Abstract:

 In this study, aluminum coating process was performed on Monel 400 alloy at a temperature of 600C using the low-temperature pack cementation method for durations of 2, 4, and 6 hours. The mixture for the coating consisted of metallic Al powder as the aluminum source, Al2O3 as the inert filler, and Ammonium Chloride NH4Cl as the activator. The formed coatings were characterized using Scanning Electron Microscopy SEM and Energy Dispersive Spectroscopy EDS analyses to examine their microstructures, and phase analyses were conducted using and X-Ray Difraction Analyses XRD. SEM analysis revealed that the coating layers were homogeneous, compact, and pore-free, demonstrating a strong bond between the coating and the matrix. The thickness of the coating layer was measured from the surface to the matrix, and it was observed to vary between 4 µm and 10 µm. It was determined that 600C was sufficient for the accumulation of an aluminide layer and a successful coating layer was obtained. The hardness values of the alumina layer formed on the surface were measured, and an increase in hardness values was observed with increasing process duration and temperature.

 Bu çalışmada, Monel400 alaşım üzerinde 600C sıcaklıkta, 2, 4 ve 6 saatlik süreler boyunca düşük sıcaklıkta kutu sementasyon yöntemi ile alüminyum kaplama işlemi gerçekleştirilmiştir. Pota karışımı; alüminyum kaynağı olarak metalik Al tozu, inert dolgu olarak Al2O3 ve aktivatör olarak Amonyum Klorür NH4Cl kullanılarak hazırlanmıştır. Oluşan kaplamaların mikro yapıları SEM ve EDS analizleri ile karakterize edilmiş, XRD analizi ile faz analizleri gerçekleştirilmiştir. SEM analizi, kaplama tabakalarının homojen, kompakt ve gözeneksiz olduğunu ve kaplama ile matris arasında sağlam bir yapışma olduğunu ortaya koymuştur. Kaplama tabakasının kalınlığı yüzeyden matrise doğru ölçülmüş ve değerlerin 4 µm ile 10 µm arasında değiştiği gözlenmiştir. 600Cnin alüminid tabakasının birikmesi için yeterli olduğu ve başarılı bir kaplama tabakasının elde edildiği tespit edilmiştir. Yüzeyde oluşturulan aluminit tabakasının sertlik değerleri ölçülmüş ve artan işlem süresi ve sıcaklıkla birlikte sertlik değerlerinde artış gözlenmiştir.
