Effect of Dipping Number on Morphology of Ta2O5 Coatings Made by Sol-Gel Method on AZ91 Mg Alloy

نویسندگان

چکیده

Yap?lan çal??ma, sol-jel yöntemi kullan?larak üretilen Ta2O5 kapl? AZ91 Magnezyum (Mg) ala??mlar?n?n karakterizasyonuna yöneliktir. Mg ala??mlar? hafiflikleri ve insan kemi?inin mekanik özelliklerine yak?n özellikleri nedeni ile ortopedik uygulamalarda kullan?m aç?s?ndan ciddi bir potansiyele sahiptir. Fakat korozyon dayan?mlar? vücut içinde uzun süreli kullan?mlar için yetersiz kalmaktad?r. Tantal (Ta) ise yüzeyinde olu?an oksit tabakas? sayesinde dayan?m? çok yüksek olan toksik etki yaratmayan elementtir. çal??mada toz metalurji üzerine farkl? dald?rma say?lar?nda kaplanmas? say?lar?ndaki bu de?i?imin kaplamalar?n morfolojisine etkisinin incelenmesi amaçlanm??t?r. Numuneler kapland?ktan sonra morfolojilerindeki de?i?im elektron mikroskobu (SEM-EDS) X-???n? k?r?n?m? (XRD) incelenmi?tir. Çal??man?n sonucunda yönteminde kar??la??lan çatlakl? yap?larda, adac?klar aras? mesafelerin k?sald??? gözlemlenmi?tir. Artan say?s? ortalama 1, 3 7 µm kal?nl?klarda kaplama tabakas?na sahip numuneler üretilmi? yüzeyde daha homojen yap?s? olu?umu sa?lanm??t?r.

Effect of coating time on the corrosion behavior of ceramic coatings containing hydroxyapatite nanoparticles by plasma electrolytic oxidation method on AZ31 Mg alloy in simulated body fluid

In this study, the effect of coating time on the microstructure and corrosion behavior of AZ31 Mg alloy coated by plasma electrolytic oxidation (PEO) method has been investigated. For this purpose, phosphate-based electrolyte containing hydroxyapatite nanoparticles was used at different times of 5, 10 and 15 minutes. The surface properties and chemical composition of the coatings were investiga...
