Abstract:The fretting wear properties of a nanocrystalline layer with laser shock peening (LSP) on the surface of Ti–6Al–4V (TC4) alloy were investigated to improve the fretting friction performance at 25 °C and 500 °C. The fretting operation characteristics and material damage mechanism of the LSP–TC4 alloy were investigated through a friction dissipation model and two kinds of operation fretting models. The contact morphology and three-body behaviour on the surface were also revealed. The wear resistance performances… Show more
