In one well-known example — a circus poster — only close inspection reveals that a tightrope walker at the center of the composition wears prison garb.
There was also a white earth of Eretria, and the annularian white, creta anularia or anulare, made from the glass composition worn in the rings of the poor.
Effects of particle concentration on phase composition and wear behaviour were investigated.
The morphology, structure, composition, microhardness, wear resistance, electrochemical properties, and wetting characteristics are investigated systematically.
The morphology, structure, composition, microhardness, wear resistance, electron chemical corrosion, and wetting properties against solder are investigated.
The relationship between physical properties, coatings compositions and wear mechanisms during machining Inconel 718 is discussed.
The coating microstructures and elemental compositions inside wear tracks, as well as the wear products, were examined by scanning electron microscopy, energy-dispersive spectroscopy, and Raman spectroscopy.
The paper presents the results of a laboratory study, aimed at verifying the possibility to use two particular typologies of electric arc furnace (EAF) steel slags, in substitution of the natural aggregates, in the composition of wearing course asphalt concrete for flexible pavements.
The concept that opsonization may differentially regulate uptake of different compositions of wear debris is also supported by observations that the spectra of adherent human serum proteins demonstrate a level of particle specificity [ 33].
Past studies with 10 μm PEEK and PTFE powders resulted in composite solid lubricant that (at the optimal composition) had a wear rate of k = 2 × 10−9 mm3/Nm with a friction coefficient of μ = 0.12.
