The average end roughness and the material removal reached with the process were charted versus the pH of the different mixtures. This paper will review the technique used to generate the improved isotropic surface finish and will additionally review some of the engineering advantages that can be imparted to metal-to-metal contact surfaces. Isotropic mass finishing ensures a part’s surface will have no discernible marks, lines or patterns. The isotropic etching of various. isotropic finishing Post by sbcharlie » Fri Aug 03, 2018 12:00 pm I was wonder if many of you know or use this process on internal engine parts and transmission gears. Vibratory finishing techniques are popular, cost-effective, and less labor-intensive. ). Machinists use metal surface finishing for protective chemical reactions on. What is isotropic etching process? Isotropic etching is a method commonly used in semiconductors to remove material from a substrate via a chemical process using an etchant substance.
