Abstract

Bu çalışmada, altlık olarak Ti6Al4V malzemesi kullanıldı ve yüzeyi ZrO2-ağ.%22 MgO tozları kullanılarak plazma sprey yöntemi ile kaplandı. Yüzey kaplama yapılırken akım değerleri 500 A, 600 A, 700 A olacak şekilde üç farklı sprey mesafesinde ( 100 mm, 150 mm, 200 mm) gerçekleştirildi. Kaplanmış numuneler daha 600 ⁰C sıcaklıkta 2 saat süreyle sinterleme işlemine tabi tutuldu. Elde edilen yüzey tabakalarının karakterizasyonu SEM, EDS, Optik Mikroskop, XRD ile yapıldı. Aşınma deneyleri 1000 m kayma mesafesinde, 10 N yükte ve 122.5 mm/sn kayma hızında gerçekleştirildi. ZrO2-ağ.%22 MgO tozlarıyla kaplanan ve sinter-lenen Ti6Al4V altlık malzeme yüzeyinde kaplanan tabakalarda ZrO2 ve MgO tespit edildi.

Coating of Titanium and Its Alloy with ZrO2-MgO using Plasma Spraying Method and Investigation of Coating Properties

Abstract

In this study, Ti6Al4V material was used as a substrate and its surface was coated by plasma spray method using ZrO2-22 wt% MgO powders. The surface coating was carried out at three different spray distances (100 mm, 150 mm, 200 mm) with current values of 500 A, 600 A, and 700 A. The coated samples were then subjected to sintering at 600 ⁰C for 2 hours. Characterization of the obtained surface layers was performed by SEM, EDS, Optical Microscope, and XRD. Wear tests were carried out at a sliding distance of 1000 m, a load of 10 N, and a sliding speed of 122.5 mm/s. ZrO2 and MgO were detected in the coated layers on the surface of the Ti6Al4V substrate coated and sintered with ZrO2-22 wt% MgO powders.
