters, Sku , Vvv , and Vvc , and the friction coefficient first decrease and then increase, and the change in the friction coefficient produces a critical point, which is related to the critical characteristics of the surface topography [23,24]. In addition, as the contact pressure increases, some of the friction coefficient gradually decreases.…”

Impact of Aggregation on the Percolation Anisotropy on a Square Lattice in an Elongated Geometry

“…Other correlated percolation models were studied in [12][13][14][15]. In a 2𝑑 correlated percolation model, the attractive interactions between near-neighbor occupied sites result in the formation of a structure reminiscent of discontinuous metal films [12].…”

“…In the granular correlated percolation model, the initial seeds are deposited on the substrate, and the grains are growing around them [14]. The correlated percolation for the deposition on a heterogeneous substrate with two types of sites with different energies of attraction was studied in [15].…”
