Zn-40Al-2Cu-2Si alaşımının mekanik ve tribolojik özelliklerinin korelasyonu

Öz

Zn-40Al-2Cu-2Si alaşımının mekanik ve tribolojik özellikleri ilişkilendirilmeye çalışıldı ve bu özellikler arasındaki ilişkiler lineer regresyon analizi ile belirlendi. Bu alaşımın mekanik ve tribolojik özellikleri arasındaki ilişkilerin doğrusal veya basit doğrusal denklemlerle ifade edilebildiği gözlendi. Bu ilişkiler alaşımın sertliği ve çekme mukavemeti arttıkça sürtünme katsayısının, çalışma sıcaklığının ve aşınma hacminin azaldığını ancak ortalama yüzey pürüzlülüğünün arttığını göstermiştir. Bu gözlemler, alaşımın mikro yapısı ve mekanik özellikleri, adezyon teorisi ve Archard aşınma kanununa dayandırılarak açıklanmıştır.

Correlation of mechanical and tribological properties of Zn-40Al-2Cu-2Si alloy

Öz

An attempt was made to correlate mechanical and tribological properties of Zn-40Al-2Cu-2Si alloy and the relationships between these properties were determined by linear regression analysis. The relationships between mechanical and tribological properties of this alloy were observed to be expressed by linear or simple straight-line equations. These relationships showed that as the hardness and the tensile strength of the alloy increase the friction coefficient, working temperature, and wear volume of it decrease but its average surface roughness increases. These observations were explained in terms of microstructure and mechanical properties of the alloy, adhesion theory of friction and the Archard wear law.
