Effects of sliding velocity on the coefficients of friction in a model orthodontic system.


Four arch wire alloy products were evaluated against 400- or 600-grit finished stainless steel contact flats at 34 degrees C under prevailing atmospheric conditions. Six relative velocities (10, 1.0, 0.1, 5 x 10(-2), 5 x 10(-3), and 5 x 10(-4) mm/min) were evaluated as many as three times each in order to simulate a range of sliding motion which approaches… (More)
