Atmospheric corrosion is one of the major sources hydrogen in a high-strength-steel product service. Even low concentrations absorbed can cause embrittlement-related material degradation. The extent atmospheric and thus related entry highly dependent on environmental parameters, such as relative humidity. present work focused at humidity, where rates are expected to be low. Hydrogen insertion d...

The equilibrium solubility data of CO2 in the various aqueous blends of triisopropanolamine (TIPA) + monoethanolamine (MEA) with the total alkanolamine concentration of 2 mole / dm3 were measured at the temperatures of 30, 40, 50, 60 and 70 oC and CO2 partial pressures below 100 kPa. The experiments were done in an atmospheric gas absorption syste...

This paper studies the corrosion behavior of B10 copper-nickel alloy in marine environment. Accelerated degradation test under marine environmental conditions was designed and performed based on the accelerated testing principle and the corrosion degradation mechanism. With the prolongation of marine corrosion time, the thickness of Cu₂O film increased gradually. Its corrosion product was Cu₂(O...

A new approach is proposed to numerically predict and study atmospheric corrosion for ranging droplet size distributions the influence of geometry. The methodology allows a prediction based on observed contact angles. mechanistic finite element model, including oxygen transport Butler-Volmer kinetics, solved in order obtain current density as function This done range both radii computed densiti...

To protect copper artefacts of the cultural heritage from atmospheric degradation protective treatment must be applied. Two types treatments: microcrystalline wax (Cosmolloïd wax) and decanoate solution (HC10) were tested. aspects considered: penetration treatments in corrosion layers, its durability. Equivalent efficiencies for both demonstrated. The seems to depend essentially on application ...

Machine learning methods were applied to data with an atmospheric corrosion monitoring sensor based on strain measurements improve the evaluation accuracy of thickness reduction a low-carbon steel plate due corrosion. Monitoring used in this study taken previous using active–dummy gauges for product experiments. Values measured by before inducing via saltwater treatment test piece and reference...
