Ammonia, produced by human and animal activities, contributes to water soil pollution because it is toxic for aquatic flora fauna, responsible eutrophication. In this work, the photoelectrocatalytic (PEC) oxidation of ammonia investigated employing a stainless-steel PEC reactor, consisting central UV Hg-vapor lamp surrounded metallic Ti mesh coated with photoactive TiO2 film, directly grown Pla...
چکیده پوشش نانوکریستال اکسید تیتانیوم (TiO2) با فرآیند اکسیداسیون پلاسمای الکترولیتی(Plasma Electrolytic Oxidation) تحت عملیات جریان ثابت در فرکانس-های 1000 و 1500 هرتز و سیکل کاری 10 و 15 درصد طی مدت زمان 10 دقیقه بر روی سطح تیتانیوم خالص تجاری (Commercially Pure ( CP ) Titanium) تشکیل شد. بررسی ساختار سطح و ترکیبات شیمیایی موجود در پوشش به وسیله میکروسکوپ الکترونی روبشی و پراش‌سنج اشعه ...
The enhancement of the biological properties of Ti by surface doping with hydroxyapatite (HA) is of great significance, especially for orthodontic applications. This study addressed the effects of HA particle size in the electrolyte suspension on the characteristics and biological properties of thin titania-based coatings produced on Ti-6Al-4V alloy by plasma electrolytic oxidation (PEO). Detai...
This research study describes recent advances in understanding the effects of addition organic acids, such as acetic, lactic, citric and phytic on process plasma electrolytic oxidation (PEO) Ti using an alkaline bath. As developed over workpiece is central to determine particular morphological structural features growing oxide, focus then inter-relationships between electrolyte resultant regime...
The biodegradable metals, including magnesium (Mg), are a convenient alternative to permanent metals but fast uncontrolled corrosion limited wide clinical application. Formation of barrier coating on Mg alloys could be successful strategy for the production stable external layer that prevents corrosion. Our research was aimed develop an oxide using plasma electrolytic oxidation (PEO) in silicat...
