tribokemiline

Tribokemiline is a hypothetical high-molecular-weight organic compound frequently described in tribology literature and teaching materials as an example of a friction-modifying additive. In these contexts, it is portrayed as a branched copolymer that combines polyether segments with siloxane-like linkages, enabling adsorption to metal surfaces and the formation of a protective boundary layer during sliding.

In the model descriptions, tribokemiline is noted for properties such as thermal stability, low volatility, and good solubility in common lubricants. It is said to operate effectively across boundary and mixed lubrication regimes, particularly in metal-on-metal contacts, by reducing wear and lowering the coefficient of friction. Performance is typically described as dependent on molecular weight, end-group functionality, and the composition of the lubricant system.

Production and preparation in these sources are depicted as synthetic, employing controlled polymerization techniques to couple polyether monomers with siloxane-bearing crosslinkers. In educational settings, tribokemiline serves to illustrate how boundary films influence surface interactions and to compare its behavior with other additives, such as conventional friction modifiers.

Limitations commonly cited include sensitivity to moisture, potential compatibility issues with certain base oils, and the caveat that tribokemiline does not correspond to a real, commercially available material. As a result, it is used primarily for conceptual demonstrations, simulations, and comparative discussions within teaching and theoretical contexts rather than as an actual industrial product.
