pros and cons of weathering steel:: "Weathering" means that due to their chemical compositions‚ these steels exhibit increased resistance to atmospheric corrosion compared to unalloyed steels. This is because the steel forms a protective layer on its surface under the influence of the weather. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates

Aluminum GuttersOf all the types of gutters to choose from‚ there is a very good reason why aluminum dominates the gutter market. The metal is corrosion-resistant‚ lightweight‚ easy to work with‚ available in wide range of colors‚ and less expensive than the other alternatives. Copper GuttersCopper gutters will not hold up that much better or last longer than aluminum gutters for the added cost. There are certain long term and short term advantages to copper gutters‚ as long as they are installed

[CATHODIC PROTECTION/BM] CATHODIC PROTECTION P E FRANCIS 1 INTRODUCTION The first practical use of cathodic protection is generally credited to Sir Humphrey Davy in the 1820s. Davy’s advice was sought by the Royal Navy in investigating the corrosion of copper sheeting used for cladding the hulls of naval vessels. Davy found that he could preserve copper in sea water by the attachment of small quantities of iron or zinc; the copper became‚ as Davy put it‚ “cathodically protected”. The

Detailed Technical explanation: For selection of material of a centrifugal pump shaft‚ following criteria to be considered: i) Endurance Limit - as high as possible ii) Corrosion resistance - yes depends on fluid type and contact with shaft iii) Elongation - as low as possible The endurance limit is the stress below which the shaft will withstand an infinite number of stress reversals without failure. Since one stress reversal

Rust inhibitor that when added to liquids decreases the corrosion rates of a material. The researchers proposed for a rust inhibitor made of extract of squash seeds to prove if it is applicable as

entirely to rust and disintegrate. Surface rust is flaky and friable‚ and provides no protection to the underlying iron‚ unlike the formation of patina on copper surfaces. Rusting is the common term for corrosion of iron and its alloys‚ such as steel. Many other metals undergo equivalent corrosion‚ but the resulting oxides are not commonly called rust. Other forms of rust exist‚ like the result of reactions between iron and chloride in an environment deprived of oxygen – rebar used in underwater concrete
