The decorative arts are arts or crafts whose object is the design and manufacture of objects that are both beautiful and functional.
Corrosion inhibitors are substances which when added in small concentrations to corrosive media decrease or prevent the reaction of the metal with the media.
Sources of radiation can be shielded with solid or liquid material, which absorbs the energy of the radiation.
Tinning is a process of using a soldering iron to melt solder around a stranded electrical wire. Tinning the tips of stranded wires holds the fine wires together and makes it easy to connect them to screw terminals or other connectors.
It's 100 times more durable than high-strength steel, making it the first alloy, or combination of metals , in the same class as diamond and sapphire, nature's most wear-resistant materials.
Wear is a natural process removing material from contact interfaces. For structural components this means a degradation of the function and eventually leads to failure.
Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
One way that surface roughness aids in adhesion is by increasing the total contact area between the paint and the adherend.
A sudden increase or decrease in conductivity in a body of water can indicate pollution.
