Lambda Technologies has taken surface enhancement to a new level designing and introducing residual stress distributions that improve component performance and damage tolerance without changing either the material or the component design. Lambda's patented Low Plasticity Burnishing (LPB) processing and related surface treatments can be used to improve performance, reduce maintenance costs, and allow material substitution in ways that were never before possible. Brief descriptions of the surface enhancement methods that are presently available, their benefits, limitations, relative cost and ease of use follow.
