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.
