Characterization of lubricated bearing surfaces operated under high loads [PDF]

open access: yes
The composition and surface profiles of M-50 steel surfaces were measured after operation at high loads in a bearing contact simulator. An ester lubricant (trimethyolpropane triheptanoate) was used with and without various additives.

Effect of Friction on Preparation of NdFeB Nickel Coating by Jet Electrodeposition

open access: yesInternational Journal of Electrochemical Science, 2018
Sintered neodymium (NdFeB) magnets are highly vulnerable to corrosion. To address this problem, flexible friction-assisted jet electrodeposition is applied. This technique can effectively and quickly prepare protective Ni coating on NdFeB magnets.

Application of hydrophobic fluorinated silicon oxide nanoparticle coating on electrodynamic screen (EDS) films for enhancing self-cleaning function of solar collectors [PDF]

open access: yes, 2020
Optical surfaces, which are exposed to outdoor environmental conditions, are susceptible to dust deposition. Sunlight incident on the surface of photovoltaic (PV) modules is attenuated by the dust layer accumulation on the front surface of the modules ...

Anodic-modified anticorrosive coatings

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
Steel machine parts are exposed to electrochemical corrosion. This applies to many environments including atmosphere, soil, water, and even various fertilizers. High-carbon steel and low-alloyed steel are not stable (in terms of thermo-dynamics), do not feature effective passivation, and even the corrosion products do not form a stable protection layer.
