Abstract

Amaç: Bu çalışma, seçici lazer ergitme (SLE) yönteminde kullanılan Co-Cr alaşım tozlarının metal-seramik (MS) bağlantı dayanımı üzerine alaşım tipinin etkisini değerlendirmeyi amaçlamıştır.
Gereç ve Yöntem: Otuz adet bar şekilli Co-Cr metal altyapı, çekirdek metal(n=10, Grup-D) kullanarak döküm yöntemi ile, tip 4 (n=10, Grup-T4) ve tip 5 (n=10, Grup-T5) alaşım tozu kullanarak SLE yöntemi ile üretildi. Çekirdek metal ve alaşım tozlarının mikro yapısı X-ışını diffraksiyon (XRD) yöntemi ile incelendi. Tüm metal altyapıların merkezine feldspatik porselen uygulandı ve fırınlandı. Tüm numunelerin MS bağlantı dayanımı(MPa) 3 nokta bükülme testi ile ölçüldü. MS bağlantı dayanımı verileri, tek yönlü varyans analizi ve Tamhane T2 post hoc testi (α=0.05) kullanılarak analiz edilmiştir. Her gruptan iki numunenin kırık metal-seramik arayüzü enerji dağılımlı X-ışını spektroskopisi ve stereo mikroskop kullanılarak incelendi.
Bulgular: Grup-T5 (25.62 ±2.02) Grup-D (37.28 ± 4.46; P=0.000016) ve grup T4’den (32.82 ± 2.85; P=0.00019) anlamlı derecede daha düşük MS bağlantı dayanımı göstermiştir. Bükme testi sonrasında metal ara yüzeyindeki porselen kalıntısının miktarı en fazla Grup D'de, en az Grup-T5’de olduğu doğrulandı.
Sonuç: Bu çalışmanın bulguları alaşım tipinin, SLE kullanılarak üretilen altyapıların MS bağlantı dayanımını etkileyebileceğini göstermiştir.

The Effect of Alloy Type on Metal-Ceramic Bond Strength of Co-Cr Frameworks Fabricated by Selective Laser melting.

Abstract

Aim:This study aimed to evaluate the effect of alloy type on the metal-ceramic(MC) bond strength of Co-Cr alloy powders used in the selective laser melting(SLM) method.
Material and Method:Thirty bar-shaped Co-Cr metal substructures were fabricated using type 4(n=10, Group-T4) and type 5(n=10, Group-T5) alloys with SLE method, using metal ingot with casting method(n=10, Group-D). The microstructure of metal ingot and alloy powders was analyzed by X-ray diffraction(XRD). Feldspathic porcelain was applied at the center of each framework and fired. MC bond strength(MPa) of all frameworks was measured using three-point bending testing. MC bond strength data were analyzed using a one-way analysis of variance and the Tamhane T2 post hoc test(α=0.05). Fractured metal-ceramic interface of two specimens from each group was examined using energy dispersive X-ray spectroscopy and a stereo microscope
Results:Group-T5 (25.62 ±2.02) showed significantly lower MC bond strength than Group-D (37.28 ± 4.46; P=0.000016) and group T4 (32.82 ± 2.85; P=0.00019). After the bending test, it was confirmed that the amount of porcelain residue at the metal interface was highest in Group D and least in Group-T5.
Conclusion: The findings of this study showed that the alloy type may affect the MC bond strength of substructures fabricated using SLE.
