Unlike traditional cutting tools, which are cut, shaved, and shaped from blank ingots, powder-metal tools are built from fine metallic particles, imbuing them with several advantages
A new development in cutting tools has been made for machining aluminum. Hybrid PVD coatings consisting of a super hard TiSiN base layer and a low friction CrCx/a-C:H top layer are used on cutting tools where the combination of low friction and resistance to abrasion is required. When machining aluminum silicon, CrCx/a-C:H resists the adhesion and galling of aluminum to the cutting tool by reducing friction and TiSiN strongly resists abrasive wear.
