FIELD: process engineering.
SUBSTANCE: invention relates to laser cold working. First layer is applied on article billet. First layer does not contain cavities or bubbles with diameter exceeding 10 micrometres. First layer is evaporated or produced by dipping. Second layer is applied on first layer. Then, laser pulse is send onto second layer. Said pulse features sufficient power density for ablation of second layer section. Thereafter, plasma is ejected. Said plasma generates shock wave propagating onto first layer and billet for cold working. Whatever bubbles formed under top layers is isolated from surface to be cold worked.
EFFECT: smooth cold-worked surface.
