The tribological behaviour of engineering plastics during sliding friction investigated with small-scale specimens

Friction Behavior of Engineering Polymers Treated by Atmospheric DBD Plasma

“…Friction and wear are very important mechanisms that should be taken into consideration as well in the moving machine elements failure studies [1]. Engineering polymers widely used in moving part constructions especially in microelectronic, mechatronics and generally in industrial applications, due to its zero corrosion, lubricating ability, high strength, stiffness, and good dimensional stability; in contrast, they often experience difficulties in gluing [2], and instability or overload during sliding [3].…”

Effect of shaft roughness and pressure on friction of polymer bearings in water

“…In another study Quaglini et al showed that an increased counter surface roughness influenced the material's frictional behavior depending on the polymers' elastic modulus [4] such that an increased counter surface roughness led to increased friction for soft polymers and decreased friction for polymers with high elastic modulus. Some other studies suggest the existence of an optimal surface roughness for minimal friction of different polymers [3,5]. The influence of contact pressure on tribological behavior of polymers has been extensively studied earlier in order to evaluate the limiting PV values for various polymeric materials in dry sliding conditions.…”

Tribological Comparison of Traditional and Advanced Firearm Coatings

“…However, in all the material combinations the thickness of the layer of transferred material decreases with increasing load because of greater compaction and the likelihood of loose material being detached from the surface. (48) Transfer rate is also dependent on the polymer's hardness, since the flexibility of the polymer chains increases for soft materials (reflected by a low elasticity modulus). However, in presence of oil, a transfer film is not observed.…”

“…It has been reported that thin transfer films are beneficial for friction at low speeds, intermediate temperatures, and smooth surfaces. (48) One of the traditional concepts for improvement in the friction and wear behavior of polymeric materials is to reduce their adhesion to the counterpart material and to enhance their hardness, stiffness, and compressive strength. This can be achieved quite successfully by using special fillers.…”

“…On rough surfaces an increased toughness influences the wear rate in the same trend irrespective of the applied load. (48) Microparticles and nanoparticles are being used to enhance the mechanical and tribological properties of polymers, this has been widely investigated in the past decade. Various kinds of microparticle filler, e.g.…”
