Ark sprey tekniği ile özlü tel kullanılarak üretilen farklı iki tür kaplamanın aşınma davranışının incelenmesi

Abstract

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

Abstract

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.
