In this vital industrial specialization, we rebuild
and restore all bearing surfaces and main journals
with pure chrome. With Coastal Plating
shape-conforming anodes and rotating fixtures, we
can put hard chrome plate exactly where it belongs
and not on thrust face or
radii. The chrome plated surfaces provide
restoration of highest quality and a face that will
resist wear, abrasion, galling, seizing and
corrosion. It will perform to you strictest
requirements under the severe conditions.
Chrome plated surfaces can stand up to the severe
demands of high-use, heavy machinery. With a
hardness of 66-70 on Rockwell's "C" scale, chrome
has a melting point of 3488 degrees Fahrenheit.
CHROME PLATING
IS DONE THROUGH ELECTRO-CHEMICAL REACTION. 3-6 VOLTS
ARE PASSED CONTINUOUSLY FROM LEAD ANODES THROUGH
CHROMIC ACID INTO THE FORGED CRANKSHAFT. CHROMIUM
IONS ARE THUS DRIVEN FROM THE SOLUTION AND PLATED
ONTO THE BEARING AND JOURNAL SURFACES ONLY OF THE
SHAFT, AS IT SLOWLY ROTATES IN THE PLATING TANK.
TOTAL AMPERAGE MAY RUN AS HIGH AS 4500 AMPS
DEPENDING ON THE SIZE OF THE CRANKSHAFT. OUR PLATING
TANKS RUN 24 HOURS A DAY, SEVEN DAYS A WEEK. EACH
CRANKSHAFT REQUIRES ABOUT 40 CONTINUOUS HOURS IN THE
TANK TO DEPOSIT ENOUGH CHROME FOR THE GRINDING. |
