In the present paper, formation of protective coatings on MA8 magnesium alloy by plasma electrolytic oxidation (PEO) with subsequent treatment fluoropolymer is considered. The morphology after accelerated climatic tests was investigated and elemental composition studied in a salt spray chamber (SSC). analysis obtained results demonstrated higher corrosion resistance fluoropolymer-containing lay...

Steel reinforcement corrosion in concrete structures such as bridges, industrial plants, marine structures, and coastal buildings is a growing concern due to its impact on cost, safety, serviceability. Corrosion leads spalling, cracking, reduced diameter, which can compromise structural integrity. This study examines the behavior of columns with corroded two phases. In first phase, 72 150 × mm ...

Abstract Corrosion probes designed based on an electrochemically integrated multi-electrode array have been evaluated in extensive field and laboratory evaluation program order to identify their capabilities visualizing probing critical forms of buried steel corrosion, particular, corrosion under disbonded coatings (CDC) stray current corrosion. Probes different designs were installed the pipel...

Steels are being designed with ever decreasing interstitial contents. At the same time, processing technology allows accelerated cooling without excessive distortion or microstructural gradients [1–5]. Lean steels with lower ‘carbon equivalents’ can therefore be manufactured, making fabrication relatively easy. Alloys such as these give uniform microstructures in spite of solidfication–induced ...

Alec Feinberg is senior principal reliability engineer at M/A-COM. He received his Ph.D. in Physics from Northeastern University. He has 17 years of reliability physics experience. He previously worked at TASC and AT&T Bell Laboratories. Dr. Feinberg has actively published in the area of reliability physics since 1986 and at the IEST on a wide variety of topics from accelerated reliability grow...

It has been studied the sensitivity of technique intermodulation ultrasonic waves to detect different damage states concrete due embedded steel corrosion. Accelerated corrosion tests have conducted on reinforced cement mortar specimens, while monitoring appearance and width evolution visible surface cracks performing measurements. established a statistically acceptable “upper control limit” for...

The study investigated the basic geomechanical and mineralogical evolution of the bentonite barrier under various experimental boundary conditions which replicated the near-field Thermo-Hydro-Chemico (THC) conditions in a repository. The relationships between the physicochemical alterations and changes in the geotechnical properties have seldom been studied, especially on a consistent dataset. ...
