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
Cu-MgO Composites
Metal matrix composites reinforced with ceramic particles can be interesting for a range of applications due to their strength performance at high temperatures and a relatively low thermal expansion potential.
Manufacturing of Cu-MgO composites critically requires that the raw materials have a very high level of purity (99.5-99.9%) to achieve the desired manufacturing results. Continue reading
The Vacuum Die Casting (VDC) Process: Part One
Vacuum die casted materials have many applications in the automotive industry as well as a number of other commercial industrial sectors.
The main benefits of VDC as opposed to other more traditional methods of casting include a higher quality surface finish, improved mechanical properties and an overall better finished product stability. Continue reading
The Nitrocarburizing Process: Part Two
Nitrocarburizing is a surface hardening process which has several key advantages related to the efficiency in application and also in terms of producing a consistent and stable finished product.
The micro-hardness of surface treated materials using nitrocarburizing can have an increased surface hardness at a ratio of 1.3 to 1.5. Continue reading
