Investigation of Liquid Additives on the Nano-Hardness of NiFe during Polishing

Abstract

For the optimization of polishing processes, the knowledge of the effectiveness of additives on the surface binding is essential. The nano-hardness was used as an indication for the most adequate acid used as additives. For analyzing the nano-hardness, nanoindentation tests were performed. This paper describes the investigations on the nano-hardness of NiFe affected by hydrochloric acid (HCl) and nitric acid (HNO3) used as liquid additives during a polishing process.
