  • Publication number: 20220009054
    Abstract: A surface treatment method includes a step of irradiating a workpiece with a pulsed laser beam through a transparent liquid and a step of causing particles to collide with a heat-affected layer developed on a surface layer portion of the workpiece in the step of irradiating. The particles each has a core made of an elastic body and abrasive grains provided on a surface of the core.

  • Publication number: 20120294756
    Abstract: Shots made from a zinc-based alloy is provided, wherein no risk for explosion caused by powder dusts exists. They achieve a high performance in deflashing and grinding and cleaning by shot blasting and a high ability to create a high compressive residual stress. The lost amounts of them by shooting are small. The shots are made from a zinc-based alloy that contains three components that include A1 of 0.5 to 6.5 mass % and Cu of 0.5 to 4.5 mass % as additional elements, or that contains four components that further include Mg of 0.01 to 0.2 mass % as additional elements, wherein the ratio of the mass of A1 to Cu (A1/Cu) is 1.0 to 13.0, wherein the total amount of A1 and Cu (A1+Cu) is 1.5 to 10.5 mass %, and wherein the Vickers hardness of the shots is 90 to 190 HV.
