Hafnium - Wikipedia

Hafnium is also used as the electrode in plasma cutting because of its ability to shed electrons into air. The high energy content of 178m2 Hf was the concern of a DARPA-funded program in the US. This program determined that the possibility of using a nuclear isomer of hafnium ...


What is Plasma Cutting? - esabna.com

The electrode is usually made of copper, but with a metal insert at the point where the arc attaches. That's because the copper would melt too fast if the arc attached directly to it. ... So when using Oxygen or compressed air as the cut gas, the insert is made of a material called Hafnium. Hafnium lasts a lot longer in the presence of Oxygen ...


Experimental Study of Consumption of Hafnium Electrode in ...

12%Hafnium (Hf) is used as a refractory cathode material for thermionic emission in a high-temperature region. The consumption of an Hf electrode was investigated by measuring the concavity depth on the Hf electrodes after operations. These measurements were performed under several operating conditions.

Electrode wear in air and oxygen plasma l Hypertherm

The electrode carries the DC power from the plasma power supply to the metal plate. It is typically comprised of a copper or copper/silver composite holder that contains an emissive element of hafnium-a high melting point metal that will sustain an arc in air and oxygen cutting environments.

SilverPlus Electrodes | Hypertherm

SilverPlus® electrodes incorporate a hafnium/silver interface at the point of electrical transfer. The hafnium/silver extracts more heat and has a stronger bond than hafnium/copper. The result: dramatically longer electrode and nozzle life – increasing productivity and lowering operating costs by reducing the number of consumable sets used ...


SilverPlus Electrodes | Hypertherm

SilverPlus® electrodes utilize a hafnium/silver interface at the point of electrical transfer. The hafnium/silver interface extracts more heat and has a stronger bond, enabling a deeper pit depth in the hafnium. This means that you will get double the life compared to standard copper electrodes. …



Selecting plasma cutting consumables

The fact is, consumable wear is application-specific. Generally, you should replace standard all-copper electrodes when the hafnium pit depth reaches 0.040 in. Silver/hafnium interface electrodes can reach a pit depth of 0.080 in. safely before they need to be replaced. Your torch is too far (or too close) to the workpiece.

An indirect way to achieve comprehensive performance ...

The hafnium atom, with large atomic radius, is surrounded by soft electron clouds and has high chemical activity to attract oxygen ions. It facilitates the accumulation of more oxygen ions around the interface of the top electrode and the resistive switching layer, leading to lower current and Schottky conduction.

modulating the top electrode. During the crystallization process through annealing, the top electrode serves as a capping layer which prevents the volume expansion and shearing of the HfO 2 unit cell. It prevents the formation of the non-ferroelectric phase and helps to stabilize ferroelectricity. Typically, the TiN electrode is used.
