At all stages, the reader is urged to develop a knowledge of what material is being treated, when to stop a procedure, Resources 133 and when to call on the help of specialists. · Index 139 The idea for this book arose from a workshop on the care of historic instruments from the museum perspective organized by the Museums & Galleries Commission of the United Kingdom, and hosted by the Hornirnan Museum in London in 1994. Information on this subject is urgently needed because, with the current interest in performing music of earlier periods in a historically informed fashion, the historic instru­ ments themselves have become the focus of attention. Although from the museum perspective there is no fw1damental difference between a historic musical instrument and any other complex, fw'lctioning museum object, it is sometimes necessary to regarc;l instruments as a special case. This results from a quite natural focus _upon fw1ction as opposed to form. At the risk of generalizing, the instrument owner or custodian with a professional music background is likely to approach an instrument from the fw'lctional per­ spective, directing attention to its use in producing music, while the custo­ dian with a background in museum studies, materials science or conserva­ tion is more likely to see the object in terms of its materials of fabrication and the means available for analyzing, stabilizing, and preserving them. While neither of these opposing approaches, if carried to their extreme, is truly tenable, the focus on fw'lctionality without regard to preservation causes the information embodied in historic instrwnents to become a din'linishing resource. In order to preserve their information value for the future, guidelines on their care and maintenance are essential. A number of organizations have raised awareness of the vuh1erability of musical instruments. The International Musical Instrument Committee Ethics and the of ICOM (CIMCIM) has produced Recommendations for Regulating the Access to Musicallnstmments in Public Collections and Recommendations for Use of Instruments & 1 Consei1Jation of Musicallnstmments. The Musewns Galleries Commission has published Museums of Music and Standards in the Museum Care of Musicallnstmments. A compilation of literature on musical instrument conservation and technology has been co-published by the International Institute for Conservation and the Getty Conservation Institute in a dedi­ cated vohune of Art and Archaeology Technical Abstracts.

To use the chart, align the metal to be assessed (for the risk of corrosion) in the left column with the Contact Metal listed in the upper row; green represents a lower risk and red represents a higher risk. For a more specific assessment of the risk of galvanic corrosion, please check with other sources. Please understand that green represents "lower risk" not "no risk." It should be noted that if sacrificial plating is incorporated in the fastener design, then galvanic action can result in the deterioration of the sacrificial coating, rather than of the fastener. We would advise that the suggested fasteners for dissimilar-metal applications would incorporate our GRABBERGARD® coating which utilizes both barrier and sacrificial coatings to minimize the chance and/or rate of corrosion. The barrier coating used to encapsulate our zinc and anti-corrosion chemical bonding agents minimize the opportunity for contact to occur, thereby further minimizing the risk of corrosion.

    R CORROSION Information C Galvanic ACTION Galvanic CORROSION - compatible metals charts To minimize galvanic corrosion, fasteners should be considered based on their material compatibility with the substrates. Determine the materials being fastened and choose a fastener material that is close in proximity on the chart. The closer together the material are on the chart the less galvanic action will occur. Metals listed on the top of the chart (anotic) will corrode faster than the metals on the bottom of the chart (cathodic).

  • Corrosion Basics
    CORROSION BASICS (from Swain (1996) and Schultz (1997)) What is corrosion? • Webster’s Dictionary - corrode (v.) To eat away or be eaten away gradually, especially by chemical action. • NACE Corrosion Basics - corrosion may be defined as the deterioration of a material (usually a metal) because of a reaction with the environment. Why do metals corrode? Most metals are found in nature as ores. The manufacturing process of converting these ores into metals involves the input of energy. During the corrosion reaction the energy added in manufacturing is released, and the metal is returned to its oxide state. Metal Ore reduction (add electrons)→ Metal oxidation (strip electrons)→ Corrosion Products In the marine environment, the corrosion process generally takes place in aqueous solutions and is therefore electrochemical in nature. Corrosion consequences Economic - corrosion results in the loss of $8 - $126 billion annually in the U.S. alone. This impact is primarily the result of: 1. Downtime 2. Product Loss 3. Efficiency Loss 4. Contamination 5. Overdesign Safety / Loss of Life Corrosion can lead to catastrophic system failures which endanger human life and health. Examples include a 1967 bridge collapse in West Virginia which killed 46. The collapse was attributed to stress corrosion cracking (SCC). In another example, the fuselage of an airliner in Hawaii ripped open due to the combined action of stress and atmospheric corrosion. Corrosion cell Corrosion occurs due to the formation of electrochemical cells. In order for the corrosion reaction to occur five things are necessary. If any of these factors are eliminated, galvanic corrosion will not occur. THIS IS THE KEY TO CORROSION CONTROL! The necessary factors for corrosion to proceed are: 1.

Joshi and Alan Meier Received: 3 February 2016; Accepted: 6 April 2016; Published: 19 April 2016 Abstract: The nature of microgalvanic couple driven corrosion of brazed joints was investigated. 316L stainless steel samples were joined using Cu-Ag-Ti and Cu-Ag-In-Ti braze alloys. Phase and elemental composition across each braze and parent metal interface was characterized and scanning Kelvin probe force microscopy (SKPFM) was used to map the Volta potential differences. Co-localization of SKPFM with Energy Dispersive Spectroscopy (EDS) measurements enabled spatially resolved correlation of potential differences with composition and subsequent galvanic corrosion behavior. Following exposure to the aggressive solution, corrosion damage morphology was characterized to determine the mode of attack and likely initiation areas. When exposed to 0.6 M NaCl, corrosion occurred at the braze-316L interface preceded by preferential dissolution of the Cu-rich phase within the braze alloy. Braze corrosion was driven by galvanic couples between the braze alloys and stainless steel as well as between different phases within the braze microstructure.

The mean time to failure can be short or long, depending on the combination of conditions 1 and 2. This report provides the galvanic series for general metals and compatibility. In addition, it lists preventative measures to avoid issues in open loop cooling water systems. 2 GALVANIC CORROSION PREVENTION GUIDE FOR WATER COOLING SYSTEMS Summary and Background This report details best practices for reducing the risk of galvanic corrosion in mechani- cal and electro-mechanical cooling system designs. Galvanic corrosion, sometimes called bimetallic or dissimilar metal corrosion, is when one metal in a system experiences corrosion due to an electro-chemical reaction with a different metal and an electrolyte in the same system. Galvanic corrosion has been experienced in designs with dissimilar metals used in Advanced Energy products that use water cooling. Because conditions that promote gal- vanic reactions can exist inside Advanced Energy units due to the environment and running conditions, some simple best practices will help reduce the risk of galvanic corrosion failure.
