Time-Dependent Contact Behaviour of ZDDP-Derived Tribofilms: A Viscoelastic Layered Model Approach
Summary
Researchers studied how protective lubricant films (called tribofilms) formed by the common engine oil additive ZDDP behave under pressure over time, finding that these films act like a layered viscoelastic material — with mechanical properties that change depending on load duration — which matters for predicting how well engine components resist wear.

Researchers proposed a multifactorial criterion-based approach to optimising lubricant formulations for friction units operating under extreme conditions, incorporating rheological properties and chemical composition to sustain micro-elastohydrodynamic lubrication and reduce wear. The framework integrates viscosity class selection, plasticity assessment, and lubrication mode criteria to prevent lubrication layer breakdown and extend component service life.
