Self-Organization during Friction of Slide Bearing Antifriction Materials

This article discusses the peculiarities of self-organization behavior and formation of dissipative structures during friction of antifriction alloys for slide bearings against a steel counterbody. It shows that during self-organization, the moment of friction in a tribosystem may be decreasing with the load growth and in the bifurcations of the coefficient of friction with respect to load. Sel...

Dissolution of composition B detonation residuals.

Composition B (Comp B) detonation residuals pose environmental concern to the U.S. Army because hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), a constituent, has contaminated groundwater near training ranges. To mimic their dissolution on surface soils, we dripped water at 0.51 ml/h onto individual Comp B particles (0.1-2.0 mg) collected from the detonation of 81-mm mortars. Analyses of the eff...

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 ...
