Abstract
Bu
çalışmada Zn-15Al-3Cu alaşımı kokil döküm yöntemiyle üretildi. Metalografik incelemeler
sonucunda bu alaşımın içyapısının β dendritleri ile a, η ve ε (CuZn4)
fazlarından oluştuğu görüldü. Alaşımın yağsız durumdaki sürtünme ve aşınma özellikleri
blok-disk esaslı bir aşınma deney düzeneğinde farklı basınç (1-5 MPa) ve kayma
hızlarında (0,5-2,5 ms-1) 2500 m’lik kayma yolu tamamlanıncaya kadar
incelendi. Alaşımın sürtünme katsayısının artan basınç
ile azaldığı, kayma hızından ise fazla etkilenmediği gözlendi. Aşınma ile
meydana gelen hacim kaybı ve sıcaklık değerlerinin artan basınç ve kayma
hızıyla arttığı görüldü. Ayrıca basınç ve kayma hızı arttıkça yüzeylerdeki
aşınma ve/veya hasar izlerinin daha belirgin hale geldiği görüldü. Aşınma
yüzeylerinin altında farklı mikroyapı ve mikrosertlik değerlerine sahip
tabakaların yer aldığı gözlendi. Bu tabakaların oluşumu gerilme etkisi ile
yüzey altında meydana gelen yapısal dönüşümlere ve aşınma parçacıklarının
yüzeye sıvanmalarına dayandırılarak açıklandı. Yüzeyde yer alan sıvama
tabakasının kalınlık ve mikrosertlik değerinin artan basınç ve kayma hızı ile
arttığı belirlendi. Basınç ve kayma hızının alaşımın tribolojik özellikleri
üzerindeki etkileri çalışma sırasında yapısal ve mekanik özelliklerde meydana
gelen değişimlere göre açıklandı.
