“…In many applications, such as bearings and engine blocks [4], aluminium alloys may be subject to tribological conditions leading to wear. In this case it is essential to increase the wear resistance by using appropriate alloying and heat treatments [1,[5][6][7] or by introducing reinforcing hard phases such as Si [3,8] and/or SiC [7,9,10]. When a contact operates in a corrosive environment its deterioration can be significantly affected by surface chemical phenomena.…”

“…Results from the literature indicate the occurrence of wear-corrosion interactions in the tribocorrosion of aluminium alloys. H. Mindivan et al [6] studied the wear behaviour of 7039 Al alloy (Al-Zn alloy) under dry (reciprocating wear tests using 1.5N as normal applied load and a 10mm diameter Al 2 O 3 ball as counterbody) and in corrosive wear (same tribological conditions as used in dry tests plus a 3 g/l NCL + 10 ml/l HCl solution) conditions. The authors compared two heat-treated alloys: a T6 (age-hardened) alloy and a RRA ("retrogression and re-aging") treated alloy.…”

Mechanical and electrochemical deterioration mechanisms in the tribocorrosion of Al alloys in NaCl and in NaNO3 solutions

Tribocorrosion of Al-Si-Cu-Mg alloys was investigated in 0.05 M NaCl and 0.1 M NaNO3 solutions under severe sliding and controlled electrochemical conditions. A simple galvanic coupling model was developed to analyze and quantitatively predict the evolution potential of the open circuit potential during tribocorrosion. According to this model and the obtained results, galvanic coupling was established in the NaNO3 solution within the wear track between passive and mechanically depassivated areas. In the NaCl solution, galvanic coupling was established between the whole depassivated wear track and the surrounding area. This difference was attributed to different mechanical properties of the passive surfaces.

“…Some authors report that tribocorrosion of Al alloys in NaCl based solutions is characterized by adhesive wear, abrasive wear and plastic deformation [15][16][17]. In the case of passive aluminum, one would expect a significant increase in corrosion rate due to the mechanical removal of the passive film and the exposure of bare metal to the solution.…”

Valuable insights into the wear-corrosion behavior of metals, as well as into the tribocorrosion field through the development of simulation models of tribocorrosion experiments, can contribute in rationalizing wearaccelerated experiments and their open circuit potential (OCP) behavior under rubbing. These results demonstrate that mathematical models of controlled tribo-electrochemical contacts can complement the physical experiment and add valuable understanding to the tribological behavior of metals, alloys, and generally to materials in an electrochemically active environment. The excellent agreement of experimental wear data and the experimental OCP curves with the OCP simulations with time establishes the concepts underlying the galvanic coupling model as a valid methodological approach toward a quantitative description and mechanistic understanding of the tribo-electrochemical experiment. Besides analyzing stellite tribocorrosion, application of the model to Al alloy data has helped us quantify the relative contributions of chemical and mechanical wear and reveal the underlying synergy. Ti metal tribocorrosion under variable load has revealed that the contact pressure P av , can reach much lower values within the experimental time domain and finally be the cause of interruption of the initial wear mechanism.

Copper chemical mechanical polishing (CMP) in barrier layer slurries with periodate as oxidant has not been intensively studied. This work presents an investigation into copper tribocorrosion in potassium periodatebased slurries during CMP. The research focused on copper tribocorrosion behavior, the surface chemical and electrochemical reaction products, and the electrochemical mechanism during CMP. The copper surface film was characterized by Raman spectra experiments. Tribocorrosion tests combined with CMP chemical experiments were conducted to study the tribochemical behavior and wearaccelerated corrosion effect. The results show that copper corrosion is more severe in acid solutions than in alkaline conditions. The copper surface is mainly passivated with copper oxides, copper hydroxide, and copper iodide. Small amounts of copper iodate, copper periodate, and iodine could be detected under specific pH conditions. Abrasion could help to get a uniform passivation film on copper surface consisting of copper oxides, copper hydroxide, and copper iodide only. The material loss due to wear-accelerated corrosion during CMP was also investigated. The results show that under weakly alkaline conditions (pH 9 and pH 10), the wear-corrosion effect plays an important role in the total material loss due to corrosion. The wearaccelerated corrosion is mainly caused by the exposure of more cathodic reaction sites to the slurry for participation in the redox reaction and the local galvanic corrosion during the CMP process. The high wear corrosion proportion of the total corrosion (DI c /I cc ) could help to obtain a better surface quality and desirable material removal rate during CMP.
