PWPS has an extensive, proven history of producing industry-
leading technological solutions. This advantage is created
by applying proprietary technology to provide new and
innovative solutions for industrial customers.
PWPS has improved upon the OEM offering by designing
parts that minimize oxidation, creep, and metal temperature
ultimately extending part life and reducing operating costs.
PWPS parts incorporate several design changes to address
field distress issues including: optimized internal cooling to
reduce metal temperature without increasing cooling air
requirements; platform cooling to address platform thermal
mechanical fatigue (TMF); modified geometry to reduce
stresses that lead to cracking; blade tip cooling enhancements
to improve repairability at overhaul; and refined placement of
film cooling holes to address local areas of distress.
V94.3Ax 1st Stage Blade:
The 1st stage blade is manufactured using a proprietary
single crystal nickel superalloy tailored for large industrial
parts and licensed from Pratt and Whitney. PWPS uses a
metallic bond coat applied by High Velocity Oxy-Fuel (HVOF)
with a ceramic thermal barrier coating (TBC) top coat. This
coating reduces base metal temperature to provide superior
protection against oxidation, coating spallation, and TMF
cracking. A vapor phase aluminide coating licensed from Pratt
and Whitney provides improved oxidation and corrosion
resistance for the internal cooling passages.
V94.3Ax 2nd Stage Blade:
The 2nd stage blade is manufactured using a directionally
solidified nickel superalloy tailored for large industrial parts
and licensed from Pratt and Whitney. The 2nd stage blade
has a metallic bond coat applied by HVOF and a TBC top
coat. This combination of alloy and coating provides superior
protection against oxidation and TMF cracking. For improved
internal cooling passage oxidation and corrosion resistance,
this part also incorporates an aluminide coating licensed from
Pratt and Whitney on the internal cooling passages.
Bringing Advanced Aviation Engineering and Technology to the Industrial Market
PW Power Systems (PWPS) goal is to provide value-based gas turbine solutions by incorporating customer feedback
and component optimization with the advantage of more than 90 years of technological expertise.
PWPS leverages Pratt & Whitney® world-renowned hot-section technology to address the needs of the industrial
gas turbine customer.

V94.3Ax 3rd Stage Blade:
The 3rd stage blade is manufactured using René 80
commercially available equiaxed nickel superalloy. The 3rd
stage blade incorporates a coating, applied by HVOF with a
TBC top coat. This combination of alloy and coating provides
superior protection against oxidation and corrosion. For
improved internal cooling passage oxidation and corrosion
resistance, this part also incorporates an aluminide coating
licensed from Pratt and Whitney on the internal cooling
passages. The PWPS part provides optimized internal cooling
to reduce metal temperature without increasing cooling air
requirements.
V94.3Ax 4th Stage Blade:
The 4th stage blade is manufactured using René 80
commercially available equiaxed nickel superalloy. The 4th
stage blade incorporates a chromide coating applied with a
pack cementation process licensed from Pratt and Whitney.
This combination of alloy and coating provides superior
protection against corrosion.
V94.3Ax 1st Stage Vane:
The 1st stage vane is manufactured using a Mar-M-509
commercially available equiaxed cobalt superalloy. PWPS uses
a proprietary metallic bond coat applied by HVOF and a TBC
top coat. The TBC reduces base metal temperature, provides
superior protection against oxidation, coating spallation, and
TMF cracking.
V94.3Ax 2nd Stage Vane:
The 2nd stage vane is manufactured using René 80
commercially available equiaxed nickel superalloy. The 2nd
stage vane incorporates a metallic bond coat applied by HVOF
and a TBC top coat. This combination of alloy and coating
provides superior protection against oxidation and TMF
cracking. For improved internal cooling passage oxidation
and corrosion resistance, this part also incorporates a vapor
deposited aluminide coating licensed from Pratt and Whitney
on the internal cooling passages.
V94.3Ax 3rd Stage Vane:
The 3rd stage vane is manufactured using René 80
commercially available equiaxed nickel superalloy. The 3rd
stage vane incorporates a metallic bond coat applied by Air
Plasma Spray (APS) and a TBC top coat. This combination
of alloy and coating provides superior protection against
oxidation and TMF cracking. For improved internal cooling
passage oxidation and corrosion resistance, this part also
incorporates a vapor deposited aluminide coating licensed
from Pratt and Whitney.
V94.3Ax 4th Stage Vane:
The 4th stage vane is manufactured using René 80
commercially available equiaxed nickel superalloy. The 4th
stage vane incorporates a chromide coating applied with a
pack cementation process licensed from Pratt and Whitney.
This combination of alloy and coating provides superior
protection against oxidation and corrosion.
V94.3Ax 1st and 4th Stage Turbine Guide Ring Segments:
The 1st and 4th stage turbine guide ring segments are
manufactured using an IN-738 commercially available
equiaxed nickel superalloy. The 1st and 4th stage turbine
guide ring segments incorporate a metallic bond coating
applied by APS and a ceramic abradable seal coating. This
combination of alloy and coating provides superior protection
against oxidation.
