It might not seem like scraping the top of a cold stick of butter with a knife could be a scientific test, but engineers say the process is very similar to the "scratch test," which is perhaps the ...

• Engineers can use hardness testing to verify the composition or heat-treatment history of materials. • Rockwell, Brinell, Vickers, and Shore are common hardness tests. Their use depends on the ...

Ceramic coatings are used in motorsports to protect against heat and wear. Image Credits: Marcin Krzyzaks/shutterstock.com Ceramic coatings are used in a wide variety of industrial and commercial ...

To investigate materials’ mechanical properties, nanoindentation and micro-compression tests are often used. These properties of materials are interrogated using either load or displacement control, ...

When designing metal parts, it's important to specify their hardness. However, many engineers have only a shaky understanding of what hardness actually is, or how it's measured. There are good reasons ...

Diamond has long been regarded as the practical and theoretical hardness champion and has found uses ranging from industrial abrasives to a girl’s best friend. Cubic boron nitride, a synthetic ...

The condition and physical properties of the work material have a direct influence on the machinability of a work material. The various conditions and characteristics described as "condition of work ...
