Ark sprey tekniği ile üretilen
kaplamalar öncelikli olarak korozyon ve aşınma direnci gerektiren uygulamalarda
yaygın bir şekilde kullanılmaktadır. Daha yüksek aşınma direnci gerektiren
uygulamalar için özlü teller aşınma plakalarına alternatif olarak tercih edilmektedir.
Bu çalışmada, ark püskürtme tekniği ile çelik (St 52) altlıkların üzerine Fe-Cr
esaslı ve yüksek karbür içeriğine sahip ticari özlü tellerden kaplamalar
üretilmiştir. Üretilen kaplamalar ASTM G133-05 standardına uygun olarak farklı
yük ve aşınma mesafelerinde test edilmiştir. Kaplama karakterizasyonu
sonrasında aşınma yüzeyleri ve aşınma kayıpları karşılaştırılmıştır. Aşınma
testlerinin sonucunda özlü teller ile kaplama yapmanın aşınma direncini önemli
oranda arttırdığı belirlenmiştir.

Investigation of wear behavior of two dıifferent types coatings by using cored wire with arc spray technique

Öz

Coatings produced by arc spray
technique are used primary in applications requiring corrosion and wear
resistance. Cored wires are preferred as alternative to wear plates for applications
where higher wear resistance is desired. In this work, coatings from commercial
cored wire with Fe-Cr based and high carbide content on steel (St 52)
substrates with arc spraying technique have been produced. The produced
coatings have been tested at different load and wear distances in accordance
with ASTM G133-05 standard. Wear surfaces and wear losses were compared after
coating characterization. As a result of the wear tests, it has been determined
that coating with core wires increases wear resistance considerably.
