in industrial applications, most materials are exposed to wear and friction because multiple conditions are used. however, the tribological properties of these materials can be improved with different techniques. one such technique that improves the frictional property of a surface is the use of self-lubricating coatings. in this study, multicomponent coatings of nominal composition cu-ni3al-mo...

The appeal of ceramics as structural dental materials is based on their light weight, high hardness values, chemical inertness, and anticipated unique tribological characteristics. A major goal of current ceramic research and development is to produce tough, strong ceramics that can provide reliable performance in dental applications. Quantifying microstructural parameters is important to devel...

The manufacturing of chemical vapour deposition (CVD) diamond coated shaft type cutting tools is demanding due to the complex design of the cutting edges and the cobalt content of the cemented carbide. The influencing parameters of substrate, pre-treatment and diamond film on the tool cutting performance are discussed. The optimised manufacturing route of CVD diamond coated thread milling drill...

Wepresent a fundamental study of the frictional performance of silicamicrospheres, either 4, 2, or 0.5 mm in diameter, on a silicon substrate. The tribological properties of these rolling systems were measured with a ball-on-flat tribometer at various loads. The frictional performance of the rolling systems is found to be highly dependent on load and sphere diameter. Rolling motion was confirme...
