Work Package 1:
Fabrication and
functionalisation of the essential tribocolloid and tribo-meso-structure
components of the SLCN.
The main goal of WP1 is to create and enhance these components, essential for achieving superlubricity in contact networks. The work package comprises six tasks dedicated to providing structured and functionalized surfaces and nanoparticles, ensuring successful realization of the objectives.- Task 1.1: Meso-structured and functionalized counter-surfaces
- Task 1.2: Production of penciling 2D
functionalization
- Task 1.3: CVD and thermal conversion 2D-material
functionalization
- Task 1.4: Tribocolloid synthesis
- Task 1.5: Surface functionalized spherical metal
oxide particles
- Task 1.6: 2D graphene-like nanosheets
Work Package 2: Pre/post surface
characterization. The main objectives of this work package is
characterization of superlubricious surface structure and composition before
and after tribological testing.
- Task 2.1:
Surfaces
pre-test characterization
- Task 2.2:
Surfaces
post-test characterization
- Task 2.3: Characterization of surface functionalized and
carbon coated oxide particles and 2D nanosheets.
Work Package 3:
Superlubricious micro-contact. The main objective of WP3 is to characterize and model the operation of individual superlubricious micro-contacts, which will later form the elements of the Superlubricious Contact Network (SLCN). The outcomes of this WP are crucial for the SSLiP program as they will guide the results in WP4, where the complete contact network operation is investigated.
- Task 3.1:
Performance
of superlubricious components under high pressure
- Task 3.2:
Understanding
degradation vs. regeneration of superlubricity
- Task 3.3:
Microscopic
understanding of the rejuvenation process
Work Package 4:
Superlubricious
contact network.
WP4 aims to investigate the Superlubricious Contact Network (SLCN) by combining advanced visualization and network-level modeling. This work package tests various geometries and parameters to identify mechanisms that enable superlubricity survival. During the initial reporting period, WP4 focused on conducting experiments and multi-contact simulations of SLCN, along with parameter studies using granular simulations. Additionally, theoretical work assisted in designing different types of patterning.
- Task 4.1:
Visualization of
tribocolloid structure under sliding
- Task 4.2: Visualization
of superlubricious contact network (SLCN) operation
- Task 4.3:
Characterisation of the SLCN
- Task 4.4: collective behaviour
of superlubric granular particles in simulation
- Task 4.5:
Simulations of sliding
with patterned superlubric surfaces without third bodies
