On the empirical law of adhesive wear
WebAccording to the Archard’s law of adhesive wear, the wear volume (Q) is proportional to the normal force (W), the sliding distance (L), and inversely proportional to the hardness of … Web4 de abr. de 2024 · For that, the Archard equation is first formally divided by the area : (1) where are the local wear depth and contact pressures. Further, this equation is differentiated in time and the equation takes the following form: (2) where is the sliding speed. This equation can be used to calculate wear locally if the contact pressure is known and is ...
