Method & Evidence

AimTo characterize the physical, chemical, mechanical, and thermal properties of a tribofilm material based on activated carbon, nanochitosan, and silicone oil, and to evaluate its self-healing capabilities for metal surface coatings.

MethodExperimental characterization and performance testing

ProcedureActivated carbon was synthesized from palm shells, and nanochitosan was derived from shrimp shells. These were then combined with silicone oil using the sol-gel method in varying compositions (40%-60% activated carbon). The resulting film-forming solutions were characterized for physical properties (density, viscosity, surface tension). Coatings were applied to aluminum and copper, and their surface roughness, friction coefficient, wear rate, thermal conductivity, and corrosion resistance were evaluated. Self-healing properties were tested on carbon steel in a saline environment.
