AC 43.13-1B
(2) Rinse the area in cold, clean tap
water.
(3) Activate the area with reverse cur
rent, 7 to 10 volts, in conjunction with the
proper activating solution until a uniform,
gray-to-black surface is obtained.
(4) Rinse thoroughly in cold, clean tap
water.
(5) Immediately electroplate to color
while the area is still wet, using the appropriate
nickel solution.
(1) Electroclean the area using direct
current until water does not break on the sur
face. This electroclean process should be ac
complished at 12 to 20 volts using the appro
priate electrocleaning solution.
(2) Rinse the area in cold, clean tap
water.
(3) Activate the surface using direct
current for 1 to 2 minutes, using the activating
solution, and accomplish at 6 to 20 volts.
(4) Do not rinse.
(6) Rinse thoroughly.
(7) Immediately continue plating with
any other solution to desired thickness.
(8) Rinse and dry.
k. Plating on Copper and Copper Base
Alloys.
(1) Electroclean the area using direct
current until water does not break on the sur
face. The electroclean process should be ac
complished at 8 to 12 volts using the appropri
ate electroclean solution.
(2) Rinse the area in cold, clean tap
water.
(3) Immediately electroplate the area
with any of the plating solutions, except silver.
Silver requires an undercoat.
(5) Immediately nickel-flash the surface
to a thickness of 0.00005 to 0.0001 inch, using
the appropriate nickel solution.
(6) Rinse thoroughly.
(7) Immediately continue plating with
any other solution to desired thickness.
(8) Rinse and dry.
m. Plating on Low-Carbon Steels (Heat
Treated to 180,000 psi).
(1) Electroclean the area using direct
current until water does not break on the sur
face. This electroclean process should be ac
complished at 12 to 20 volts, using the appro
priate electrocleaning solution.
(2) Rinse the area in cold, clean tap
water.
(4) Rinse and dry.
l. Plating on 300 and 400 Series Stain
less Steels, Nickel Base Alloys, Chrome Base
Alloys, High Nickel Ferrous Alloys, Cobalt
Base Alloys, Nickel Plate, and Chrome
Plate.
(3) Reverse-current etch at 8 to
10 volts, using the appropriate activating solu
tion, until a uniform gray surface is obtained.
(4) Rinse thoroughly.
