A new approach to ceramic lubrication: tribopolymerization
… or often ineffective. Therefore, the concept of tribopolymerization -- originally proposed by Furey and later modified by Furey and Kajdas -- is used as a new approach to boundary lubrication of ceramics. In this approach, potential polymer-forming compounds are used in minor concentrations in a …

A study of tribopolymerization under fretting conditions
… has been conducted to determine whether or not tribopolymerization can occur under conditions of fretting contact. Using a laboratory test consisting of oscillating hard steel balls loaded against flat steel or aluminum disks, effects of various monomers on friction, wear, and surface film …

First Principles Study Of Tribopolymerization On Conductive Material Surfaces
… and metal sillisides (PtxSi). We found that the tribopolymerization mechanism lies on to surface catalytic effect enhanced by local confined stress, and a general trend follows for those materials as we investigated is: (i) chemisorption; (ii) dehydrogenation; (iii) polymerization. In particular, …

Tribopolymerization as an approach to two-stroke engine lubrication
… of an air-cooled, two-stroke, gasoline engine by tribopolymerization is presented. Tribopolymerization is defined as the planned or intentional formation of protective polymeric films directly and continuously on rubbing surfaces to reduce damage and wear by the use of minor concentrations of …

Tribopolymerization: ceramic lubrication under high loads and high speeds
An experimental study of ceramic lubrication by tribopolymerization at high loads and high speeds is presented. One condensation monomer -- C₃₆ dimer acid/ethylene glycol monoester -- and five addition monomers, i.e., diallyl phthalate, lauryl methacrylate, vinyl acetate, …

Tribopolymerization: Anti-Wear Behavior of New High Temperature Additive Classes
… focuses on a boundary lubrication method termed tribopolymerization -- the formation of polymers at the tribological interphase. The research evaluated new high-temperature classes of anti-wear additives. The work involved experiments on steel and alumina material pairs with a pin-on-disk …

Ceramic lubrication: vapor phase tribopolymerization and a new high speed, high load pin-on-disk machine
… of ceramic lubrication through the concept of tribopolymerization from the vapor phase is presented. Four vinyl monomer additives were studied, i.e., vinyl acetate, diallyl phthalate, lauryl methacrylate, and vinyl octadecyl ether. The liquid additives were heated, vaporized, and delivered to …

Triboemission From Ceramics: Charge Intensity and Energy Distribution Characterizations
… and controlled. In particular, the mechanism of tribopolymerization for some addition-type monomers is thought to be initiated and controlled by triboemitted low-energy electrons. This Ph.D. dissertation presents the experimental work carried out at the Virginia Polytechnic Institute and State …

Pretreatment of Small Four-Stroke Engine Components for No-Oil Hot Tests
… i.e., monomers, which were used in previous tribopolymerization studies. Tribopolymerization is defined as the planned or intentional formation of protective polymeric films directly and continuously on rubbing surfaces to reduce damage and wear by the use of minor concentrations of selected …
