QUICK WEARING PART FOR ARC TORCH, PLASMA TORCH OR PLASMA CUTTING TORCH, AND ALSO ARC TORCH, PLASMA TORCH OR PLASMA CUTTING TORCH WITH THE SPECIFIED PART AND METHOD OF PLASMA CUTTING, AS WELL AS METHOD OF MANUFACTURING ELECTRODE FOR ARC TORCH, PLASMA TORCH OR PLASMA CUTTING TORCH Russian patent published in 2024 - IPC H05H1/26 

FIELD: torches.

SUBSTANCE: invention relates to a wear part for an arc torch, plasma torch or plasma cutting torch, as well as to an arc torch, plasma torch and plasma cutting torch with this part and to a plasma cutting method, as well as to a method for manufacturing an electrode for a torch and can be used for thermal processing of metallic and non-metallic materials, in particular, for example, for cutting, welding, heating. The wearing part, at least one part or section of the wearing part, consists of an alloy of silver and zirconium, the proportion of zirconium being at least 1% of the mass of the wearing part, or part, or section and a maximum of 5% of the mass of the wearing part, or part, or section, wherein 100% of the remaining mass fraction of the wear part or part or section is made of at least 60% copper, and the emissive insert (7.3) consists of at least 90% volume or mass of hafnium, or zirconium, or tungsten.

EFFECT: increasing the service life of wear parts, in particular electrodes, nozzles and protective nozzle tips for an arc torch, plasma torch or plasma cutting torch, while preventing the sudden end of the material processing process, leading to further unsuitability of the material for use.
