Fundamental investigation of micro-scale wear characteristics of ultra-fine gold wires under low contact force and long sliding distance

Experimental Research on the Determination of the Coefficient of Sliding Wear under Iron Ore Handling Conditions

“…Tables 2-3, it is obtained that ∆Td = 2.5 o C. With the obtained Tp and Td, and using equation (10), the contact temperature rise ∆T = 2.1 o C. This value is slightly higher than the maximum temperature rise estimated in Fig. 25.…”

“…To verify the experimentally measured temperature rise, the theoretical calculations are done as below. The increase of contact temperature Tc can be estimated using equation (10) [28], (10) where Tp and Td are temperature rise for particle and mid steel disk, which is respectively calculated based on the assumption that all generated heat is either dissipated at particle tip or to mild steel disk.…”

“…Yau, et al [10] obtained that the coefficient K is in the order of 10 -7 for gold wire wear by a silicon wafer using a very low normal force (5 μN).…”
