CWST THERMAL SPRAYING SERVICES

The three Curtiss-Wright Surface Technologies Thermal Spray Coating Divisions were acquired from the BASF Corporation in April of 2011.  Previously known as BASF Surface Technologies, the facilities have a rich history in the development of advanced thermal spray coatings for flight and industrial gas turbines, and trace their origin back to the original General Plasma, Inc. facility in East Windsor, CT, which was acquired by the Engelhard Corporation in 1994.

Today, Curtiss-Wright Surface Technology’s (CWST) facilities in East Windsor, CT; Wilmington, MA and Duncan, SC provide advanced GPX and APX thermal spray coatings for a variety of end use properties.

Curtiss-Wright ST Coatings Expertise
CWST GPX‚ and APX™ turbomachinery thermal spray coatings deliver technologies essential to today’s high performance, high quality industrial turbines, including:

Thermal Management
GPX Thermal Barrier Coatings can maximize turbine efficiency by allowing higher firing temperatures while reducing component thermal fatigue, warpage, oxidation and cracking. The combination of ceramic and superalloy constituents in GPX Thermal Barrier Coatings reflects heat back into the combustion gas path and insulates parts, effectively lowering their surface temperatures.

Wear Control
Wear due to vibration, friction, thermal gradients and pressure shortens the life of turbomachinery components, and if left unchecked, can cause expensive unscheduled outages. GPX Wear Control Coatings can prolong the life of critical turbomachinery parts by as much as 10 times. Anywhere metal touches metal is a candidate for GPX Wear Control.

Corrosion Control
Low Temperature
Corrosion of turbomachinery components costs operators billions of dollars every year through premature part failure and induced aerodynamic drag. APX Corrosion Prevention Coatings can dramatically reduce corrosion damage while providing a smooth aerodynamic surface on compressor blades and stator assemblies. Tough APX Coatings also provide resistance to erosion from dust and high velocity gases.

Corrosion Control
High Temperature
Turbine components exposed to corrosion at high temperatures (+ 1,000 °F) not only degrade faster than at lower temperatures, but also are subjected to cracking due to thermal fatigue and cycling. APX High Temperature Coatings are diffused into the substrate, creating a nearly impermeable oxide surface which can reduce scaling and cracks due to thermal cycling.

Oxidation Control
High temperature oxidation is a condition in gas turbines most responsible for premature failure of “hot section” components. As designers continue to raise turbine firing temperatures, superalloy components are nearing their theoretical limits. GPX Oxidation Resistant Coatings are extending these limits by impeding oxygen penetration of the component surface while providing a sacrificial layer capable of protecting the part between overhauls.

Solid Particle Erosion Control
Solid particle erosion claims tons of steam turbine components every year and is most responsible for premature turbine failure. Often coupled with foreign object damage, solid particle erosion can be controlled effectively when temperature, impingement angle, velocity and size of erosion particles have been considered. GPX Solid Particle Erosion Coatings are specifically designed and tested for this environment and have proven effective in extending the life of critical steam turbine parts.
