Metal Improvement 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.

Metal Improvement Company developed its laser peening process
in conjunction with the Lawrence Livermore National Laboratory.
Our laser peening process uses a unique high energy Nd:glass laser
in conjunction with precision robotics to provide consistent and
repeatable coverage of the square laser spots in the desired areas
of the parts to be laser peened.
Metal Improvement Company operates laser peening facilities in the
United States and the United Kingdom. For large stationary parts,
our Mobile Laser Peening Facility enables application of the laser
peening technology at the customer's site.
