... that are influenced by friction, lubrication, and wear. Equations for calculating lubricant film thickness, which determines whether the gears operate in the boundary, elastohydrodynamic, or full-film lubrication range, are given. Also, given is an equation for Blok's flash temperature, which is used for predicting...

... bound on abrasive wear resistance is modeled by the following equation, known as the inverse rule of mixtures (IROM), where overall wear behavior is assumed to be a function of the individual contribution from each phase. Wear resistance ( W −1 ) (as modeled by Khruschov) ( Ref 14 ) is: (Eq 1...

... ). Estimation of Tool Wear A study by Meng ( Ref 16.9 ) showed that there are more than 300 equations to predict tool wear, each of which is a correlation of several parameters and is derived from various wear tests. Among these, the Archard wear equation (Eq) is commonly used for modeling tool wear...

... to hardness, as predicted by some wear equations. Hardfacings were not tested in these studies, but composite hardfacings can compete with cemented carbides, which have abrasion characteristics similar to the VC and TiC coatings in the silica abrasion studies. Thus, a 60 HRC steel may have a wear volume of 2...
