... are linear with respect to the quantities in the denominator, notably sliding distance or time of contact. In fact, several types of wear, like sliding wear and solid particle erosive wear, do not experience linear wear rates throughout their histories. For example, running in (wear in) can occur in...

... rather than total wear. Wear does not occur in a linear fashion. Published wear rates for composites are 12 to 79 μm/year in contact-free areas and 39 to 135 μm/year in occlusal contact areas ( Ref 85 ). For autocured ( Ref 143 ) and ultraviolet light-polymerized ( Ref 144 , 145 ) composites, wear has...

.... For alloys, n is calculated by linear mixing, as shown in the example A 0.3 B 0.7 : n = 0.3 × 2 + 0.7 × 3 = 2.7, where 2 and 3 are the numbers of valence electrons in A and B, respectively. Note that this method can be used, in principle, to analyze the wear-corrosion synergy and determine the...

It is therefore tempting to extrapolate such data to higher load situations, especially because simple wear models generally predict a linear load dependence. However, this is not a...
