Vacuum Brazing: Part Two

A critical step in any brazing process is the successful removal of oxide films before the process begins and the vacuum brazing process is no different.
In order to prepare the mating surfaces for brazing the ‘clean-up’ process needs to be initiated and this typically happens most effectively between 600 and 850°C. Continue reading

Iron Spark Plasma Sintering (SPS): Part One

Spark Plasma Sintering (SPS) is a sintering technique which is well matched to mechanically milled materials such as tool steels due to its low temperature and short cycle time.
Tool steels have been specifically manufactured to exhibit exceptionally high strain hardening, a characteristic which can be undone by high temperature sintering processes such as hot isostatic pressing. Continue reading

Vacuum Brazing: Part One

Vacuum brazing is categorized as a technique by its protected sealed environment under vacuum and extremely high temperatures greater than 800°C.
The main advantages of using vacuum brazing include achieving high integrity hermetic joints with minimal distortion. Continue reading
