“…A design method for minimizing wear for reciprocating sliding contacts is the engineering model for wear developed by Bayer (the zero wear model) [25,26], where the maximum contact shear stress τ max is given as a function of the number of cycles n and the shearing yield stress of the material τ y by [24] …”

a b s t r a c tThe reciprocating sliding wear behavior of high-silicon bainitic steels has been studied on microstructures obtained from two alloys containing 0.3 and 1.0 wt% C, which were isothermally transformed between 200 and 425°C. Results show an order of magnitude improvement in the wear resistance of the nano-scaled bainitic structures with respect to the ultra-fine with similar hardness values. The scale of the microstructure and the level of retained austenite determine the wear mechanism and eventually, the wear rate.

“…To explore the assumption of a common wear mechanism, a series of wear experiments was performed using the modified Bowden-Leben apparatus [1,2,4], which provides an oscillatory motion with a controlled amplitude. Three series of tests were performed on a particular contact configuration using the same material and the same load for each.…”

The "IBM wear model," which has previously been used to describe the wear of electrical contacts as a result of gross sliding motion, is used to describe contact wear in the case of small-amplitude sliding motion. This model was applied to a particular contact configuration on which a series of wear tests was performed. The empiricalresults of the tests are compared to the theoretical expressions and good agreement is found, thus indicatingthat the wear mechanism is essentially the same for both large-and small-amplitude slidingcontact. TheoryThe model used to describe the wear of electrical contacts under gross sliding conditions is known in technical literature as the "IBM wear model" [4][5][6][7]. In this model the wear in a sliding system is governed by one or the other of the following equations:where Q is the maximum cross-sectional area of the wear scar taken in a plane perpendicular to the sliding direction;T max is the maximum shear stress produced during sliding; W is the length of the apparent contact area taken in the direction of sliding; C is a constant dependent for a given system on the materials and lubricants used; and N is a measure of the amount of sliding. Specifically, N is the number of passes of sliding, where a pass is a distance of sliding equal to W.In this formulation of the wear process, the nature of the predominant wear mechanism determines which equation is to be applied to a given system. For a wear process in which the energy going into wear remains constant as wear progresses, Eq. (1) is the appropriate equation. Equation (2) applies to a system in which the

“…The ANSYS Multiphysics technique was used to analyze the thermal behavior of the dry contact between the brake pad discs during the braking process and the rotor's critical temperature by taking into account other parameters such as the material used, geometric configuration of the disk and the braking mode [32]. Many analytical and mathematical models that explain wear processes in different types of friction joints having different materials; under different operating conditions have yet come into being [33][34][35][36]. Archard was the first author proposed a linear wear model for metals [37].…”

Automotive disc brake pads are subjected to different wear situations under variable operating conditions; industry needs to evolve the methodology to estimate wear rate of brake pads to address the issue of extreme brake fading. In the present investigation friction and wear behavior of different brake pads is tested on newly developed test rig under dry sliding conditions. The analytical model is proposed to simulate different operating conditions using Winkler differential and integral relation. The infrared thermal images at the interface of the brake pad and disc were obtained to analyze the temperature variations under different operating conditions. The results showed the correlation of the load (20 N-80 N) and speed (300 rpm-1100 rpm) with temperature at the interface between pad and disc varies from 97.80 C to 306.70 C, which is moderate rise. The coefficient of friction increases as load increases from 0.24 at 300 rpm, 20 N load and maximum value 0.64 at 1000 rpm, 60 N load. Temperature rise at higher load and speed having the major influence on changing the friction and wear behavior of pad friction material. There is a consistency between reported experimental observations and obtained values from the proposed the analytical model.
