Randomized trial examines how surface geometry affects friction between stainless steel and ice, indicating complex interactions.

This study investigates how different scales of surface geometry influence ice friction under varying conditions.
Conducted friction tests using a tribometer with controlled surface modifications.
Modified cross-section radius (7-16 mm), longitudinal radius (3-8 m), and surface roughness (Sa 0.02-0.17 µm).
Tested at cold (−10 °C) and warm (−2 °C) conditions with two applied loads (300, 600 N) and speeds (2, 4 m/s).
Macro-geometry changes decreased the coefficient of friction by up to 35% in cold and increased it by 20% in warm conditions.
Surface texture modifications had a lower effect, showing a load-dependent change of up to 15%.
Geometry modifications can lead to opposite trends in friction based on thermal conditions.

Jansons et al. (2026) studied this question.
