Study and Computational Simulation of Nanomaterial Coating to Reduce Crevice Corrosion
The crevice correction is a common type of localized corrosion which costs multibillion dollar losses in many different fields including aerospace, automobile, and building structures. The crevice geometry can easily catch moisture and impurity which accelerates the chemical corrosion. It is one of the dangerous corrosions that can cause sudden failure of the products and involve the human inju...
متن کاملCombining Rigorously Controlled Crevice Geometry and Computational Modeling for Study of Crevice Corrosion Scaling Factors
Microfabrication methods have been used to construct crevice formers of rigorously controlled gap and length. These have been used to study the IR-controlled crevice corrosion of Ni200 in 0.5 M H2SO4 to determine the effect of crevice gap ~G! on the position of the accelerated attack (xcrit) within the crevice. The experimental results were then compared to the results of computational studies....
متن کاملStudy and Computational Modeling of Nano Coating to Protect Products from Atmospheric Corrosion
The atmospheric corrosion rate of materials changes based on different environmental conditions including time to be exposed to wet condition, relative humidity, surrounding temperature, and impurity of the air. The adhesive bond is relatively weak in conventional surface coating process which may lead the separation of these coatings and reduction of effective coating lifecycle. Some conventio...
متن کاملCombining the Ohmic Drop and Critical Crevice Solution Approaches to Rationalize Intermediate Attack in Crevice Corrosion
Crevice corrosion material loss is often most severe at intermediate distances into the crevice. This intermediate attack can be rationalized using the ohmic drop model of Pickering if and only if the material in question exhibits active/passive behavior in the crevice environment. Conventional theories that ascribe control of crevice corrosion to chemical changes exclusively cannot rationalize...
