Friction and Wear of Self-Lubricating Materials for Hydropower Applications under Different Lubricating Conditions

Self-lubricating bearings in hydropower applications are often lubricated with water under boundary lubricating conditions. Polyhydric alcohols replacing water have shown the potential to reduce both friction and wear. The objective of this work is, therefore, to evaluate the effect of a polyhydric alcohol-based environmentally-acceptable lubricant (EAL) on the friction and wear of self-lubrica...

EFFECT OF AGING CONDITION ON STRUCTURE AND THE PROPERTIES OF Al-ALLOY / SiC COMPOSITE

The heat treatments have been designed to vary the matrix microstructure in P/M processed SiC reinforced 7xxx Aluminum alloys to determine the effects of matrix microstructure, interface behavior on the mechanical properties. Smooth tensile, notched bend tests were performed. The results conclude that the clustered regions have been observed as preferred initiation sites in both tensile and not...

CrN–Ag self-lubricating hard coatings

CrN–Ag composite films, 2.5–4 Am thick, were deposited by reactive magnetron sputtering on Si and stainless steel substrates in a 0.4 Pa pure nitrogen atmosphere at 500 -C. The layer composition was controlled by the relative power to 7.5-cm-diameter Ag and Cr targets to be 0, 3, 12, and 22 at.% Ag. The layers exhibit a dense columnar microstructure where the Ag is homogeneously distributed in ...
