“…Figure 1. Shows the schematic representation of the twin-disc set up [9] In general, the transfer layer interpretations were done based on the post-mortem analysis through microscopy techniques (SEM or optical microscopy). However, using such methodology (post-mortem) to interpret the result does not provide the evolution and the mechanism undergone during the course of wear.…”

“…Since transfer layer is also process riven which differs from material to material and contact condition, the observed mechanisms in sliding does not represent the rolling condition. Even though research on polymer-metal rolling exists [8][9][10][11] the role of transfer layer and the evolution is not well described. Moreover, the role of transfer layer in modifying the tribological characteristics and the dynamicity involved in the transfer layer is unclear.…”

Polymer-metal pairs are found in many engineering applications, especially in rolling/sliding conditions. Transfer layer formation is imperative in friction and wear investigations on using these tribopairs. In the existing literature quantitative description was given for the formation of protective layer from the post mortem analysis (preferentially for sliding configurations). Since there is a dynamicity involved in the transfer layer the straight forward answer from the quantitative postmortem responses is rather uncertain. In the current research, rolling/sliding tests were performed for polymer and it's composite against metal to explore the underlying mechanisms using both qualitative and quantitative approaches.The tests were performed with intermediate pauses to observe the surface changes where characterization based on surface morphology and roughness (Ra) are used. The results show that the transfer layer deposition occurs in four stages which are explained from the view point of change in Surface roughness Ra in correspondence to its micrographs of the surface topography. The four stages can be categorized as 1. Scouring 2. Running-in 3. Transition and 4. Steady stage. Results show that in polymers the Ra increases during the scouring stage subsequently it decreases on reaching the steady stage. In steel counter parts the Ra does not change significantly during the scouring period. However, the Ra increases in the running-in period followed by a transition region leading to a steady state. Among the polymer and its composites the pure polymer shows significant change in roughness due to the difference in strength. The change in Ra for steel in the steady region also depends upon the contact materials, the mechanical and tribological properties of the polymer. Thus the stages can be used to study the transfer layer behaviour and understand the underlying mechanism in segregating the wear mechanisms both quantitatively and qualitatively.

“…Dix mesures par échantillon ont été réalisées sur une longueur de 15 mm avec un espacement entre chaque mesure de 0,5 mm. Ces essais nous ont permis de mesurer un taux d'usure à partir des points de rugosité et d'un système d'imagerie décrit par Sukumaran et al [33,34], Czifra et al [35] et Palásti-Kovács et al [36]. Figure 8 présente la variation du coefficient de frottement en fonction de la distance de contact parcourue pour chaque revêtement étudié.…”

“…D'autre part, le diborure de titane (TiB 2 ) peut être utilisé comme renfort pour les alliages autofondants à base de Ni, parce qu'ils présentent une dureté (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) GPa) et une température de fusion (3225°C) très élevées [7]. L'addition de TiB 2 aux revêtements de NiCrBSi doit donc améliorer leur résistance à l'usure.…”

L’influence de TiB2 dans des revêtements à base nickel est étudiée du point de vue microstructurale (identification des phases et mesure de la porosité), mécanique (dureté et module d’élasticité par indentation instrumentée) et du comportement mécanique (résistance au frottement par usure pion/disque). Dans les deux revêtements à 2,5 et 10 % de TiB2, on note la présence de siliciures, carbures et borures mais uniquement la présence d’oxyde de titane pour la teneur à 10 %. La porosité est plus élevée (6 %) lorsque la teneur en TiB2 est plus petite, elle est de 1,2 % pour l’autre revêtement. Après une discussion sur l’effet de taille et l’influence de la porosité sur la mesure des propriétés par indentation, la dureté est trouvée sensiblement la même dans les deux cas, autour de 3 GPa, alors que le module d’élasticité semble plus élevé (175 GPa au lieu de 150 GPa) pour la teneur la plus élevée en TiB2. Enfin, le coefficient de frottement est plus grand dans la zone de transition ou de rodage avant d’atteindre la même valeur moyenne de 0,6 dans le régime stationnaire.

In the initial stage of the abrasive wear process, the microtopography of steels drastically changes until it reaches a stable state. This stage can be described by the changes of the 3 dimensional roughness parameters. To predict these parameters, a simulation algorithm has been developed which was validated by wear tests. The applied load and the length of the wear path varied in wide interval during the experiments. The 1.1191 steel specimen was worn using an ISO 6344:1998 abrasive paper with a mesh size of 1200. It was found that both the experimental and the simulation results can be modelled in the same manner, meaning that we use a single function involving different parameters, which depends on the problem to be solved.
