Austenitic stainless steel that is used in the industrial areas such as automotive has high physical and mechanical properties. In this study; thermophysical properties of 316L austenitic stainless steel prepared by powder metallurgy method that is attracted for researchers due to obtain net or near shaped product and complex shaped materials, have been investigated. Austenitic stainless steels pressed on the 400 and 600MPa pressures and pressed austenitic stainless steel samples sintered at 1200 °C temperature for an hour under inert gas atmosphere. The thermophysical features o these sintered austenitic stainless steel were performed at temperature ranging from RT to 600 °C via heat flux type Differential Scanning Calorimeter (DSC). These properties supported by SEM images, EDS spectrums and OM (Optic microscope) images.

“…1000 cm 3 of arti cial saliva was prepared in two batches in a 1000 ml measuring cylinder so as to have enough arti cial saliva for the experiment. This was done by adding 1000cm 3 of distilled water into the cylinder and adding 0.400 g each of potassium chloride (KCl) and sodium chloride (NaCl), 0.906 g of calcium chloride dihydrate (CaCl 2 .2H 2 O), 0.690 g of Sodium dihydrogen phosphate (NaH 2 PO 4 ), 1.000 g of Sodium supplied nanohydrate (Na 2 S.9H 2 O) and 1.00 g of Urea. The resulting mixture was stirred properly and used as arti cial saliva.…”

“…The drawback to the use of Titanium as a dental implant is its high cost [2]. Stainless steel, especially the 316L type are the most used metallic biomaterials used in biomedical applications due to their good biocompatibility, low price, excellent corrosion resistance, availability, easy processing and high strength [3,4]. These favourable properties and low cost has made 316L steel the most appealing biomaterial for dental implants, stents and orthopedic implants [3].…”

These favourable properties and low cost has made 316L steel the most appealing biomaterial for dental implants, stents and orthopedic implants [3]. The major disadvantage of use of steel as a biomaterial (dental implant) is the release of toxic metal ion due to some biological effects, which can be harmful to the body as they could lead to some undesirable reactions in the body tissues surrounding the implants [5][6][7].…”

ObjectivesThe aims of this study are to investigate the effect of concentration of citric acid in saliva environment on SS 316L and effect of ginger and garlic on SS 316L corrosion in citric acid-containing saliva environment.Methods.Seven SS 316L specimen of dimensions 1cm × 1cm were used for this study. The specimen were subjected to electrochemical corrosion test using an in artificial saliva containing citric acid with varying concentrations of 0.0 g/l, 3.0 g/l, 6.0 g/l, and 9.0 g/l electrochemical cell. 10 g/l each of garlic and ginger were also added to two of artificial saliva samples containing citric acid and one sample of artificial saliva contained 5 g/l of ginger and 5 g/l of garlic added together so as to study the corrosion effects of these substances on the SS 316L specimen in saliva environment. The results were displayed based on Tafel’s plot of current density against potential difference. Also, corrosion rates of the samples were determined and presented in graphical form.Results.The study results showed that citric acid is a good inhibitor of corrosion of SS 316L dental implant in oral environment with its inhibition efficiency depending on its concentration, and that the mechanism of this inhibition can attributed to the adsorption of citric acid onto the metal alloy (SS 316L) surface. The study also concluded that both ginger and garlic are promoters of corrosion of SS 316L alloy implants in saliva environment.

“…The corrosion resistance of the materials is an essential condition for the metals to be introduced into the human body, because the biocompatibility [1][2][3][4] of the metal-tissue must be guaranteed so as to avoid any deterioration of the tissue. Biocompatibility is described as the ability of a biomaterial to perform its desired function in relation to medical therapy, without causing undesirable local or systemic effects to the recipient [1][2][3][4]. Implantable medical devices are increasingly important in the practice of modern medicine.…”

Titanium alloys such as Ti6Al4V is the most used alloy used as implant for biomedical purposes. The conditions for a biomaterial to be selected for a particular application in the human body is that this should to conforms to the physical, chemical and biological characteristics, more precisely to be biocompatible, biofunctional and not ultimately sterilizable. Ti6Al4V alloy has mechanical properties suitable for many biomedical applications and has excellent corrosion resistance, which depends on the presence of a stable passive oxide film forming on its surface. Our study aims to evaluate the corrosion resistance of Ti6Al4V as a function in time with addition of 5 g/L and 10 g/L Lactic acid in biological solution Hank after exposure at 0 h (at immersion time), after 48 h (from immersion) and 168 h (from immersion). The evaluation of corrosion resistance of Ti6Al4V in Hank biological solution with addition of two concentration of Lactic acid it was done by electrochemical methods in terms of open circuit potential and polarization resistance (Rp). Lactic acid is used in this study because it is a component present in human blood in small quantities and is necessary for the metabolic processes used directly by the heart muscle, brain and nervous system. The increased lactic acid content in muscle appears as weight-bearing exercises. This is why it is important to know how the presence of lactic acid in larger quantities affects the implants. The study also highlights the importance of using longer testing times and more realistic solutions when testing biomedical materials.
