Drilling fluids can be clay-based, oil-based, and polymer-based. Polymer drilling fluids reduce friction in the drill string. Polymer drilling fluids also prevent jamming of the drilling tool and perform an anti-corrosion function. Friction is one of the key characteristics of drilling equipment wear. Reducing friction reduces metal wear, which in turn

Tribological properties of ormosil coatings
Journal of Sol-Gel Science and Technology, 1996Transparent plastics are not scratch resistant. The damage leads to a loss of optical properties. Coatings prepared using either tetraethoxysilane or colloidal silica particles embedded in “glymo” is a way to avoid these disadvantages. Tribological experiments are carried out to better understand the surface modification due to a sliding friction.

Testing of Tribological Properties of ADI
2019This experimental work consists of testing of isothermally improved specimens for wear process without lubrication. In the first part investigated was tribological properties on tribometer pin on disc made produced from ADI. Tested was loss of length and loss of mass of pin for different increasing number of revolutions.

Tribological Properties of Glass‐Ceramics
Journal of the American Ceramic Society, 1984Tribological properties of five glass‐ceramics are reported. The materials were tested unlubricated against themselves. Testing was performed using a simulated inertial sample dynamometer. Sliding speeds were between 0.5 and 1.8 m /S with an applied load of 225 N. Average friction coefficients were in the range 0.07 to 0.5.

Tribological properties of a-C:H:Al coatings
2014Hydrogenated amorphous carbon (a-C:H) thin films are among the best coating solutions for the reduction of automotive fuel consumption because of its very good tribological properties. Friction losses are indeed the main source of energetic consumption in an automotive engine.

Tribological Properties of Rubberlike Materials
1983Friction is reggarded as a fundamental energy-dissipative mechanism1,2 as a result of which surface degradation and wear occur. In the case of rubberlike materials, such a mechanism exhibits distinct viscoelastic properties, and it is common to distinguish between adhesional and hysteresis friction.
