Nitorcarburizing is typically performed on steel components to improve surface hardness of the material via nitrogen dispersion.
One noteworthy finding however suggests that the corrosion resistance of the treated specimen was less than that of the control and untreated part. Continue reading
Boronizing is a surface treatment by which boron atoms are diffused into the surface of the metal in quantities exceeding the solubility limit.
Hardness is improved and thus wear resistance increased as well as a number of other advantages such as corrosion and oxidization resistance. Continue reading
There are five typical methods of bending currently used in industry today: rolling, incremental bending, hot bending, rotary-draw bending, and induction bending.
Although ISF is generally very slow, it is of interest because no or only a simple and cheap tool is required, making the process ideal for small-series production. Continue reading
Low superheat casting is similar to the better known SSM technique which can be applied primarily to produce billets with a low cost advantage.
In the LSC process, the alloy is rapidly solidified and cast with a low pouring temperature which is typically just above the liquidus temperature. Continue reading
Additive manufacturing is a relatively recent manufacturing method which has become a key area of interest in multiple industrial sectors.
Deriving from CAD models the process can be used to create solid yet highly complex parts and pushes towards a tool-less manufacturing environment meaning improved quality and better efficiency in many cases. Continue reading
Soft magnetic materials are essential components in many devices and are indispensable in modern electrical engineering and electronics.
In recent years there has been significant progress made in the field of soft magnetic materials. Amorphous and nano-crystalline metals represent an expansion and enhancement of the range of soft magnetic alloys. Continue reading
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
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
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
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
