= Low plasticity burnishing
{wiki=Low_plasticity_burnishing}
Low Plasticity Burnishing (LPB) is a surface enhancement technique used to improve the mechanical properties of materials, particularly metals. It involves the application of a hard, rounded tool to produce a plastic deformation in the surface layer of the material. This process creates compressive residual stresses, refines the microstructure, and enhances surface hardness, fatigue resistance, and wear properties.
