Exposure to air-based Cascade e-Ion plume produces a fine gold color coating (shown below for a biomedical insert screw) on biomedical Ti/6Al/4V alloy with the following EDAX spectrum.  Coating creation and refurbishment is greatly simplified.  Use just air for input gas as described below for the EDAX result or use nitrogen gas or forming gas as required.

Almost all customers who consider the Cascade e-Ion for an application or to GoldenBlue®  request Deburring of parts.


The Cascade e-Ion Plasma is used for Titanium Alloys (including multilayer graded peening), Co-Cr-Mo type biomedical alloys, stainless steel alloys, high density plastics, dental alloys, gold alloys, superalloys, or for surface and other conditioning of Nitinol, Ni-Ti, Ti-Al, Ti-6-2-4-2 (such as Ti-6Al-2Sn-4Zr-2 to 6Mo) shapes castings, forgings and many others.

Nitriding of Ti-6Al-4V with the Cascade e-Ion Plasma improves Ti6Al4V surface properties for biomedical use.  Please Contact Us for your specific application. MHI offers complex part manipulators from robotic arms to continuous belts.

Cascade e-Ion Models that are applicable for oxynitriding and surface coatings.  For nano-porous surfaces use the de-e-Ion machines.

Other uses of transition metal oxynitrides and rapid forming very smooth hard coatings with the Cascade e-ion include:

Tool-bit Industry such as drills, end-mills, broaching tools, rams, inserts, cutting tools, deep draw, cylinders like master pump, slides, bearings rollers and ball bearings.

Automobile or  sea-borne vehicles from use in related steel, aluminum and plastic industries that include  turbines, shafts, spindles, gears dies, extruders molds, bearings, crankshafts, camshafts, gears, pistons, cylinders, springs and valves, rings, dies and molds.

Molds in casting and plastic and die casting Industries.

Forging and forming industries for operations including forging and pressing which could include cold forging, shape forging for impressions, open die forging, hammering and bending.

The smoothness (low coefficient of friction) properties are particularly important for bearings and busings even when sealed.

MHI finds that chromium, iron, titanium (transition metal) oxy nitrides are particularly useful even when compared to regular nitrides as they work towards lubricity, low wear, low coefficient of friction, low galling and have a very attractive surface look and feel.  The cascade e-Ion plates ions continuously in air.  Please take advantage of this feature and be to your market first.
