Surface Treatment Technologies Inc (ST2) was founded to be a new source for emerging coating and surfacing technologies for metals and alloys. The firm offers two new surface technologies that fill major needs in the materials community. The first, Laser Induced Surface Improvement (LISIsm) represents a major advancement in laser surface alloying. LISIsm is a controlled surface modification using a high energy laser for specific area modification. The surface is environmentally friendly and is not a coating, but is instead a re-alloying of the base metal surface. The second technology, Electro-Spark Alloying (ESA), is a controlled surface modification via pulsed micro-welding. The coatings are nano-composite structures that can be fused to base alloys, with unique corrosion and tribological properties. ESA offers a combination of benefits in wear, erosion, repair, and corrosion protection for metals and alloys.
