Description:

A newly invented technology (patent pending) provides convincing evidence of its potential to successfully respond to two areas of interest new and simple no-emission chrome plating and long-life coatings that have reduced environmental impact in both manufacture and use. Over one year of laboratory development and testing demonstrate that the response to both inquires will be positive. The purpose of this SBIR project is to investigate and prove the extent of applicability of the technology. The process is called Laser Induced Surface Improvement (LISI) and is performed by alloying precursor materials into an underlying substrate using the laser as a heat source. Permanent chromium-rich surfaces with a controlled thickness can be generated in an entirely environmentally friendly process, i.e., no harmful effluents or residuals. Several other precursor materials have been successfully used in the surface alloys on a variety of substrate materials. Unlike some competing techniques, LISI produces a nonporous, crack-free surface without need of a special environment for application. Preprocess cleaning of the substrate material is minimal, further reducing both costs and environmental concerns. The resulting molecular bond assures no delamination, chipping, or pealing of the protective surface. Testing has demonstrated surface protection from corrosion, erosion, impact, and thermal cycling.
