Plasma nitriding improves the wear resistance of a material by effectively altering the surface microstructure while maintaining adequate substrate properties.
Nitriding occurs when a bias voltage is applied to the work piece causing ions to collide with the surface and consequently creating the nitride effect. Continue reading
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
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
Aluminum is well established at the front of the pack with regards to providing the technological answer to the increasing challenges of light weighting whilst maintaining integrity of the material for the desired applications.
Semi solid rheocasting is a development within the casting sector which enables improved quality in die casting without increasing cost. Continue reading
