The objective of this work is to verify the machining process behavior of the Cr3C2 25NiCr HVOF coating. which can be used for the automotive, aerospace industries and naval, improving the sufarce finish of the thermal spray. The coating is machined with a 12mm diameter carbide ball nose tool, in which the tool is parallel to the surface, with a cutting speed of 100m/min, and a feed of...

Electro-slag remelting is an important process to produce high quality tool steels. Thereby the slag composition has a strong effect on the remelting behavior in general and on the electric energy consumption as well as on the removal of non-metallic inclusion. Later aspect is strongly related to chemical reactions taking place between the slag and the metal and thereby determines the...

at the interacting surfaces, hence, limiting the tool life. The speed of chip sliding and contact pressure on the
tool dominate the magnitude of wear; therefore, these factors were considered in the developed interactive
friction model. Considering high heat generation results in a temperature...
