Tribochemistry & Surface Reactions

The chemistry of friction — friction-induced energy dissipation, mechanochemical bond activation, protective tribofilm formation, wear debris generation, and flash temperature spikes at sliding contacts.

Tribochemistry investigates chemical reactions triggered by mechanical forces at sliding or rolling interfaces. When two surfaces rub together, enormous pressures and transient temperature spikes crack molecular bonds, generate reactive radicals, and drive reactions impossible under equilibrium thermodynamics. This interplay of mechanics and chemistry governs everything from engine oil longevity to the wear of artificial joints.

These simulations let you explore friction-driven energy budgets, mechanochemical reaction kinetics, tribofilm growth dynamics, wear debris morphology, and flash temperature transients — all with real-time parameter control and physically grounded models drawn from tribology research.

simulator

Mechanochemical Reaction Kinetics

Simulate mechanochemical bond activation — explore how shear stress, temperature, and contact pressure lower reaction barriers and drive tribochemical transformations at sliding interfaces

simulator

Tribofilm Growth Dynamics

Simulate protective tribofilm formation — explore how contact pressure, temperature, additive concentration, and sliding cycles govern the nucleation and growth of tribochemical surface films

simulator

Wear Debris Generation & Morphology

Simulate wear particle formation — explore how load, hardness ratio, sliding distance, and wear mechanism govern the size, shape, and volume of debris ejected from tribological contacts
