Influence of surface layer on mechanical and corrosion properties of nickel-titanium orthodontic wires.
OBJECTIVE To analyze the effect of various coating formulations on the mechanical and corrosion properties of nickel-titanium (NiTi) orthodontic wires. MATERIALS AND METHODS Uncoated, rhodium-coated, and nitrified NiTi wires were observed with a three-point-bend test, surface roughness (Ra) measurement, scanning electron microscopy, energy dispersive spectroscopy, and electrochemical testing ...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Martensite Strain Memory in the Shape Memory Alloy Nickel-Titanium Under Mechanical Cycling
This paper describes an experimental study of stress-induced martensitic phase transformation in the SMA Nickel-Titanium. The rich local thermo-mechanical interactions that underlie transformation are examined using three-dimensional Digital Image Correlation (strain fields) and infrared imaging (thermal fields). We quantify the complex local interactions between released/absorbed latent heat a...
متن کاملInfluence of Fluoride and Stress on the Electrochemical Properties of Nickel-Titanium Coils
INFLUENCE OF FLUORIDE AND STRESS ON THE ELECTROCHEMICAL PROPERTIES OF NICKEL-TITANIUM COILS Ashley Barnes Marquette University, 2015 The aim of this study was to examine the effects of fluoride and stress on the electrochemical properties of nickel-titanium coils. Forty Dentsply GAC NiTi coils were divided into four groups of ten and individually tested. Twenty coils were placed in a solution o...
متن کاملInfluence of the nickel-titanium alloy components on biological functions
Background Nickel-titanium alloy is applied to biomaterials such dental wire, stents and so on, because they have outstanding capacities for corrosion-resistant, adequate mechanical strength and shape-memory [1,2]. On the other hand they have a risk of metal allergy because of leaking nickel ions from them in aqueous conditions. It is not clear the reason why nickel causes allergy and what the ...
