Engine Technology
Using less solution and chemicals, and
generating very little waste, as well as reductions
in the carbon costs of emissions,
transport, and shipping, it's a more sustainable
option. The reduction in fumes
and hazardous waste disposal also delivers
a safer, healthier working environment.
Turbine interstage case from a PW100 engine that has been remanufactured through selective electroplating
using SIFCO ASC's AeroNikl® 250.
manufacturing process, the part was
pre-baked and electroless nickel coated
before being post-baked.
After completion, it was discovered
that the 0.125 " slot was oversized.
Rather than stripping and/or replating
the part, the customer worked with the
SIFCO ASC team to use selective plating
so the slot would meet the required
specification. After plating with nickel,
the part was baked for a minimum
of eight hours at 375°F. The masking
and plating operations of each part
amounted to less than ten minutes, a far
faster and more cost-effective process
than stripping and replating the part.
Reducing Environmental Impact
As well as extending the service life of
assets, saving money and materials versus
the cost of replacement, reducing
scrappage and improving process efficiency,
selective plating also offers substantial
environmental benefits.
Maximizing Uptime, Minimizing Costs
Remanufacturing undoubtedly offers
a cost-effective and resource-efficient
way to extend the service life of machines
and equipment. Opting for selective
plating offers further benefits, reducing
downtime and offering distinct
process and environmental efficiencies
versus other plating methods.
Selective brush plating has dramatically
evolved from its origins of touching
up existing plating jobs and is now
considered an overarching term describing
a highly technical process used for
repairing or improving surface properties
in an array of circumstances. Its
benefits commonly include increased
wear resistance, surface hardness and
low electrical contact resistance, or corrosion
protection, so much so that it is
often now specified in the initial engineering
design specification as well as
being called out for component repair.
