The factors that influence magnesium (Mg) corrosion in vitro are systematically evaluated from a review of the relevant literature. We analysed the influence of the following factors on Mg biocorrosion in vitro: (i) inorganic ions, including both anions and cations, (ii) organic components such as proteins, amino acids and vitamins, and (iii) experimental parameters such as temperature, pH, buffer system and flow rate. Considerations and recommendations towards a standardised approach to in vitro biocorrosion testing are given. Several potential simulated body fluids are recommended. Implementing a standardised approach to experimental parameters has the potential to significantly reduce variability between in vitro biocorrosion tests, and to help build towards a methodology that accurately and consistently mimics in vivo corrosion. However, there are also knowledge gaps with regard to how best to characterise the in vivo environment and corrosion mechanism. The assumption that blood plasma is the correct bodily fluid upon which to base in vitro methodologies is examined, and factors that influence the corrosion mechanism in vivo, such as specimen encapsulation, bear consideration for further studies.

“…A reliable prediction model for the ingress of chlorides into concrete should consider the complex combination of several transport processes (Neville 1995;Kropp et al 1995) that include diffusion, capillary sorption (i.e. absorption of water containing chlorides into unsaturated concrete), and permeation (i.e.…”

“…Despite its simplicity and extensive use, this model has some shortcomings, because: (i) the diffusion coefficient is not a constant but rather depends on time, temperature, and depth because of the heterogeneous nature and aging of concrete (Cady and Weyers 1982;Neville 1995;Kropp et al 1995); and (ii) the top surface of the bridge deck is subjected to a continually changing chloride exposure. In general, the values of the surface chloride concentration and diffusion coefficient can be estimated from Eq.…”

“…The apparent chloride diffusion coefficient is determined by fitting the solution of Fick's second law of diffusion to measured chloride profiles expressed in terms of total chloride concentrations (including both free and bound chlorides). Since only the chlorides dissolved in the pore solution (free chlorides) are responsible for the initiation of the corrosion process (Tuutti 1982;Neville 1995;Kropp et al 1995), this procedure yields only the value of the so-called apparent diffusion coefficient because chloride binding is not taken into account. The probabilistic distribution of chloride concentration at a given depth and exposure time is generated using Monte Carlo simulation.…”
