Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Advanced Ceramics are being extensively used in the defense and aerospace industries. As the production of critical ceramic components require a high degree of engineering expertise and manufacturing ...

The performance, reliability and longevity of machined parts often depend on the physical characteristics of their functional surfaces. However, legacy surface roughness parameters, such as R a, are ...

Accurate dimensional tolerance and highly refined surface finishes are critical to the function of an orthopedic implant. There is a wealth of technical data available regarding the tribology of the ...

The surface finish achieved by a machining process determines how well a surface performs its given function. Surface inspection compares the specified nominal surface and real surface to find the ...

The concept of measuring surface roughness originated nearly a century ago as a means to prevent uncertainty and disputes between manufacturers and buyers. Now, it has become a common identifier used ...

Numerous oil and grease-lubricated bearing designs rely on adequate lubricant film thickness for smooth and trouble-free operation. Engineers must check that films are sufficiently thick so asperities ...
