Overview Corrosion is defined as the deterioration of a material, usually a metal, because of a reaction with its environment and which requires the presence of an anode, a cathode, an electrolyte, and an electrical current. The annual cost of corrosion and... Learn More>>
Lubricating oils are used in machinery to reduce friction between two surfaces in contact. The improper selection of a lubricant can result in wasted energy due to heat loss and premature wear of parts. Lubricating oils are generally classified into two categories, Learn More>>
Hot-dip galvanizing (HDG) offers many advantages relative to other corrosion protection systems. HDG offers both barrier protection of the substrate and cathodic protection. No paint system can do that. Unlike paint, HDG is actually THICKER at edges and... Learn More>>
The primary purpose of a hydraulic fluid is to transmit power mechanically throughout a hydraulic power system. However, hydraulic fluids are also required to provide lubrication of contact surfaces within system components, sealing of equipment with tight clearanc Learn More>>
This is an introduction to cathodic protection for underground structures such as tanks and pipelines. It covers the two principal methods used to mitigate corrosion: the sacrificial anode and impressed current systems. Learn More>>
Overview Selecting the appropriate lubricant is a critical step in gear design. When properly selected and applied, gear lubricants reduce friction and wear, help to prevent corrosion, reduce operating noise, improve heat transfer and facilitate removal of abras Learn More>>
This course teaches the following specific knowledge and skills: Methods of steel member fabrication, Most common steel shapes used in bridge construction, Types and causes of steel deterioration, Factors that influence fatigue life, Protective systems for steel, Inspection procedures for steel, Properties of steel, Properties and types of other metals used for bridges: cast iron, wrought iron, and aluminum, Other causes of deterioration: temperature changes, chemical attack, moisture absorption Learn More>>
Overview The first use of a cathodic protection system dates back to 1825 when Sir Humphry Davy used malleable iron in a series of experiments to protect the copper clad ships of the Royal Navy. The iron served as a sacrificial anode, thus protecting the... Learn More>>
Overview Simply stated, a coating consists of a film-forming material dissolved in a solvent. The film-forming material is called a resin. When the resin contains pigments it is called a binder because it binds the pigment particles together and to the substrate Learn More>>
The understanding of the structure and properties of metals, stress mechanisms, failure modes and the characteristics determine their usefulness for a specific application. Often, materials are subject to variable forces (loads). The mechanical engineer... Learn More>>
