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.
