Title of Contract, Award, or Gift: Mechanically Driven Growth of Hydrocarbons at Sliding Interfaces to Control Degradation and Wear

1.1.1 (SAM); Minimizing friction and wear-related mechanical failures across all length-scales remains a significant challenge in today’s moving mechanical systems framing the need for protecting the sliding components from load and shear generated damage propagation. The traditionally-used solution to friction and wear reduction requires deposition of a protective coating in an external processing chamber, which may be costly to perform and still does not provide long-lasting protection of the surfaces. The long-term goal of this project is to create a new conceptually-different approach to addressing the tribological problems in sliding surfaces by creating materials systems that are capable of self-replenishment through tribocatalytically-driven activation of the material synthesis. Toward this goal, this project focuses on understanding the friction- and wear-induced deformation of immersed in a hydrocarbon environment catalytic metal interfaces activating the in-situ synthesis of layered carbon films during sliding. By looking at platinum surfaces exposed to high load and shear stresses in presence of ethanol, the project will focus on three primary objectives: 1) Identify the tribocatalysis activation regimes and elucidate the material reconstruction and growth processes accompanying the tribocatalysis process; 2) Determine the consequences of tribocatalytically driven formation of the films on the response of dynamic system to applied mechanical stresses; 3) Define alternative solutions to tribocatalysis activation and quantify the corresponding changes in the response of materials to deformation.
