De-e-Ion Zapper machines

Surface deposit and create graded nano-porous alloy combinations with the Cascade De-e-Ion Machines.

De-e-Ion Zapper machines are employed for surface coatings and for creating unique nanomaterials. Examples of antibacterial coating objectives or special coatings made without vacuum at very high speeds are pictorially shown below in rows 2 and 3.

Continuous HardCoating and Rapid Brazing Practices

Typical Comments:

The high-speed, high-temperature ramp is very helpful. As per our discussion with the braze alloy manufacturer, one significant problem often faced is the microstructure coarseness because of many hours at high temperatures (typical to traditional multi-hour furnace brazing cycles). This is the cause for the tungsten carbide particle size to increase during traditional furnace heat-treatment sequences, and then the metallurgical bond integrity reduces drastically. Similarly, any boron carbide particles remain extremely small and well-bonded, as do nano-alumina after the bonding. Rapid heat-up and rapid cool-down are a must for the future.

“One-minute hard-facing operation replaces 48 hr. operations! We also do not need nitrogen or argon atmosphere.”

“What I like about the Cascade e-ion process is that it allows for rapid continuous production instead of batch production.

Tool bit bonding by brazing is efficient. With the Cascade e-Ion, the high integrity of the tungsten (carbide) alloy fusion bond with the base steel is very acceptable. When the glue is of such high integrity and tough (i.e., does not activate or allows cracks to propagate), one can quench rapidly after the e-Ion CleanElectricFlame™ exposure.

“I was impressed to see the clean and high integrity interface between WC-Co and stainless steel… .The technology of the e-ion Plasma seems to be great”.

Wear-resistant surfaces may be made within seconds or minutes with e-Ion Plasma by immersing in Plume, representing an increase of several folds in productivity with lower capital cost and operating costs. Below are typical hardfacing interface microstructures obtained with tungsten carbide nano and hardfacing/hard surfacing alloy on a stainless steel substrate.

The surfaces below of n-WC were obtained after short exposure to CleanElectricFlame™. Competitive processes are often noted to produce much coarser microstructures. Nano-grained cemented tungsten carbide (n-WC) is currently being researched for many potential applications. The Cascade
