A phosphate conversion coating is a type of protective coating that is applied to metal surfaces. The coating is created by a chemical reaction between the metal surface and a phosphoric acid solution ...

Bubbles created by pressurized water can directed at surfaces and trigger cavitation, the continued creation and collapse of bubbles. The addition of an ultrasonic transducer helps reinforce this ...

Although magnesium alloys are used extensively, the high corrosion rates are a big drawback. They corrode rapidly in highly chlorinated solutions such as human body fluid. This is a massive problem ...

Conversion coatings are coating layers applied to the surface of a metal substrate to enhance its appearance and improve physical and chemical properties, such as corrosion resistance and paint ...

EPA has amended the list of hazardous wastes by modifying the scope of the EPA Hazardous Waste No. F019. The code applies to wastewater treatment sludges from the chemical conversion coating of ...

Organic chemists have developed a process that allows them to turn biomass into a high-quality coating using light, oxygen and UV light. This process combines a renewable source with green chemistry ...

Many new materials have been developed, but steel remains the principal construction material for automobiles, appliances, and industrial machinery. Because of steel's vulnerability to attack by ...
