Ferroniyobyum ve Ferrobor İçeren Tozaltı Kaynak Tozları ile Elde Edilen Kaplamaların Mikroyapı ve Aşınma Özelliklerinin Araştırılması
Abstract
Bu çalışmada, SAE 1020 çelik yüzeylerde sert dolgu kaplama elde
etmek amacıyla, 4 farklı oranda ferroniyobyum ve ferrobor içeren tozaltı kaynak
tozları, S1 kaynak telleri ile kombine edilerek tozaltı kaynak testlerine tabi
tutulmuştur. Gerçekleştirilen kaynak testleri neticesinde; elde edilen
kaplamaların mikroyapı, sertlik ve aşınma özellikleri incelenmiştir. Artan
miktarlardaki ferroniyobyum ve ferroborun toz bünyesinde kullanılmasıyla elde
edilen kaplama mikroyapılarında yer alan borürlerin yüzdesi artmış, sertlikler
artmış ve kaplamaların aşınma kayıpları azalmıştır. En yüksek sertlikler %12
ferroniyobyum ve %10 ferrobor içeren kaynak tozu ile elde edilen kaplamada 48
HRC olarak tespit edilirken, en düşük sertlikler ise %3 ferroniyobyum ve %2.5
ferrobor içeren kaynak tozu ile elde edilen kaplamada 41 HRC olarak tespit
edilmiştir.

Microstructure and Wear Properties of Hardfacings Obtained Using Submerged Arc Welding Powders Containing Ferroniobium and Ferroboron
Abstract
In this study, submerged arc welding powders containing
ferroniobium and ferroboron at four different rates combined with
S1 welding wires subjected to the welding test with the aim of
hardfacing on SAE 1020 steel surface. As a results of welding tests,
microstructure, hardness and wear properties of hardfacings were
investigated. With an increase in amounts of ferroniobium and
ferroboron in welding powders, both percentage of boride structure
located in hardfacing microstructure were increased, and the
hardness increased. Therefore, the wear losses decreased. The
highest hardness result was determined with the hardfacing
obtained from the welding powder containing %12 ferroniobium
and %10 ferroboron as 48 HRC, the lowest hardness result was
determined with the hardfacing obtained from the welding powder
containing %3 ferroniobium and %2,5 ferroboron as 41 HRC
