"friction layer" is correct and usable in written English.
You can use it in a sentence to describe a type of material that increases friction with another surface, such as "The rubber friction layer on the car tires increased traction on wet roads."
It partly covered the top surface of the friction layer.
This friction layer protected the bulk materials from serious degradation.
To increase damping capacity, a friction layer was inserted between the aluminium-composite interface.
"Generally, the higher you go, you lose what is called the friction layer," where friction with the surface of the earth itself slows the wind somewhat, Mr. Searles explained.
Several stable T S relationships are found below the friction layer and at the Fronts.
One interesting aspect observed is that the wearing out of copper fibres produces fine copper particles entering the friction layer, thus contributing to its compaction.
Carbon/epoxy composite aluminium hybrid structures with friction layers were used to increase structural damping.
It features adjustable size and number of friction layers to yield desired voltage and power density.
A pre-charge injected multilayer-linkage triboelectric nanogenerator (PMLL-TENG) with all its friction layers ganged, contacted and separated simultaneously, has been designed.
Wear products, namely the friction layers that formed on the mating surfaces of the pin materials, have been characterized to identify the main phenomena involved and influencing wear rate and friction coefficient.
Nanostructures fabricated through a simple method and prior-charge injection into the space between the surface of the friction layers and the electrodes were used to greatly enhance the property of triboelectric nanogenerator.
