Plating Resources

The hard chrome industry was built on skills and techniques developed over generations, dating back to the mid-1920s. Eric Svenson Sr.The generations since perfected the process, allowing the trade to grow into an industry that’s critical for America’s economy and defense. This blossomed into an important trade that both smaller job shops and larger OEM operations apply. The technical knowledge was passed down from one generation to the next before those with the skills retired.

Chromic acid is the major ingredient for hard chrome baths. It’s also the most expensive component and is used at high concentrations, typically between 30-35 ounces per gallon (225-263 g/l). Eric Svenson Sr.Until recent years, the only form of chrome available for electroplating was chromium hydroxide (dry chromic acid), supplied in solid form and packaged in drums.

Next to air, water is the most important ingredient for life. Now consider that it’s also the main ‘chemical’ used in the plating bath. Its purity is essential for trouble-free hard chrome plating. Water purity should never be taken for granted. Purified water is preferred for new bath make-ups, rinsing, and replacing evaporative losses in the tanks. Municipal water supplies are the typical source for plating operations, although some shops have used well water as an alternative.
