Induction plasma can synthesize nanomaterial starting from different precursors either in the powder, liquid, or gaseous state. The high temperature and high heat transfer environment renders it possible to evaporate nearly any material. The controlled and rapid quench give rise to the formation of nano powders in the range of 20-100 nm. (more information process link to Technology/nanopowder)

The powder is evaporated in the induction plasma torch at high temperatures and allowed as it passes through the quench zone to resolidify rapidly. Tekna’s unique quenching zone permits the control of the nanoparticle size and synthesis of highest quality of nanopowders.

The nanopowder synthesis chamber is made of water-cooled, double wall stainless steel construction, with a air lock allowing a continuous withdrawal of the process powder without interruption of the operation of the system. Its internal surface is highly polished for easy cleaning and to deduce all types of contamination and memory effect.

A heat exchanger located between the powder processing chamber and the filter will cool the gas. The powder are separated from the flue gas in nanopowder filtration system and then removed from the system in a removable cup located at the bottom of the unit. The filtration module system can be equipped with a glove box for the safe manipulation of a nanopowder.

In option we can manufacture the inner liner of the reactor in Inconel or corrosive protection coating for better resistance to corrosive environment.
 

Induction plasma technology is particularly suited for the powder plasma treatment process because of the large volume of plasma, the axial feeding and the long particle residence time. In-flight melting of individual particles can create spherical particles, increase density, enhance purity, and alloy metals. (more information process link to Technology/spherical powder)

The chamber is made of stainless steel water-cooled, double wall construction, with an air lock powder collection canister, and a side gas exhaust port. The internal surface of the chamber can be mirror finished.

A heat exchanger located between the powder processing chamber and the filter will cool the gas. The powders are separated from the plasma gas by high efficiency filtration media. An automated blow back system allows a continuous cleaning of the filter and the collection of the fine powder at the bottom canister of the collector unit.

In option we can manufacture the inner liner of the reactor in Inconel or corrosive protection coating for better resistance to corrosive environment.
 

Tekna’s plasma spray coating system design is ideal for achieving thin or near-net shape deposition under controlled atmosphere. (more information on process link to Technology/coating)

The vacuum thermal spray coating chamber is water-cooled with a double wall, highly polished, stainless steel interior. The unit is designed to operate with non-corrosive gas. The chamber which is mounted horizontally is to be equipped with a hinged front door, a fixed backdoor, a top opening for the mounting of the RF plasma torch, a bottom port for gas exhaust, and two quartz observation windows.

The unit is equipped with a versatile 3 axis robotized manipulator to move and rotate the substrate below the plasma discharge under positive or vacuum pressure environment:
-    Lateral translation over given stroke at a variable speed.
-    Rotation around its horizontal axis with a variable speed.
-    Vertical translation allowing for the adjustment of the substrate.
