The results of laboratory and development wear tests of Al-based composite materials reinforced with TiC or SiC particles under dry sliding friction conditions are presented. It is shown that composite materials reinforced with TiC have better tribotechnical properties (friction coefficient, wear rate, wear coefficient, stability coefficient) as well as wear resistance. On the basis of the friction surface and wear debris investigations, the mechanisms of wear of the composite materials are determined.

A method for production of Sn–Sb–Cu alloy (babbitt) based composite coatings reinforced with micron-sized SiC and B4C particles on a steel substrate has been developed. A combined action of...

The wear products and the friction surfaces of the composite materials fabricated by reactive casting after the addition of commercial-purity aluminum AD1, titanium and nickel powders, and nanosized modifiers to a matrix melt are studied. The dispersity and the chemical composition of the wear products that form an intermediate layer between the contacting surfaces are analyzed, and the dominating wear mechanisms under experimental tribological loading conditions are determined. It is shown that the formation of such a disperse intermediate layer during lubricant-free friction of the synthesized composite materials decreases the temperature in the tribological contact and ensures a transition from weak to intense wear at higher critical loads.

The results of studying aluminum-matrix composite materials (CMs) reinforced ex situ by disperse nanosize powders obtained by plasma-chemical synthesis, as well as by intermetallic phases formed by in situ reactions, are presented. The structure and tribological properties of aluminum-matrix CMs have been examined. The effect that the manufacturing modes, nature, and size of reinforcing particles have on the structure, wear resistance, coefficient of friction, and stability factors has been discussed.
