Ag-Au bimetalik alaşımlı ince filmlerin mikro-X ışını flüoresans sistemi ile homojenliğinin belirlenmesi

Bu araştırmanın amacı, farklı Ag-Au oranlarının Ag-Au bimetal alaşımlarının homojenliği üzerindeki etkisini araştırmaktır. Gümüş (Ag) -altın (Au) bimetal alaşımlı ince filmler, Vaksis Termal Evaporatör sistemi ve farklı altın (Au) katkı oranlarında kuvars kristal mikro terazi dedektörü kullanılarak üretildi. Microbeam X-Ray flüoresans spektrometre sistemi, bimetalik Au-Ag alaşımlı ince filmlerin homojenliğini hesaplamak ve farklı konsantrasyon değerleri ile üretim Au-Ag oranlarını hesaplamak için kullanıldı. Hesaplanan oranlar ile üretim değerinin uyumlu olduğu görülmektedir.

Determination of the homogeneity of the Ag-Au bimetallic alloy thin films by means of a micro beam X-Ray fluorescence setup with using elemental composition

The goal of this work is to research the effect of different Au-Ag ratios on the homogeneity of Au-Ag bimetal alloys. Thin films of silver (Ag)-gold (Au) bimetal alloy were produced using Vaksis Thermal Evaporator system and quartz crystal microbalance detector at different gold (Au) additive ratios. Micro beam X-Ray fluorescence spectrometer system was used to calculate the homogeneity of bimetallic Ag-Au alloy thin films and to calculate production Au-Ag ratios with different concentration values. It is seen that the calculated ratios and production value are in good agreement.
