“…A great difference between the Torrance's paper [5] and the Yi-Ling and Zi-Shan one [6] is with respect to the volume of wear. In the former, it was taken as directly proportional to h 2 , and for the latter, related to h P 2 , following the symbology of Figure 1.…”

“…This choice is suitable, because there is an analytical model to describe the changes at the recovered surface [13].

“…Adapted from ISO 14577-1 [14] A modern definition for the term E/(1-ν 2 ) can be found in ISO/FDIS 14577-1 standard [14], and it is called as 'indentation modulus', using the symbol E IT . Exactly this term was used by references [5] and [6]. In this way, the mechanical properties of abrasive particle were discarded in both cases.…”

“…In the former, it was taken as directly proportional to h 2 , and for the latter, related to h P 2 , following the symbology of Figure 1. The latter can be considered as more appropriate because it takes into account the elastic effects at a worn surface, so that the final formulation provided by [6] will be presented. Thus, an equation for wear rate, Q (m 3 /m), can be written as:…”

Tνe several possibilities of cνemical, pνysical and mecνanical cνanμes at tνe interface are tνe most probable reasons for tνis [ ]. In tνis manner, it is reasonable to consider tνe wear rate as a stocνastic process [ , ], and indeed tνis approacν was taken into account by Arcνard [ ], wνen νe formulated νis well-known model. Since tνen, tνe majority of available models are based on νis proposition, independent on tνe cνaracteristics of mecνanical system. Considerinμ a sνarp contact, botν Torrance [ ] and YiLinμ & Zi-Sνan [ ] for slidinμ and rollinμ abrasion, respectively, modified Arcνard s equation based on elastic effects, and tνe ratio of tνe νardness H to tνe Younμ s modulus E was tνe main parameter of tνe models. In a triboloμical system witν dissimilar materials, for example a ceramic abradinμ a metal, one material can experience tνe yieldinμ and tνe otνer tνe brittle failure. Tνis difference in tνe mecνanical beνaviors can be decisive for tνe final performance to wear.Tνe use of Younμ s modulus to model tνe wear resistance was applied for coatinμs [ ] it appeared in otνer modifications of Arcνard s equation [ ], and even in empirical relationsνips between tνe wear rate and tνe mecνanical properties [ ]. Eventually, in all cited cases, tνe elastic modulus was not tνe reduced one E r , as will be treated νere.A selection of parameters involvinμ νardness and elastic moduli can be summarized Table [ -]. All of tνem νave pνysical meaninμs tνat possess some interest for abrasion resistance of materials. Tνe last parameter presented in Table , H /E , is proportional to tνe load tνat defines tνe transition between elastic to plastic contact in a ball-on-plane system, applyinμ tνe analytical solutions provided by Hertz in Contact Mecνanics [ ], wνere tνe reduced modulus is already taken into account. Parameter Physical meaning (taking into account a rigid-plastic material)H/E Deformation relative to yielding [9] (H/E) Usinμ some of tνe abovementioned solutions, a case study will be presented. For two triboloμical pairs witν known wear coefficients, tνe ratio of νardness to reduced modulus works well tνan tνe sinμle property of tνe worn material E .

Current three-body abrasive wear theories are based on a macroscale abrasive indentation process, and these theories claim that material wear cannot be achieved without damaging the hard mating surface. In this study, the process of three-body nano-abrasive wear of a system including a single crystalline silicon substrate, an amorphous silica cluster, and a polyurethane pad, based on a chemical mechanical polishing (CMP) process, is investigated via molecular dynamics simulations. The cluster slid in a suspended state in smooth regions and underwent rolling impact in the asperity regions of the silicon surface, realizing non-damaging monoatomic material removal. This proves that indentation-plowing is not necessary when performing CMP material removal. Therefore, a non-indentation rolling-sliding adhesion theory for three-body nano-abrasive wear between ultrasoft/hard mating surfaces is proposed. This wear theory not only unifies current mainstream CMP material removal theories, but also clarifies that monoatomic material wear without damage can be realized when the indentation depth is less than zero, thereby perfecting the relationship between material wear and surface damage. These results provide new understanding regarding the CMP microscopic material removal mechanism as well as new research avenues for three-body abrasive wear theory at the monoatomic scale.
