Download or read book Cadmium Plating Versus Other Coatings to Prevent Corrosion written by R. A. Farrara and published by . This book was released on 1984 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electrodeposited cadmium coating used to prevent corrosion of screws can cause hydrogen embrittlement type failures. Protective coatings applied to screws by processes other than electrodeposition were tested for corrosion resistance (5% salt spray test). The corrosion resistance of cadmium plated screws was significantly superior to the other coatings selected as possible candidates for replacing cadmium. (Author).

Download or read book The Performance of Three Alternative Coatings to Electroplated Cadmium for Corrosion Protection in Fastener Applications written by and published by . This book was released on 1999 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Army uses cadmium over a broad range of applications, including the production, maintenance, and repair of weapons systems and related components. The useful properties of this element have made it the number one choice for fasteners and similar components where corrosion resistance and lubricity are a concern. However, cadmium is a known carcinogen and poses health risks to those coming in contact with it. Executive Order 12856, "Federal Compliance With Right-to-Know Laws and Pollution Prevention Requirements," was enacted in 1993 with the intent of reducing the total release of toxic chemicals into the environment by 50% by 1999. As such, intense research efforts have been underway to develop a coating or coating system that provides similar, if not better, properties than cadmium. ARL examined three alternatives to cadmium for corrosion protection in AH-64 fastener applications, including ion-vapor-deposited (IVD) aluminum, a MIL-T-83483 antiseize compound, and a MIL-C-16173 corrosion preventative compound. It was concluded that the antiseize compound and the corrosion preventative compound were not adequate replacements for cadmium based upon unacceptable fastener and aluminum block corrosion. IVD was deemed comparable to cadmium based upon the torque values, fastener corrosion, and block corrosion results.

Download or read book A Comparison of the Corrosion Behavior and Protective Value of Electrodeposited Zinc and Cadmium Coatings on Steel written by A. Mendizza and published by . This book was released on 1957 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrodeposited coatings of both zinc and cadmium are commonly used to prevent the rusting of steel parts exposed to the atmosphere. During the period of World War II the armed services and, particularly, the Navy Department were inclined to favor the use of cadmium for this purpose, as judged from their general specifications for that time. Because of the acute shortage of cadmium and cadmium plating facilities during World War II it was necessary to give serious consideration to the substitution of zinc wherever possible. This resulted in considerable controversy as to the relative merits of the two metals, particularly their protective value when applied in equal thicknesses. Previous work (1-3) had shown zinc coatings to be superior to cadmium coatings when exposed to industrial atmospheres. The tests of Blum, Strausser, and Brenner also showed zinc coatings to have somewhat longer protective life than cadmium coatings in mild, rural locations such as State College, Pa., and urban sites such as Washington, D. C. While only comparatively thin coatings were involved, it was concluded from this same work that the difference in protective value between the two kinds of coatings in marine locations was not significant. On the other hand, the results of many comparative salt spray tests had shown cadmium coatings to be markedly superior to zinc coatings under the particular conditions prevailing in a salt spray cabinet. Undoubtedly the results of these accelerated tests contributed in a large measure to the generally prevalent attitude favoring cadmium coatings in marine atmospheres. The work reported herein was undertaken to determine the relative protective value of zinc and cadmium coatings in a wide variety of environments including accelerated corrosion tests.
Download or read book Metallic Coatings for Corrosion Control written by V. E. Carter and published by Newnes. This book was released on 2013-10-22 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallic Coatings for Corrosion Control describes how metal coatings can control corrosion, the selection process, preparations, suitability, limitations, and how coatings are applied. The book reviews the nature of corrosion, the forms of corrosion (even general, uneven general, even local, narrow pits, cracking), electrochemical mechanism of corrosion, effects of discontinuities in coatings, and economic considerations of coating. It describes pretreatments (such as removal of superficial corrosion, abrading, polishing), the coating processes (molten or spray application, chemical or vapor deposition, diffusion coating), and also coating performance. The rate of corrosion on different metals such as aluminum, cadmium, copper, gold, silver, or tin depends on the presence of an oxide film, solubility, electrodeposits, or tarnish blackening. Gold is resistant to corrosion and tarnishing except in aqua regia. The book recommends the following when the engineer is selecting a type of coating: the environment where it is exposed, the service life required, the substrate material, shape or size of the article, its decorative appeal, mechanical factors, and if there will be any subsequent fabrication. The book is useful for students of civil, structural, and mechanical engineering. Designers and technicians of industrial machinery or maritime equipment will also profit from reading it.

Download or read book Graham s Electroplating Engineering Handbook written by L.J. Durney and published by Springer Science & Business Media. This book was released on 1984-11-30 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: As an instructor in various finishing courses, I have frequently made the statement over the years that "In the field of metal finishing there is very little black and white, just a great deal of grey. It is the purpose of the instructor to familiarize the student with the beacons that will guide him through this fog. " To a very considerable extent, a handbook such as this serves a similar purpose. It is also subject to similar limitations. Providing all the required information would result in a multi-volume encyclopedia rather than a usable handbook. In the pages that follow, you will therefore find frequent references to other sources where more detailed explanations or information can be found. The present goal is proper guidance and the provision ofthe most frequently required facts, not everything that is available. In the 13 years since the last edition, changes in the finishing industry have been profound but in one sense have resulted in simplifying matters rather than complicating them. Because technology has advanced to a level of complexity rendering "home brew" impracti cal in many cases, dependence on proprietary compounds has become common. Therefore, detailed solution compositions are often no longer significant or even practical. It is thus more important to provide instruction about the factors that affect the choice of the most suitable type of proprietary material.
