Abstract

Through with current study the friction coefficient values for steel-aluminum alloy system in high contact pressures and low speed conditions have been obtained. To aim this goal a new arrangement of friction test apparatus which already was offered in literature has been fabricated. Towards, the effects of surface roughness and applied normal load on friction coefficient have been investigated. The results clearly revealed that friction coefficient is significantly influenced by applied normal load and reduces with increasing in load. Furthermore, surface roughness influences friction coefficient; but its effect is not as important as applied normal load. Finally, the suggested theoretical friction models in literature are compared with an experimental model of this study

Özet

Bu çalışma ile, yüksek temas basınçları ve düşük hız koşullarında çelik alüminyum alaşım sistemi için sürtünme katsayısı değerleri elde edilmiştir. Bu amaca yönelik olarak, daha önce literatürde sunulan sürtünme test cihazlarının yeni bir düzenlemesi yapılmış, yüzey pürüzlülüğünün ve uygulanan normal yükün sürtünme katsayısı üzerindeki etkileri araştırılmıştır. Sonuçlar açıkça göstermektedir ki, sürtünme katsayısı, uygulanan normal yükten oldukça etkilenmekte ve yük arttıkça azalmaktadır. Ayrıca, yüzey pürüzlülüğü sürtünme katsayısını da etkilemektedir. Ancak etkisi, uygulanan normal yük kadar önemli değildir. Son olarak literatürde önerilen teorik sürtünme modelleri, bu çalışmanın deneysel modeli ile karşılaştırılmıştır
