New Scuffing Test Methods for the Determination of the Scuffing Resistance of Coated Gears
, 2013 In modern machines the problems of the prevention of scuffing of the gear teeth is still very important. One of the reasons is that for many years the technique development is related to increasing the loading of the friction surfaces accompanied by decreasing their size [1].

Evaluation of Roughening Mar Resistance of Glossy Ductile Thermoplastics
Journal of Applied Polymer Science, Volume 142, Issue 32, August 20, 2025.ABSTRACT Mar is a type of subtle surface damage caused by sliding objects, visible to the human eye, and critically impacts the esthetics of polymeric surfaces. Despite its critical importance, no standardized method exists for quantifying roughening mar resistance.
