Plasma Spray Powders

DC plasma spray operates by creating an electric arc and passing a plasma gas through it. This creates an extremely high temperature plasma, which enables ceramics to meet their melting temperatures. Alloys International offers a range of common plasma spray powders to suit different application requirements.

DC Plasma Sprays

  • Electric arc formation — an electric arc is created and a plasma gas is passed through it
  • Extremely high temperature plasma — the process generates temperatures high enough to melt ceramic materials
  • Enables ceramic coatings — the extreme heat allows ceramics, which have very high melting points, to be applied as a thermal spray coating

How does DC plasma spray work?
DC plasma spray works by creating an electric arc and passing a plasma gas through it, generating an extremely high temperature plasma capable of melting ceramic materials for coating application.

Why is plasma spray used for ceramic coatings specifically?
Plasma spray generates extremely high temperatures, which enables ceramics to meet their melting temperatures — something lower-temperature thermal spray processes typically cannot achieve.

Who can advise on the right plasma spray powder for a specific application?
Alloys International's sales team can provide specific application expertise for selecting the right plasma spray powder.
