This paper contains a review of the most vital concepts regarding the analysis and design of film systems. Various techniques have been presented to analyse and predict the failure of films for all common types of failure: fracture, delamination, general yield, cathodic blistering, erosive and corrosive wear in both organic and inorganic films. Interfacial fracture or delamination is the loss of bonding strength of film from substrate, and is normally analysed based on the fracture mechanics concepts of bi-material systems. Therefore, keeping the focus of this review on bonding strength, the emphasis will be on the interfacial cracking of films and the corresponding stresses responsible for driving the delamination process. The bi-material characteristics of film systems make the nature of interfacial cracks as mixed mode, with cracks exhibiting various complex patterns such as telephone cord blisters. Such interfacial fracture phenomenon has been widely studied by using fracture mechanics based applicable analysis to model and predict the fracture strength of interface in film systems. The incorporation of interfacial fracture mechanics concepts with the thermodynamics/diffusion concepts further leads to the development of corrosive degradation theories of film systems such as cathodic blistering. This review presents the suggestions for improvements in existing analysis techniques to overcome some of the limitations in film failure modelling. This comprehensive review will help researchers, scientists, and academics to understand, develop and improve the existing models and methods of film-substrate systems.

“…Significant effort has been undertaken into developing a greater understanding of the abrasion-corrosion wear properties of stainless steels and for a range of different applications [4][5][6][7][8][9][10][11]. Stainless steels are known to have the ability to form a protective passive film on their surface when exposed to a corrosive media.…”

“…However, when such exposure is combined with some form of mechanical action (such as abrasion or sliding motion), the passive oxide film can be locally or evenly destroyed. Garcia et al, adopting a ball-on-disc (stainless steel disc against an alumina ball) test method, have studied the passivation of S31603 in the presence of a 0.5 M H 2 SO 4 solution [5]. A passive range was observed which could be divided into three regions based on the applied load.…”

“…However, between 2 and 12 N, removal of passive oxide film on S31603 sample resulted from of periodic delamination of the oxide. Above 12 N, a relationship between the thickness of the passive oxide film and wear rate could not be established because both film and the bulk material were worn simultaneously [5]. Lee and Shih [11] studied the abrasive corrosive wear of plasma-nitrided alloy steels of type UNS S30400, UNS S41000 and UNS G41400 in a tribotest in which the specimen was held under potentiostatic control at anodic and cathodic potentials in 3% sodium chloride (NaCl) solution (pH 6.8).…”

In this study, the synergistic effects of abrasion and corrosion on UNS S30403, S31603 and S32760 stainless steels have been investigated using a micro-abrasion test rig. The stainless steel samples have been studied under both pure abrasion (PA) and abrasion-corrosion (AC) conditions simulated by using silicon carbide based slurries in either distilled water or 3.5% sodium chloride solutions. Tests have been conducted at various abrasive concentrations (0.006-0.238 g/cm 3 ) and at 38 and 180 m sliding distance to enable the interactions between abrasion and corrosion to be better understood. Wear mode identification and regime mapping was used to establish the dominant wear mechanism at the different slurry concentrations. The synergistic effect has been quantified and related to the material composition and the grooving or rolling abrasive wear mechanisms present. The synergistic levels were typically positive and have been discussed in terms of their dependence on the integrity of the passive films and the repassivation kinetics. The three-body abrasion-corrosion rates for all steels were found to be 14 times higher than two-body abrasion-corrosion rates. S30403 shows weak repassivation performance with electrochemical activity being proportional to mechanical activity. S31603 showed a constant electrochemical activity over a variety of mechanical conditions, indicating a stronger repassivation performance than S30403. S32760 has the best repassivation performance with negative synergistic characteristics until abrasion rate are such that depassivation occurs and the electrochemical activity is then comparable to the other steels.

“…While close attention has been paid to tribocorrosion testing and measurements related to a sliding contact (two-body abrasion), much less is understood about viability of tribo-electrochemical methods for testing three-body abrasion corrosion [6][7][8]. In sliding tribocorrosion a typical two-body contact involves an inert ball or pin rubbing against a metallic wear sample (working electrode) with reciprocating or unidirectional motion [3][4][5]9]. In this configuration, the ratio of wornto-unworn surface area is often low, and during the 'out-ofcontact' or 'non-friction' time the worn area of passive alloys repassivates, at least partially [10].…”

High-Cr white cast irons (WCIs) are multiphase alloys commonly used in aqueous industrial environments in applications that require both high abrasion and high corrosion resistance. Various electrochemical techniques can be useful in elucidating tribocorrosion characteristics of metallic materials undergoing wear in a corrosive environment. This study is focused on the interpretation of electrochemical measurements applied to three-body abrasion corrosion contacts of high-Cr WCIs. Particular attention has been paid to determine whether tribo-electrochemical data can pick up any effects that the multiphase microstructure of WCIs may have on the tribocorrosion characteristics, especially in environments containing chloride ions. Since both wear and corrosion of multiphase alloys are usually not uniform, their tribocorrosion behaviour is difficult to study and is still poorly understood. The experimental results are discussed in terms of benefits and limitations of tribo-electrochemical techniques such as polarization (potentiostatic, potentiodynamic) and electrochemical noise (galvanic coupling, potentiostatic) in studying abrasion corrosion behaviour of high-Cr WCIs. The application of high-resolution surface analysis techniques (microprobe, NanoSIMS, C-AFM and SKPFM), used in support of the electrochemical data interpretation, is also demonstrated.
