Fretting fatigue (fatigue-wear) occurs when contact stresses cause cracks to form and continue to grow between two objects or surfaces in contact. By considering frictional abrasions and intermittent mechanical loads, the phenomenon of fretting fatigue can occur in vehicle engine parts. The presence of cyclic loads and the presence of wear in the engine cylinder head increase the probability of the fretting fatigue phenomenon. In this study, the effect of lubrication and abrasion force on the fretting fatigue behavior of the cylinder head aluminum alloy has been investigated. The results were also obtained to compare samples with and without nanoparticles. Microstructure and fracture surface were also examined by light microscopy and scanning electron microscopy. The results showed that lubrication and reduction of abrasive force improved the wear fatigue lifetime of cylinder head aluminum alloy. In addition, according to the results obtained from the diagram, the effect of oil and reduction of abrasive force, the lifetime of reinforced specimens was 7 and for cylinder head specimens 7000 times compared to the lifetime of aluminum specimens without lubricant and at contact force of 15 N.
