SUMMARY
The fiberizing spinner disks work in extreme conditions. They are exposed to influence of combustion gases,
very high temperatures up to 1000°C, and liquid boron-silicon glass. Up today used spinner disks are made of
Inconel 625 alloys but their durability is insufficient. Surface engineering method are implemented to improve
the disks durability. The recent studies carried on glass fiberizing machines are presented. The investigations
concern the application of intermetallic layers of NiAl type to protect the spinner disk against external environment.
It has been shown these layers improve the lifetime of spinner disk and they are better then standard
disks.
Keywords
Surface engineering, composite layers, intermetallic phases, glass fiberizing process, erosion and corrosion
resistance in the environment of liquid glass.
