Polymeric coatings have superiority over the other coating techniques in terms of applicability on different materials, cost and effectiveness. Epoxy-based polymeric coatings have become widespread application in industries such as automotive, manufacturing, construction, electronics, due to their high wear and corrosion resistance, good chemical and thermal stability, and especially very good adhesive properties. In this study, the wear behavior of epoxy coatings applied to steel disc specimens were investigated at 5, 10, and 15 N loads and 300, 600, and 900 seconds in accordance with ASTM G99-17 standard. The coefficients of friction were determined experimentally. Compared to aluminum-filled Epoxy 1, mineral-filled Epoxy 2 performed better at increased wear times and loads. It has been observed that 10% boron carbide (B4C) additive in Epoxy 1 coatings has a positive effect on long wear times, while 20% B4C additive deteriorates the physical structure, thus reducing the wear resistance. When the results obtained are evaluated, Epoxy 2 lost the least mass at long wear times and increasing loads.

Epoksi Esaslı Polimerik Kaplamaların Aşınma Davranışlarının İncelenmesi

Öz

Polimerik kaplamalar farklı malzemelere uygulanabilirliği, maliyeti ve etkinliği açısından diğer kaplama tekniklerine göre üstünlüğü bulunmaktadır. Epoksi esaslı polimerik kaplamaların yüksek aşınma ve korozyon direncine, iyi bir kimyasal ve termal kararlılığa, özellikle çok iyi yapıştırıcı özelliğine sahip olması nedeniyle otomotiv, imalat, inşaat, elektronik gibi endüstrilerde kullanımı yaygınlaşmıştır. Bu çalışmada, ASTM G99-17 standardına uygun olarak 5, 10 ve 15 N yük ve 300, 600, 900 s sürelerde çelik disk numunelere uygulanan epoksi kaplamaların aşınma davranışı incelenmiştir. Sürtünme katsayıları deneysel olarak belirlenmiştir. Alüminyum dolgulu Epoksi 1’e kıyasla mineral dolgulu Epoksi 2, artan aşınma sürelerinde ve yüklerde daha iyi performans göstermiştir. Epoksi 1 kaplamalarda %10 bor karbür (B4C) katkısının uzun aşınma sürelerinde olumlu etkisinin olduğu, %20 B4C katkısının ise fiziksel yapıyı bozduğu, dolayısıyla aşınma direncini düşürdüğü görülmüştür. Elde edilen sonuçlar değerlendirildiğinde, uzun aşınma sürelerinde ve artan yüklerde en az kütle kaybeden mineral dolgulu Epoksi 2 olmuştur.
