What are the regulatory requirements for surface hardened medical implants?

While through-hardened steel offers an incredible degree of toughness and increased resistance to corrosive agents, the process makes the steel more brittle. Jan 14, 2025 ... Surface hardening involves hardening the material on the outside faces of a part, leaving the inside at the material's natural hardness level. One common treatment used to increase the surface hardness of such steels and to minimise galling is to Nitride the steel by Plasma or Salt Bath Nitriding. This ... Bogachev, I. (2022). Influence of surface hardening on single crystal nickel-based superalloys [Apollo - University of Cambridge Repository]. Apr 12, 2010 ... So my concern is how to harden the surface to make it less absorbing for the sound wave. Any of you considered that? For a start I thought about ... May 9, 2023 ... Mid-infrared frequency comb spectroscopy shines the way to dynamic process control of plasma nitriding. Aug 5, 2024 ... Effects of surface hardening by laser shock peening and shot peening on a nickel-based single-crystal superalloy CMSX-4. Hakeem, A. H., Morar ... To understand stress or casehardening, the manner in which a board dries needs to be considered. During drying, the surface loses moisture first; moisture from ... surface hardening ... surface hardening, treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains ...
