This is a weak, colorless, odorless and inorganic acid, commonly known as an accumulation of orthophosphoric acid molecules, H3O4P. In chemistry, it is known as an agent that can bind divalent cations. It is used as a cleaning and roughening agent in medicinal practices; it is used as an acidifying… View Full Term

An understanding of how cracks form and propagate enables us to design safer and more reliable structures at a lower cost.
By: Nemanja Pavlovic
Fracture is simply the separation of a material into several pieces due to an applied stress. The type of fracture (ductile or brittle) that a material will undergo depends mainly on its ability to deform before it cracks.

Stress concentration reduction in machine parts usually involves providing a smooth path for stress to flow through the component. This can be achieved by several methods, including reducing sharp corners and providing relief notches.
Discover the types and sources of electrical interference that accelerate corrosion in buried metallic structures such as pipelines, tanks and vessels.

Increasing surface roughness depth does not always ensure good coating adhesion. Here, we consider how adhesion ultimately depends on not only the energy that is used to create the contact, but also on the interaction existing in the contact interface.

In light of basic adhesion science, today’s surface profile measurement methods, standards and specifications have unique limitations in determining whether a proper surface profile has been achieved prior to coating.
Impressed current cathodic protection (ICCP) is necessary when stray electrical currents threaten to corrode metal equipment. This video explains the whole process.
