Salt Spray Testing in the

The gradual degradation of metals by a chemical reaction is called Corrosion. In other words, a corrosive reaction would occur when a metal is exposed to an oxidant (oxygen) creating an electrochemical oxidation. Rusting of iron is one of the most common examples of corrosion that the general population is aware of. Since corrosion is common and can happen to most metals used commercially, theories and ways to protect metals from corrosion were developed. Applied coatings (paints, etc.) and reactive coatings (zinc, etc.) are some of the typical coatings used for the protection of metals from corrosion. Once the methods of protection from corrosion were developed, there was a need to test these processes to scale them on the benchmarks of time, cost effectiveness and overall performance. Salt spray testing was identified and accepted as the standardized corrosion test methodology. The salt spray test helps determine the resistance of the metal and coatings against corrosion.

Biggest Lies in Surety Bonding

Here are the 10 biggest lies in surety bonding: 1. "The surety is your partner and we are all in this together." OK and I have a bridge in Brooklyn to sell you. This is true until there's a claim or loss and then the surety is entitled to sue the contractor for recovery. After all, they are a "for-profit" company that must answer to its stockholders. They are not in business to lose money. In cases where collateral has been required by the surety, it will not be used to help the contractor finish the project. It is only used to help the surety perform the work with the replacement contractor in the event of default. 2. "We are requiring a 50% performance bond to save the contractors bonding capacity." Misplaced good intentions: Bond underwriters evaluate the contractors amount of remaining work, not the remaining bond amount.
