摘要
Release rates of chromium, nickel and iron from grade 304 stainless steel with three different surface finishes, BA, 2B and 2D, have been determined after exposure to artificial lysosomal fluid. Metal release rates are discussed in relation to corrosion resistance, compositional changes of the outermost surface film of the stainless steel and to measurements of the effective surface area and roughness. The total metal release decreased in the following sequence: 2D > 2B approximate to BA, and was primarily related to the electrochemically active surface area. No direct correlation was observed between corrosion resistance and metal release rates. (c) 2005 Elsevier Ltd. All rights reserved.
