Investigation of the physical properties of armor steel after cataphoresis coating

Öz

It is very important that the materials generally used in the defense industry are suitable for environmental conditions, have a long service life, and do not lose their functionality. The resistance of armor steels to environmental conditions and corrosion is increased by coating. In this study, 'Miilux 500' armor steel was used. 'Cataphoresis coating', which has high resistance to environmental conditions, was selected as the coating method. In this study, it was observed that the corrosion resistance of armor steel, which is indispensable for the defense industry, is resistant to salt fog for 480 hours with cataphoresis coating. In the hardness measurement test and tensile test applied to see the values affected by the heat input during cataphoresis coating, it is evaluated that there are deteriorating features compared to the value given in the product catalogs. In the current situation, the applicability of cataphoresis coating on armor steel has been shown, provided that the superior corrosion effect and the deteriorating material strength values after heat input, the design area and expectations are evaluated.

Zırh çeliğinin kataforez kaplama sonrasında fiziksel özelliklerinin araştırılması

Öz

Savunma sanayinde genel olarak kullanılan malzemelerin çevre koşullarına uygun olması, uzun ömürlü olması ve işlevselliğini kaybetmemesi oldukça önemlidir. Zırh çeliklerinin çevre koşullarına ve korozyona karşı dayanıklılığı kaplama ile arttırılmaktadır. Bu çalışmada 'Miilux 500' zırh çeliği kullanılmıştır. Kaplama yöntemi olarak çevre koşullarına karşı yüksek dayanımı olan 'Kataforez kaplama' seçilmiştir. Bu çalışmada, savunma sanayinin vazgeçilmezi olan zırh çeliğinin korozyon direncinin, kataforez kaplama ile 480 saat tuz sisi etkisine dayanıklı olduğu görülmüştür. Kataforez kaplama sırasında maruz kalınan ısı girdisinin etkilediği değerleri görmek için uygulanan sertlik ölçüm testi ve çekme deneyinde, ürün kataloglarında verilen değerine göre kötüye giden özellikler olduğu değerlendirilmektedir. Mevcut durumda üstün korozyon etkisi ve ısı girdisi sonrası kötüye giden malzeme mukavemet değerleri, tasarım alanı ve beklentilerin değerlendirilmesi koşuluyla zırh çeliği üzerine kataforez kaplamanın uygulanabilirliği gösterilmiştir.
