The research aims to evaluate the impact of hBN nanoparticles on the lubricating properties and wear resistance of Al7075 alloy.
Investigated tribological behaviour under dry sliding and lubrication conditions
Used SAE 5W-30 engine oil with varying hBN concentrations (1, 5, 10 wt.%)
Conducted pin-on-disc experiments with normal loads from 10 to 50 N
Employed tactile sensors for 3D wear topography reconstruction
hBN nanoparticles enhanced lubrication, reducing wear loss from 622 mg (dry) to 44 mg (10 wt.% hBN)
Viscosity of lubricant increased by approximately 25% with hBN addition
Coefficient of friction decreased by about 90% with increased hBN concentration
Formation of tribo-layers reduced severe wear mechanisms and improved material durability
