Laser peening (LP), or laser shock peening (LSP), is a surface engineering process used to impart beneficial residual stresses in materials. The deep, high-magnitude compressive residual stresses induced by laser peening increase the resistance of materials to surface-related failures, such as fatigue, fretting fatigue, and stress corrosion cracking.
Dr. Allan Clauer, an original patent holder of the laser peening process, [3] and a Battelle inventor of the laser shock peening process, joined LSPT as Vice-President later in 1995. In 1996 to 1999, LSPT assembled and delivered three high power ND: Glass laser peening systems to General Electric Aviation in Cincinnati, Ohio.
Metal Improvement Company LLC, part of Curtiss-Wright, is a company specializing in metal surface treatments.. MIC provides multiple technical services for the metal treatment industry, including thermal spray, solid film lubricant and parylene coatings, and materials testing services; but is best known for its legacy shot peening technology, which can enhance the performance of metal ...
In metallurgy, peening is the process of working a metal's surface to improve its material properties, usually by mechanical means, such as hammer blows, by blasting with shot (shot peening), focusing light (laser peening), or in recent years, with water column impacts (water jet peening) and cavitation jets (cavitation peening).

The cold work temperature produced from this process is typically minimal; similar to the cold work produced by laser peening, but a great deal less than shot peening, gravity peening or, deep rolling. Cold work is particularly important because the higher the cold work temperatures at the surface of a component, the more vulnerable to elevated ...
Shot peening, bombarding metal parts with small spherical media; Laser peening, focusing lasers on the surface of a metal part; Peening (scythe blade), peening a scythe or sickle blade as a step in the sharpening process; Steel Belt: Shot Peening, a remedial solution for deformed steel belts
Because peening typically produces larger surface features than sand-blasting, the resulting effect is more pronounced. Shot peening and abrasive blasting can apply materials on metal surfaces. When the shot or grit particles are blasted through a powder or liquid containing the desired surface coating, the impact plates or coats the workpiece ...
Laser metal deposition (LMD) is an additive manufacturing process in which a feedstock material (typically a powder) is melted with a laser and then deposited onto a substrate. [1] A variety of pure metals and alloys can be used as the feedstock, as well as composite materials such as metal matrix composites .
