The Process

The Coating process centers around a basic pickling reaction. When the metal comes into contact with a solution of phosphoric acid it depletes the hydronium ions. This raises the pH and causes the dissolved salt to separate out of the solution and set onto the surface of the metal. It's important to us to continually update our machines in order to ensure our ability to provide cutting-edge solutions. A.R. Machining considers zinc phosphate coating services as an important element in our desire to be a turnkey provider. Often a part that is lathed or milled must also undergo this coating process as well. Our capacity to do this in-house allows us to simplify the experience for our clients.

We are ISO 9001 certified and ITAR registered. Contact us today to find out more!
