“…To recognize these effects, numerous investigations were undertaken. Corrosion resistance of metals and alloys in AS, in the presence of fluoride has been investigated [1,10,11,12,14,19,24] The presence of fluoride ions (added as NaF) drastically affects the corrosion behavior of Ti metal, Ti-6Al-7Nb, and Ti-6Al-4V alloys and constituent metals in AS as confirmed by electrochemical methods [1]. All the titanium alloys in fluoridated acidified saliva show an active behavior due to the presence of major concentrations of HF and HF2− species that dissolve the spontaneous air-formed oxide film giving rise to surface activation [13].…”

Dental erosion is the chemical dissolution of the tooth structure. Factors like eating disorders and gastrointestinal diseases are recognized as intrinsic factors for dental erosion. To regulate the growth of teeth, people are implanted with orthodontic wires made of different materials. These are exposed to the influence of oral environment, food intake, toothpastes, and mouthwashes. During this process, the materials may undergo corrosion. Hence, various researchers have made a study on the influence of artificial saliva (AS) on the corrosion behavior of these alloys. The excellent corrosion resistance to the oral environment of dental alloys is important for biocompatibility as well as for orthodontic employment permanence. Various types of metal alloys are being used for the orthodontic treatment, which undergo chemical or electrochemical reaction with the oral environment. The oral environment is highly belligerent under several situations and leads to corrosion. This article reviews the effects of fluoride concentration, the pH value and protein content in AS and the composition of the metal alloys on the corrosion resistance of orthodontic appliances using electrochemical methods and surface characterization techniques such as scanning electron microscopy inductively coupled plasma-optical emission spectroscopy (ICP-OES) and X-ray photoelectron microscopy.

In this study, Mg-Ca-Zn-Co alloy specimens for biomedical applications were produced by the powder metallurgy method. The Mg-Ca-Zn-Co alloy could be used as a scaffold material in tissue engineering applications. Electrochemical corrosion behavior of the specimens was investigated in simulated body fluid environment. Electrochemical corrosion resistance of the specimens was increased with increasing Zn and Ca contents of the alloy up to an optimum composition and then decreased. Optimum values for Ca and Zn additions were about 0.7 wt.% and 3.0 wt.% respectively. Young's modulus values of the specimens were determined by nondestructive ultrasonic measurement. Alloying element addition increased the Young's modulus of the specimens. Precipitation hardening of the Mg-Ca-Zn-Co alloy increased the Young's modulus and the corrosion rate of the specimens.

Solid foams are a very important class of lightweight materials with energy absorption properties for application in automotive and aerospace industry. In such applications, foams are subjected not only to uniaxial but in most cases to very complex multiaxial stress states. Hence, yield surfaces are needed for the reliable prediction of the failure behavior by simulations under multiaxial loading. As multiaxial loading of cellular solids is a very challenging task, in literature, yield surfaces are usually based mainly on simulation results not validated by real experimental data sets. The present contribution starts with a review of the theory of yield surfaces and numerical models. It gives a deep insight into the state of the art on the experimental assessment of yield surfaces for solid foams. Finally, a yield surface and its post‐yield surfaces are determined exemplarily for open‐cell aluminum foams by using a multitude of experimental methods.
