Metallic materials in practical use are normally exposed to corrosion in the atmospheric and aqueous environments. Metallic corrosion is one of the problems we have often encountered in our industrialized society; hence it has been studied comprehensively since the industrial revolution in the late eighteenth century. Modern corrosion science was set off in the early twentieth century with the ...

A mini-flowloop was developed to study CO2 corrosion and corrosion/erosion interactions, and to assess the effectiveness of inhibitors under conditions that simulate multi-phase pipelines. The miniflowloop was used to study the effect of testing time, steel chemistry, velocity, temperature, fluid chemistry, sand and inhibitors on corrosion rates. The measured corrosion rates in inhibited and un...

Although nitinol is one of most popular materials of intravascular stents, there are still few confirmative biocompatibility data available, especially in vascular smooth muscle cells. In this report, the nitinol wires were corroded in Dulbecco's modified Eagle's medium with constant electrochemical breakdown voltage and the supernatant and precipitates of corrosion products were prepared as cu...

Surface characteristics such as roughness and contact angle of flat and nanostructured titanium samples and diamond-like carbon films (DLC) electrodeposited on the nanostructured samples were evaluated. Also, the mechanical properties and the corrosion resistance of the samples were evaluated in phosphate buffered saline (PBS). Biocompatibility was assessed by analyzing an in vitro cell culture...

Human osteoblastic alveolar bone cells were cultured for 28 days in control conditions and in the presence of three non-lethal concentrations of AISI 316L stainless steel (SS) corrosion products. Cells were exposed to SS corrosion products in two experimental situations: (i) in selected stages of the incubation time (during the first, second, third and fourth week of culture); and (ii) during t...

hen the first trivalent chromium electroplating process was commercially introduced in the mid-l970s, information on the corrosion properties of the deposits and other physical properties was unknown. To obtain a comprehensive understanding about the corrosion properties of trivalent chromium electrodeposits over a variety of nickel deposits, chromium deposits from trivalent chromium electrolyt...

this paper aims at finding the long term coupled effect of high temperature and constant high relative humidity on the corrosion rehabilitated patches of chloride contaminated steel reinforced concrete. this paper is an extension of previous research in which the authors experimentally corroborated re-corrosion in the repaired reinforced concrete (rc) patches in the form of macro-cells. in prev...

The early validation of a 20 year service integrity for the bonded interfaces in low cost solar arrays is an important requirement in the Low Cost So 1 ar Array ( LSA) project. An atmospheric corrosion model has been developed and verified by five months of corrosion rate and cl fmatology data acquired at Mead, Nebraska LSA test site. Atmospheric corrosion monitors (ACMs) installed at the Mead ...

Microbially induced corrosion (MIC) is a complex problem that affects various industries. Several techniques have been developed to monitor corrosion and elucidate corrosion mechanisms, including microbiological processes that induce metal deterioration. We used zero resistance ammetry (ZRA) in a split chamber configuration to evaluate the effects of the facultatively anaerobic Fe(III) reducing...

Effective protection of power sources from corrosion is critical in the development of abiotic fuel cells, biofuel cells, hybrid cells and biobateries for implantable bioelectronics. Corrosion of these bioelectronic devices result in device inability to generate bioelectricity. In this paper Al/Au/ZnO was considered as a possible anodic substrate for the development of a hybrid cell. The protec...
