ST2 - Surface Treatment Technologies, Inc.
Company Background

ST2 was founded in 1998 as a new source for emerging coating and surfacing technologies for metals and alloys. At present, we offer two new surface technologies that fill major needs in the materials community. Laser Induced Surface Improvement (LISIsm) represents a major advancement in laser surface alloying, and Electro-Spark Alloying (ESA) offers an unsurpassed combination of benefits in wear, erosion, repair, and corrosion protection for metals and alloys.


ST2 will innovate, develop, mature, and transition to industry advanced surface treatment technologies for wear, erosion, thermal, and corrosion protection of metals and ceramics.

ST2 will provide these capabilities as a: job shop, turn key facility for industry, or ST2-staffed facility in a customer location.

ST2 is an authorized representative of TechnoCoat International Co., Ltd.
