Suitable for a variety of metals

Electron beam hardening increases the load-bearing capacity of the wear surface and high wear areas of components. This is achieved by briefly supplying energy to change the structure of the surface layer (surface hardening). The benefits: Less wear and corrosion and a significantly longer service life.

This process is well suited for the hardening of steel and all other carbon metals. This includes cast iron and other metals that cannot be thermally hardened such as aluminum-, titanium-, copper-, magnesium- and nickel-based alloys. The use of electron beam hardening negates the need for costly post-processing. As the hardening process is digitally controlled, all processes are easy to automate and reproduce.

Exceptionally high hardening and hardness penetration depths can be achieved after prior soft machining and remelting.

Advantages at a glance

  • Wear protection and improved corrosion behavior
  • High productivity thanks to short treatment cycles
  • High dimensional and form stability
  • Components can be installed immediately after hardening
  • Easy to automate and reproduce due to digitally controlled process
  • Partial hardening of steel and other metals with defined energy transmission

Typical applications

  • Vehicle components (e.g. cam units, pump lobes, fitting contact surfaces)
  • Heavy wear areas on rotationally symmetrical components (e.g. bearing or valve seats in combustion engines), wear surfaces and edges (e.g. on attachments or forming die)
