A facile and cost-effective practical approach to develop clinical applications of NiTi: Fenton oxidation process

ABSTRACT

To date, numerous attempts have been made to modify the surface condition of NiTi shape memory alloy to fully benefit from its desirable characteristics, and develop its potential clinical applications. In this survey, the Fenton oxidation process as a newly presented technique for surface modification of NiTi, was employed to address two major priorities in biomedical applications of NiTi, i.e. corrosion improvement and suppression of Ni ion release. To meet these priorities, two important variables involved in the Fenton oxidation process, namely immersion time and electrolyte temperature, were controlled. Results suggested that the application of such an oxidation process may considerably improve the corrosion behaviour of NiTi. The Fenton oxidation process carried out at 65°C for 24?h yields the lowest corrosion current density, 74% lower than bare NiTi. Additionally, Ni ion releases from the surface of NiTi after Fenton's oxidation decreases by ～97%.     

Concrete cover cracking owing to reinforcement corrosion – theoretical considerations and practical experience

Reinforcement corrosion might lead to cracking and spalling of the concrete cover owing to the volume expansion associated with the deposition of some of the possible corrosion products. This is not only aesthetically unpleasing, it might also accelerate deterioration processes or become a safety issue for passing traffic. The present paper discusses first the mechanisms of carbonation‐ and chloride‐induced reinforcement corrosion and considers the chemistry of aqueous iron in order to identify the type of corrosion products as well as their location of formation. Furthermore, practical examples are summarised in order to compare the documented behaviour of a number of real structures with the theoretical considerations made. It is shown that for the case of purely chloride‐induced (pitting) corrosion, precipitation of corrosion products is strongly delayed or may even not occur. Implications are discussed with respect to time‐to‐corrosion prediction models and visual inspection of reinforced concrete structures. Both the theoretical considerations and the practical experience illustrate that relying on outwardly visible signs to detect internally on‐going corrosion must be done with caution if localised reinforcement corrosion cannot be excluded.

SKPFM investigations of intermetallic compounds of innovative Er‐ and Zr‐containing Al–Si–Mg alloys and their influence on corrosion localization in saline solution

The paper aims at characterizing the influence of intermetallic compounds on the corrosion localization of innovative Al–Si–Mg Er‐ and Zr‐containing casting alloys. Samples of the investigated materials were studied by means of optical and scanning electron microscope micrographs, immersion tests, and scanning Kelvin probe force microscope (SKPFM) analyses in the T6 temper. Combination of immersion tests and SKPFM analyses allowed to identify those classes of intermetallic compounds promoting localization of the corrosion process. It was found that intermetallic compounds richer in Fe were the most critical for corrosion localization; furthermore, additions of Er caused a marked decrease of the potential difference of intermetallic compounds with respect to the Al matrix and a consequent less intense microgalvanic coupling, which translates into slower corrosion kinetics. Further, Zr additions slightly increased the potential difference of intermetallic compounds with the Al matrix, promoting a faster corrosion process.
