The crystals in Sandvik Coromant's Inveio coating are oriented in the same direction, as shown by the uniform yellow color in this image.
Crystal persuasion: Inveio Technology discussed in Cutting Tool Engineering
By Alan Richter, Editor, Cutting Tool Engineering
A random arrangement is all well and good when it comes to avant-garde music, but the random crystal growth direction found in conventional CVD alumina cutting tool coatings can create weak areas where cracks form, shortening tool life. According to Sandvik Coromant Co., the new Inveio CVD alumina coating on its GC4325-grade inserts has a unidirectional crystal orientation—where every crystal is aligned in the same direction—that resolves that issue by…
