Use the SmartPlasma device. Compare with DLC and other Plasma methods. Create nanoscale Carbon Nitrides, Nitrogen Carbon, Borides, and Mixed Borides. Hard and Smooth Oxynitride Colors. High Vickers. Compound layers in steel form in situ or by graded layer processing. Use on chromium, molybdenum, manganese steels, titanium alloys, zirconium alloys, and diamonds. Oxynitrides are among the most important new materials for low-wear surfaces, plasmonics, solar cells, and glass coatings. The cascade e-ion beam enables Deburring. Create Non-stick surfaces for steel and cast iron or treat cell phone glass. The Cascade e-ion allows continuous, seamless processing for improved tool and die performance. Welcome to the world of two-dimensional materials formation of various types.

Microstructure, EDAX, and XPS results.

The Cascade e-ion processes allow continuous use. Traditional furnace-based batch treatment techniques could be expensive. Batch processes are often inefficient and costly due to high furnace and facilities costs. Compare processing time in seconds/minutes with long processing times in furnaces and the associated colossal energy consumption. Other expenses from batch coaters include frequent maintenance and repair with specialized labor. Extra steps like plasma cleaning or blanking parts may be required, which are mostly unnecessary with the Cascade e-Ion process. XPS and other delicate electronic probes display fine structure, depth of ionic penetration, and new phase formations, which are advantageously used.

The application of titanium, zirconium, iron, and steel alloys is limited by low shear strength, high coefficient of friction, low hardness, and poor wear resistance. The cascade e-ion is the first process to offer processing within seconds with no space limitations. Some of the ROIs are astounding. Some beneficial phases of iron nitrocarbides, carbonitride, smooth oxynitrides, compound phases/layers for hardness and high wear resistance, epsilon phases, and titania or other antimicrobial nanostructures may be experienced. Experience the possibilities of rapid bulk heat treating and quick brazing with meager operational costs  – often less than a cent per part.   Create conditions for chromium nitrides, titanium nitrides, tantalum, niobium and zirconium oxynitrides, manganese (oxy)nitrides, vanadium nitrides, oxycarbides, aluminides, aluminum/magnesium/silicon nitrides and oxynitrides (including composite combinations or particulate, fiber, functionally graded or grated layers). Lanthanum, perovskite Oxynitrides for photocatalytic power and photoconductivity. Ion nitride yittria zirconia films. Create functionally graded or grated layers with nanoscale oxynitrides, inorganic elements, and nitrides.   Change the adherence in organic molecules by plasma polymerization on goggles, plastics, mold surfaces, and other parts by direct application. Combust coal and biomass to lessen the release of aromatics and complete combustion. Please contact MHI.

Case Studies have discussed that range from tool bit reconditioning to the accessible surface improvement of steels and cast irons. Bearings, axles, rails, deep-dishes, pans, broaches, carbide drills, cast irons, simple parts like nail clippers and scissors, complex parts that hold up space mirrors, and much more can be GoldenBlue® treated effortlessly with the cascade e-ion plume. Enjoy the benefit of high temperatures to create smooth and hard surfaces that are now made easy.

Is there a simple way to tell if the Cascade e-Ion Plume treated part is smoother? When nitrided or oxy-nitrided with the GoldenBlue® treatment, the swage-lock, high-temperature bolt, ball/roller bearing, or machine tool should make less noise when machining or putting on the nut.   Less noise is an indicator of smoothness.

How is wear reduced? Material loss by tribological processes causes wear. The GoldenBlue® reduces galling, adhesion, abrasion, and tribo-oxidation depending on the alloy. See samples in the auto industry for rapid new techniques for austempering and martempering.

The Cascade CleanElectricFlame® technology uses just electricity and air (or other gasses if required, like Nitrogen, Argon, or Forming Gas) leaving behind no residues. MHI’s Cascade e-Ion Plasma uses less energy, produces hardly any noise, and is safer than traditional heating methods. It is one of the most special plumes available. The Cascade e-Ion systems are available for use with hard alloys, plastics, metals, glass forming, ceramics, composites, and several other materials – even food or wood. The Cascade e-Ion devices can be used for sintering, for example, titanium and carbon mixed powders in minutes. Large surface plates are easily moved under the beam. The CleanElectricFlame® provides a Cascade e-Ion environment.

The Cascade e-Ion can bend, nitride, create surface borides like Zirconium diboride and alloys, and for inducing colorful smooth surface oxynitride of many materials including manganese, chromium, titanium, copper/ graphite, and glass.

A possible use for automotive axles, pistons, tappets, piston rings, valve stems, guides crankshafts with quick low-cost nitriding(O) – even for space re-entry surfacing. The CleanElectricFlame® provides a new type of reducing environment.  Even difficult materials like copper and tungsten-copper alloys have a shiny finish after the Cascade e-Ion plume treatment. In situ growth of nitrides and oxynitrides is a special “open” feature that only the plume from the Cascade e-ion can accomplish. Adopt early. Early-stage pricing and possible MHI partner financing are available.  MHI offers an attractive MHI-Never-Down program. Please ask for details on the Cascade e-Ion Models, like the unique MHI-Never-Down program warranty-type features and, if required, MHI Financing.

For Cascade e-Ion

– Heat up rate 100K/s (Kelvin per second).  Ionic heat transfer.
– Price per part for several small parts using only air and electric ~ 0.2US¢/part.

Price of Energy: The price of energy depends on the source but is not that different between different forms of energy that one can use (e.g. gas or electric). Comparisons are given for example on Duke Energy. In the US, when comparing gas and electric a rule of thumb is that gas energy is about 75% lower cost when compared with the same quantity of electric energy. However electric machines are generally much more efficient than gas heaters. For example, the OAB or Cascade e-ion can save you even 90% of traditional energy use in relevant applications. These new machines can dramatically influence operational costs. Often using electric heating is less polluting at the use point. Additionally, electric heaters can be efficiently/accurately controlled. Both KWhr and Therm are units of energy.

1kJ (KiloJoule) = 0.9485 BTU=0.0002778 kWhr. One Million BTU (MBTU) = 10.002 Therm (US). Electric energy is normally priced for every KWhr used, while gas is priced by the number of Therms used.

The Cascade e-Ion makes providing dross-reducing covers for melting metals extremely feasible. The DRO models are particularly well-designed for this type of solution. The cascade e-ion can make magnets better for corrosion resistance or high-temperature oxidation. How do you know that the surface is harder? Bounce the ball bearing and watch if it bounces higher than the non-coated bearing.

We may not yet have all the answers on every application, so we may not be sure if the Cascade e-Ion Plasma is always right for you. However, for most surfaces, the CleanElectricFlame provides the best plasma, ion-implantation, and modified chemical species, enough to warrant a trial (payment may be required) on your part. Regardless of whether we know what the treatment offers for a specific untested surface, we can certainly arrange to have your part treated during a live video conference. Contact MHI. It is worth a try!

Improved Energy Efficiency From:

a)  When the part or tool lasts longer or can be used at higher speeds.

b)  The tool requires a lesser number of replacements.

c)  When dry machining is possible. Dry machining has great potential for improved energy and resource efficiency.

d) Manufacturing tools are the lowest energy procedure, so the total energy cycle is minimal. ( with the Cascade e-Ion).
