A multiphysics model based on the finite element method was adopted, emphasizing a deeper insight into rarely studied crevice corrosion behavior of stainless steel and titanium overlapping. The takes account damage due to inside crevice, different species transportation, local electrochemical reactions, homogeneous reactions in electrolyte, formation product its influence reaction. simulation r...

Corrosion morphology is a key factor that influences the reliability and service life of structure. As most structures under stress corrosion, there great need to understand effect on formation conditions different morphologies. This paper introduces numerical method simulate evolution surface The results indicate corroded will become rougher sharper with an increase in stress, as consequence, ...

All steels contain some amount of dissolved gases such as oxygen, hydrogen and nitrogen of which nitrogen is effective in improving the mechanical and corrosion properties of stainless steels if it remains in solid solution or precipitates as very fine and coherent nitrides or carbo-nitrides with iron or alloying elements. When nitrogen is added to austenitic steels it can simultaneously improv...

Nine uncemented hip prostheses of modular design were revised because of late infection (2 cases), femoral stem loosening or fracture (2), loosening of threaded cups (3) and protrusion of bipolar cups (2). At surgery we found tissue discoloration and macroscopic corrosion in four of the nine prostheses, located at the head-neck junction. Histological examination in most cases showed extensive n...

Modularity at the head-neck junction of the femoral component in THA became popular as a design feature with advantages of decreasing implant inventory and allowing adjustment of leg length, offset, and soft tissue balancing through different head options. The introduction of a new modular interface to femoral stems that were previously monoblock, or nonmodular, comes with the potential for cor...

Complex numerical models and simulations from the microscale to the macroscale have been developed for the corrosion of aluminium (Al) alloys typically used for aircraft construction, such as AA2024. The main motivation for developing the corrosion models and simulations is to make significant technical advancements in the fields of aircraft design (using current and new materials), surface pro...

The research progress surrounding second-phase particle-induced corrosion has been expounded through extensive work, including local (pitting corrosion, crevice stress corrosion) of Al2O3, (RE)-AlO3, CaS, MnS, NbC, and other particles in microalloyed high-strength rebars. By summarizing the mechanism these rebars, this review further explores fact that play an inducing role which guiding signif...
