  • Publication number: 20220097175
    Abstract: Disclosed is a method for extending service life of a sacrificial-layer-free aluminum alloy wheel by laser shock, comprising: performing finite element analysis each position of the wheel under actual working conditions; connecting the to-be-peened wheel to a fixture on a robot; determining laser shock peening parameters; upon laser shock, performing cleaning treatment on the shocked wheel to remove surface ablating; and performing paint spraying treatment on the processed aluminum alloy wheel. The method provided by the present disclosure can not only improve surface hardness of the aluminum alloy wheel, but also form a residual compressive stress layer on a subsurface, thereby restraining crack propagation, prolonging the service life of an aluminum alloy wheel hub and improving stability of the hub.
