چکیده

Titanium alloys are used in different industries such as biomedical, aerospace, aeronautic, chemical, and naval. Those have high requirements with few damage tolerances. The aim of this work was to study the corrosion behavior titanium anodizing non-anodizing alkaline (KOH NaOH) solutions, exposed 3.5%wt. NaCl 3.5% wt. H 2 SO 4 solutions at room temperature using cyclic potentiodynamic polarization (CPP) according standards obtain electrochemical parameters passivation range (PR), type, passive layer persistence, potential (Ecorr), rate. alloy Ti Beta-C anodized presented better resistance than Ti-6Al-4V both media. smallest rate is samples (4.72 E-8 A/cm ) highest CP2 (1.61 E-5

Nanoporous Titanium Oxide Morphologies Produced by Anodizing of Titanium

A quick and dependable technique has been developed that allows us to selectively produce anodized TiO2 in the form of nanotubes. The process employs mild chemical conditions and ambient temperature. The method can consistently produce nearly 100% surface coverage of nanotubes within 10 min of anodizing. Anodizing in relatively high pH electrolytes for 1 hour permitted us to produce nanotubes o...

Corrosion Performance of Stainless Steel and Nickel Alloys in Aqueous Sodium Hydroxide as Revealed from Cyclic Voltammetry and Potentiodynamic Anodic Polarization

The electrochemical behavior of nickel, Inconel 600, Incoloy 800 and 316 stainless steel electrodes in different concentration of NaOH solution was investigated using the cyclic voltammetry technique (CV). All the curves in the anodic branch of the CV are characterized by anodic dissolution peak (A), passive region (B), anodic dissolution peak (C) before oxygen evolution. In the case of the cat...

Titanium Alloys

Although originally discovered in the 18th century [1], the titanium industry did not experience any significant advancement until the middle of the 20th century through the development of the gas turbine engine [2]. Since then, the aerospace sector has dominated worldwide titanium use with applications in both engines and airframe structures [3]. The highly desirable combination of properties,...
