Electropolish in 5 Easy Steps - NuGenTec’s EP NiTi is Perfect for Electropolishingmedical device

NuGenTec is a one stop shop for electropolishing.  NuGenTec’s EP NiTi creates a microscopically smooth, corrosion-free surface every single time it is used for electropolishing.  This article will walk you through what electropolishing is and how to incorporate it into your process in 5 simple steps.

What is Electropolishing?

Electropolishing uses a voltage in a conductive solution to pull undesirable buildup, scale, burrs and embedded contaminants from the surface of metals.  Unlike mechanical finishing processes, NuGenTec’s EP NiTi never smears, stresses, bends or fractures the crystalline structure of a metal surface. The process improves corrosion resistance, removing layers to reveal a stress-free surface with the desired smoothness and luster while increasing passivity.

Electropolish in 5 Steps

  1. Alkaline Cleaning

First, your metal will need to be cleaned. We recommend using a NuGenTec specially formulated alkaline cleaner. After the initial alkaline cleaning, rinse with DI Water.
  1. Acidic Cleaning

Next, your metal will need an acidic treatment to remove scale and oxides.  We recommend the following specially formulated acidic cleaners: After this acidic cleaning, rinse with DI Water.
  1. Wick Away Water

Now, remove any residual water using a quick isopropyl alcohol rinse.
  1. Electropolish

Use NuGenTec EP NiTi to electropolish and leave a microscopically smooth surface.  After electropolishing, rinse with DI Water.
  1. Passivation (Optional)

Dip the part in nitric acid for passivation, then rinse with DI Water.
Note: Passivation is an optional step, as an oxide layer will reform naturally.

Why use NuGenTec EP NiTi?

NuGenTec EP NiTi is proven to leave smooth microfinishes every time while remaining less costly than competitors.  NuGenTec EP NiTi does NOT require cryogenic cooling, and is less hygroscopic than conventional electropolishing solutions, allowing for longer bath life.
