Successful plasma cutting counts on consumables

Jul 09, 2010· If you don't change out the electrode and instead run it to failure mode, which means it really won't cut anymore, you're actually burning through the copper now because the hafnium is gone. The arc looks like an ugly, green glow, if you can even cut at all. The whole top of the electrode …

Hafnium - Wikipedia

Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals.Its existence was predicted by Dmitri Mendeleev in 1869, though it was not identified until 1923, by Coster and Hevesy, making it the last stable element to be discovered.

Tetrakis (ethylmethylamido) hafnium(IV) (TEMAHf), tetrakis (ethylmethylamido) zirconium(IV) (TEMAZr), and ozone were the precursors for Hf, Zr, and O, respectively. The growth rate per cycle was 0.98 Å cycle −1 and 1 Å cycle −1 for HfO 2 and ZrO 2, respectively. A 50 nm-thick TiN top electrode was formed on the deposited HZO layer by DC ...

Hypertherm, Inc. Why spend more on Hypertherm Powermax Plasma? because this cooler gas serves as a shield to protect the copper nozzle from melting. Another item we try to protect from heat is the tiny pin sized piece of hafnium at the tip of your electrode.Hafnium melts at around 3,000 degrees. During cutting, when the plasma arc is at 25,000 degrees, this hafnium is in molten state.

Aug 10, 2019· As it wears little pieces fall out and you get a divot/hole in the end of the electrode. The Hafnium is only about 1/8" deep so you have to keep this in mind before making long cuts or cutting out something on a CNC table. The time to change the electrode is when the divot/pit/hole in the end of the electrode get to be 1/16" deep or so.

Hafnium - Element information, properties and uses ...

Hafnium is not all that uncommon compared to many other exotic elements. It occurs to the extent of 5.8 ppm of the Earth's upper crust by weight. The reason why it took a long time to isolate is that its atoms have almost the identical size to those of zirconium, along with which it typically occurs in minerals.
