In order to provide information about the basic processes involved in the wear of metals, a detailed study has been made of a severe type of wear. The particular system chosen was the wear of brass against a harder material under conditions in which the debris produced is metallic. Using radioactivity methods, transfer of metal between the rubbing surfaces was determined concurrently with measurements of the total wear. In experiments at various loads, the relationship between the rates of transfer and wear was studied. Particle-size distributions of the wear debris were obtained and compared with size distributions of the transferred fragments. It is concluded that wear occurs via a layer of transferred metal and that there is no direct production of loose wear particles. The wear process has at least two distinct stages; namely, the removal of metal from the wearing surface by transfer, and the formation of wear debris from the transferred layer on the opposing member. The magnitude of the applied load determines primarily the scale of the phenomena rather than the rate at which they occur.

Abstract. Traffic emissions are a significant source of airborne particulate matter (PM) in ambient environments. These emissions contain high abundance of toxic metals and thus pose adverse effects on human health. Size-fractionated aerosol samples were collected from May to September 2013 by using micro-orifice uniform deposited impactor (MOUDI). Sample collection was conducted simultaneously at the inlet and outlet sites of Hsuehshan Tunnel in northern Taiwan, which is the second longest freeway tunnel (12.9 km) in Asia. Such endeavor aims to characterize the chemical constituents, size distributions, and fingerprinting ratios, as well as the emission factors of particulate metals emitted by vehicle fleets. A total of 36 metals in size-resolved aerosols were determined through inductively coupled plasma mass spectrometry. Three major groups, namely, tailpipe emissions (Zn, Pb, and V), wear debris (Cu, Cd, Fe, Ga, Mn, Mo, Sb, and Sn), and resuspended dust (Ca, Mg, K, and Rb), of airborne PM metals were categorized on the basis of the results of enrichment factor, correlation matrix, and principal component analysis. Size distributions of wear-originated metals resembled the pattern of crustal elements, which were predominated by super-micron particulates (PM1–10). By contrast, tailpipe exhaust elements such as Zn, Pb, and V were distributed mainly in submicron particles. By employing Cu as a tracer of wear abrasion, several inter-metal ratios, including Fe/Cu (14), Ba/Cu (1.05), Sb/Cu (0.16), Sn/Cu (0.10), and Ga/Cu (0.03), served as fingerprints for wear debris. Emission factor of PM10 mass was estimated to be 7.7 mg vkm−1. The metal emissions were mostly predominated in super-micron particles (PM1–10). Finally, factors that possibly affect particulate metal emissions inside Hsuehshan Tunnel are discussed.
