Laser Peening
 

ɴȿ

LVI Technologies Inc. Company's laser peening process imparts a layer of beneficial residual compressive stress underneath the surface of metal components to help them better resist the detrimental effects of fatigue and corrosion.

 

In our laser peening process, a unique high energy laser is fired at the surface of a metal part to generate pressure pulses of one million pounds per square inch, which send shock waves through    the part.  Multiple firings of the laser in a pre-defined surface pattern will impart a layer of residual compressive stress that is four times deeper than that attainable from conventional peening treatments. Deeper levels of compressive stress provide greater resistance to potential fatigue and corrosion failures
