Yücel, A. H., Yılmaz, A., Bakkal, M. & Kuzu, A. T. (2023). Tribo-corrosion behavior of electroplating, nitrocarburizing, and QPQ processes on barrel finishing. Materials Testing, 65(11), 1713-1720. doi:10.1515/mt-2023-0056Özet
In this study, the effects of nitrocarburizing, QPQ, and Cr coating on the surface properties of 32CrMoV12-10 gun barrels are discussed. Hardness measurements, pin-on-disc tests, and anodic polarization tests were performed to examine the hardness values, wear resistance, friction coefficient, and corrosion resistance. The hardness of the specimen treated with QPQ was found to be the highest. Comparing the hardness profiles, it was observed that the casing depth of the nitrocarburized sample was shallower than that of the QPQ-treated sample. The pin-on-disc test revealed that the nitrocarburized sample exhibited a high coefficient of friction, while the Cr-coated sample showed the lowest coefficient of friction. Analyzing the Tafel polarization curve, it was determined that the nitrocarburized and QPQ-treated specimens demonstrated similar levels of corrosion resistance. However, it can be noted that the QPQ-treated specimen had a slightly lower corrosion rate.

An experimental and theoretical work on the seismic behavior of a reinforced concrete frame
Agyemang, Christabel Akosua Sakyiwaa Osei (Işık Üniversitesi, 2019-01-18)Corrosion of reinforcements embedded in concrete is one of the numerous causes of deterioration in reinforced concrete structures. In an earthquake prone region, corroded structures become more vulnerable to early failure ... -
