“…To do so, the first step is to get the chemical composition of the layer as a function of the depth. Different XPS studies were investigated [13,15,37,38] and from these measurements, it can be concluded that the different conditions do not affect the iron concentration versus depth profile significantly. For this study, the profiles originating from [38] are used, see Fig.…”

“…Because of the fact that the environmental regulations are becoming more restrictive concerning phosphorous and sulphur containing additives [6], the usage of ZDDP is restricted more and more. This results in the fact that a lot of research is currently done in understanding the mechanism behind the excellent antiwear properties of this additive [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] to eventually produce a more environment-friendly additive with the same excellent wear protection like ZDDP. These studies give a good overview of the film formed by this specific additive package; however, up to now, only little of this information is indeed used to model mild wear present in systems lubricated using a lubricant containing ZDDP.…”

In this paper, a wear model is introduced for the mild wear present in boundary-lubricated systems protected by additive-rich lubricants. The model is based on the hypothesis that the mild wear is mainly originating from the removal of the sacrificial layer formed by a chemical reaction between the base material and the additive packages present in the lubricant. By removing a part of this layer, the chemical balance of the system is disturbed and the system will try to restore the balance for which it uses base material. In this study, mechanical properties reported throughout literature are included into the wear model based on observed phenomena for this type of systems. The model is validated by model experiments and the results are in very good agreement, suggesting that the model is able to simulate wear having a predictive nature rather than on empirical-based relationships as Archard's linear wear model. Also a proposal is made to include the transition from mild to severe wear into the model creating a complete wear map.

“…Since zinc dialkyldithiophosphates (ZDDPs) are widely used in engine oils, primarily as anti-wear additives, many researchers have studied their anti-wear and anti-seizure performance under reciprocating pure sliding conditions which simulate piston ring and cylinder liner assembly. In previous research, friction machines such as the Optimol SRV and Cameron Print reciprocating rig have been employed and tribofilms formed on the specimens after rubbing tests have been investigated [3][4][5][6][7][8][9]. Recently, a new approach to monitor ZDDP film formation process under pure sliding conditions using AFM (atomic force microscopy) was introduced by Gosvami et al [10].…”

The anti-wear and anti-seizure performance and action mechanisms of zinc dithiophosphate (ZDDP) have been investigated under reciprocating pure sliding conditions to simulate piston ring and cylinder liner assembly, using new techniques. The Mini Traction Machine-Space Layer Imaging is a useful method for monitoring tribofilm formation by ZDDPs. However, tests are generally carried out in mixed sliding-rolling conditions and ZDDP film formation in reciprocating pure sliding conditions is rarely investigated. In this paper, the authors describe an investigation of ZDDP film formation in stationary ball on reciprocating disc pure sliding conditions and compare the results to those obtained in unidirectional pure sliding conditions. In unidirectional pure sliding conditions, the worn area on the ball expands with test time. By contrast, in reciprocating pure sliding conditions, tribofilm forms on the stationary ball and no significant damage occurs. In the initial tribofilm formation under reciprocating pure sliding conditions, solid particulate tribofilm with a high concentration of S forms initially in the contact area and subsequently breaks up. During further rubbing, a Zn-and P-rich tribofilm forms on the comminuted sulphur-rich tribofilm and also the area where the initial tribofilm was removed.

“…In fact, many instrumental techniques of material characterization and surface analysis have been used in tribofilm characterisation, as shown in Table 1. Readers interested in this issue can read more in literatures [11,[12][13][14][15][16] .…”
