One of the areas we are most proud of is our work to expand our coatings to the medical field. The ME-92 biochrome coating was developed specifically to provide a high quality chromium coating that could be used in the medical device industry.

During the global COVID-19 pandemic, when many businesses ceased operations, Armoloy of Rhose Island expanded operations, added a second shift and worked into the weekend to support a variety of businesses and industries that were essential to support global efforts to counter the pandemic. We are very proud of our employees who embraced the ‘essential worker’ role and helped process components for sterilization equipment, centrifuges, sanitizing wipes and more.


The Electrolizing®, Micro-E®, and AL-COAT® coatings are most often applied to OEM design engineering or to job shops for repair and maintenance, including plastic injection molding components. We are capable of stripping and re-applying coatings to save downtime.

Electrolizing® provides performance enhancement for metals to prevent failures. Our main goals are to:

  • Solve metal failure problems through metal failure prevention or mitigation
  • Improve repair and maintenance problems

Our engineers work with customers to achieve these goals and improve processes. We also offer a value add service where our coating is added to existing materials in order to create a premium product.


We work with customers to help engineer solutions. Our quality assurance staff can provide precise measurements of deposit thickness by using the latest advances in fluorescent x-ray technology, laser micrometers, and many other state of the art instruments.

Our innovation center in Dekalb, IL has a staff metallurgist on site and provides metallurgical science services including:

  • abrasion testing
  • hardness testing
  • porosity testing
  • friction testing
  • mini plating cell setup

We also have an Electrolizing® fulfillment center in South Carolina.


At Armoloy of Rhode Island we serve a global market and are capable of handling parts up to 8 ft long and 2 tons in weight. Some customers use our services for over 1 million parts per year and others for 1 part per year.
