What Is Metal Corrosion and Why Does It Occur?

Filiform corrosion -- corrosion that occurs when water gets under a coating such as paint. Galvanic Corrosion: This can occur when two different metals are located together in a liquid electrolyte such as salt water. In essence, one metal's molecules are drawn toward the other metal, leading to corrosion in only one of the two metals.

What Causes Corrosion? CSL Silicones Inc.

Sep 12, 2016· What Is Corrosion? Corrosion is a natural process that involves the deterioration of metal components. According to NACE International, corrosion is “the destruction of a substance (usually a metal) or its properties because of a reaction with its environment.”This ultimately causes potentially severe damage to your building or application and can become very costly to repair.

Causes and Prevention of Corrosion on Welded Joints

Jul 11, 2017· The metallurgical, physical and chemical changes caused by the welding process affect the corrosion resistance of the weld. This leads to both the heat affected zone (HAZ) and the weld metal corroding faster or slower than the base metal. Cases of uniform corrosion across the base metal and weld metal, or the base metal corroding and the weld metal remaining unaffected, are also possible.

Metal fume fever Wikipedia

Metal fume fever, also known as brass founders' ague, brass shakes, zinc shakes, galvie flu, metal dust fever, Welding Shivers, or Monday morning fever, is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are heated.

Marine: Guidelines For the Use of Copper Alloys In Seawater

Reinhart found that copper and its alloys of aluminum, silicon, tin, beryllium, and nickel had significantly lower long-term corrosion rates after 18 months compared to those specimens measured after only 6 months of exposure to seawater (Figure 3). 3 The only exception was Alloy C28000, Muntz metal, which exhibited a slightly higher corrosion rate after 18 months as compared to 6 months.
