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

In the present study, CeO2 nanoparticles modified with stearic acid (mCeO2) were synthesized using the magnetic stirrer and subsequently vacuum dried for 12 h (MN12) and 24 h (MN24). Three different weight percent concentrations (0.1%, 0.3%, and 0.5%) of each MN12 and MN24 nanoparticle are added to the base lubricating oil (SAE15W40). The physicochemical properties of the synthesized nano-lubrican...... hiện toàn bộ
Synthesis, Characterization, Anti-corrosive/Anti-tumor Applications of a New Type Arylazo Compound 1,7-Bis(2-Hydroxy Phenyl)-4-(Phenyl Hydrazono)-Hepta-1,6-Diene-3,5-DioneJournal of Bio- and Tribo-Corrosion - Tập 4 - Trang 1-13 - 2018

The purpose of the study is to synthesize and characterize a new arylazo compound 1,7-bis(2-hydroxyphenyl)-4-(phenylhydrazono)hepta-1,6-diene-3,5-dione (HPHDD) . The corrosion inhibition behavior of the compound on mild steel in 1 M HCl was investigated using weight loss method, electrochemical impedance spectroscopy, and potentiodynamic measurements. The results revealed that this arylazo compoun...... hiện toàn bộ
Microbially Influenced Corrosion and its Control Measures: A Critical ReviewJournal of Bio- and Tribo-Corrosion - Tập 9 - Trang 1-13 - 2023
Padmalatha Rao, Lavanya Mulky
Corrosion of materials, induced either by chemicals, or environmental factors or microbials is always a threat to industries. If remain unattended, it will have direct influence on environmental pollution. In recent years lot of work is reported on microbially influenced corrosion which is more prevalent in biotechnology and chemical engineering process industries. However, reports for preventive ...... hiện toàn bộ
Effect of Milling on the Hardness and Wear Behaviour of Cast Al6061 Reinforced with Al2O3 NanoparticlesJournal of Bio- and Tribo-Corrosion - Tập 8 - Trang 1-11 - 2021

Alumina nanoparticles is generated through planetary ball milling of powder mix compraise of aluminium (Al) and manganese dioxide (MnO2). The powder mix of Al and MnO2 is considered in the weight proportion of 1:2.416 and milled for 120, 240 and 360 min. In the milling jar, the powder mix will experience impact force while collusion with ball-powder-ball and ball-powder-wall of the jar. These impa...... hiện toàn bộ
Evolution of 307 L Stainless Steel Corrosion on the Oxidative Stability of Biodiesel During StorageJournal of Bio- and Tribo-Corrosion - Tập 7 - Trang 1-13 - 2021

The present work aims to examine the link between biodiesel degradation and the corrosion behavior of the 307 L stainless steel used for its storage. Biodiesel was produced from soybean waste cooking oil (SWCO) by trans-esterification process based on a heterogeneous catalyst and methanol. 307 L stainless steel was used to assess the metal surface corrosion after direct contact with the biofuel.
