Inhibitive Performance of Carboxymethyl Cellulose and Additives on Corrosion of Carbon Steel in Acidic and Alkaline EnvironmentsJournal of Bio- and Tribo-Corrosion - Tập 4 - Trang 1-12 - 2018
S. C. Nwanonenyi, H. C. Obasi, A. M. Chidiebere
The potential of the mixture of carboxymethyl cellulose (CMC) and additives (PVP, PAA and PVAc, respectively) as an eco-friendly corrosion inhibitor for carbon steel in 1 M HCl and 1 M KOH solutions, respectively, was studied using gravimetric and potentiodynamic polarization measurements and quantum chemical calculations. Gravimetric results revealed that CMC inhibited the corrosion of carbon ste...... hiện toàn bộ
Chemical Composition and Green Anticorrosive Potential of Thymus broussonnetii Boiss subsp. broussonnetii Essential Oils in Hydrochloric Acid MediumJournal of Bio- and Tribo-Corrosion - Tập 5 - Trang 1-10 - 2018

The chemical composition of the essential oils of Thymus broussonnetii Boiss subsp. broussonnetii was carried out using GC/MS. The essential oils were characterized by carvacrol (39.51%) as the main constituent. The other components were benzene, 1-methyl-2-(1-methylethyl) (14.80%), gamma-terpinene (10.32%), alpha-pinene (9.7%), thymol (7.9%), and 3-cyclohexen-1-ol, 4-methyl-1-(1-methylethyl) (3.2...... hiện toàn bộ
On the Interaction Between Erosion and Corrosion in Chromium Carbide CoatingJournal of Bio- and Tribo-Corrosion - Tập 4 - Trang 1-11 - 2018
A. R. Hemmati, S. M. Soltanieh, S. M. Masoudpanah
In this paper, the effects of slurry flow velocity and impact angle on erosion–corrosion (E–C) behavior of the chromium carbide coating in NaCl solution containing SiO2 particle were investigated. A jet impingement system was used. The mass loss test, polarization curve and surface characterization were employed to examine the coating performance. The erosion–corrosion regime of the Cr7C3-coated a...... hiện toàn bộ
Fretting-Corrosion Apparatus with Low Magnitude Micro-motion (≤ 5 µm) for Hip Implant Taper Junctions: Development and Preliminary OutcomeJournal of Bio- and Tribo-Corrosion - - 2024

Fretting-corrosion is one of the failure processes in many applications, including biomedical implants. For example, the modern design of hip implants with multiple components offers better flexibility and inventory storage. However, it will trigger the fretting at the implant interfaces with a small displacement amplitude (≤ 5 µm) and usually in a partial slip region. Although many studies have b...... hiện toàn bộ
Role of Thermal Spray Coatings on Erosion, Corrosion, and Oxidation in Various Applications: A ReviewJournal of Bio- and Tribo-Corrosion - Tập 10 - Trang 1-17 - 2024
S. Suresh Kumar, C. Durga Prasad, Harish Hanumanthappa
Depending on the location, extreme environmental conditions must have different graded properties. This is especially important for surfaces that are exposed to mechanical, chemical, thermal, and electrochemical interactions, as these can harm other components in use, such as gas turbines, ball valves, aerospace, power plants, and heat exchangers. The primary problems, such as oxidation, corrosion...... hiện toàn bộ
