Corrosion is the gradual destruction of materials (usually metals) by chemical reaction with its environment. In the most common use of the word‚ this means electrochemical oxidation of metals in reaction with an oxidant such as oxygen. Rusting‚ the formation of iron oxides‚ is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal. Corrosion can also occur in materials other than metals‚ such as ceramics or polymers‚ although

Production and applications Titanium and titanium alloys powders Titanium possesses an exclusive combination of low density‚ good mechanical properties at room and elevated temperatures and good corrosion resistance. Titanium and its alloys are used extensively in aerospace‚biomedical industries and in other industrial applications. However‚ titanium ingots are expensive to produce and fabricate. Another problem is connected with segregation in highly alloyed titanium materials. The high cooling

ABSTRACT Sharing core knowledge in international collaborations could be a disadvantage due to the possibility of information leak and duplication of products and services around the world. The idea of sharing core knowledge is a disadvantage in the global economy for both the employer and employees. Many products and services have been duplicated in China due to the fast transfer of information. Obstacles in cultural differences can be overcome through education and experience through trial

Nucor Corporation (A) We are a cyclical business... Basically when you are at the peak of the cycle—times are good‚ interest rates are low‚ people are building—our margins increase. When we go to the trough‚ of course‚ the margins are squeezed. But over the last 25 years Nucor has never had a losing quarter. Not only a losing quarter‚ we have never had a losing month or a losing 1 week. —John D. Correnti‚ President and CEO‚ Nucor In 1998‚ Nucor was a Fortune 500 company with 6‚900 employees
