Tribological properties of Fe7Mo6-based-alloy lubricated with poly-alpha-olefin containing PN additive

Microstructure and tribological properties of Fe-Mo alloy-coated steel specimens prepared by low-pressure plasma spraying

“…The specific wear rates of the coated specimens and the ball specimens were then calculated using a surface profilometer and optical microscopy [2,3]. Then each worn surface of the coated specimens and the ball specimens was examined using a SEM with an EDS attachment.…”

“…It was found in our previous study that Fe 7 Mo 6 -based alloy specimens prepared by spark plasma sintering (SPS) [1] exhibited lower friction coefficients and lower specific wear rates than gray cast iron, Fe and Mo disk specimens when sliding against ASTM 52100 steel balls in poly-alpha-olefin (PAO) and a typical oil used in the sliding guideways of machine tools [2,3]. XPS analyses revealed that the low-friction coefficients of the Fe 7 Mo 6 -based alloys were due to the formation of low-friction MoO 3 films during the sliding tests [3]. Such oxide films are expected to be formed by adsorbing oxygen from the oil and air.…”

Preparation of graphene and its tribological properties based on deep eutectic solvent stripping method

“…Common lubricant additive zinc-diallkyldithiophosphate (ZDDP) can reduce wear and friction but contains environmentally hazardous sulfur and phosphorus [3] . Creating environmentally friendly lubricant additives with low phosphorus and low sulfur has consequently become a key initiative in lowering the energy consumption of automotive engines [4] .…”

Comparison of the effects of ionic liquid and anti‐wear additives on the tribological properties of Cr―Mo―N coatings

“…As a lubricant base stock, PAO is of significance, since it possesses low volatility, low pour point, excellent viscosity–temperature properties and good thermal stability and chemical stability. More importantly, the tribological properties of lubricant base oils, such as anti‐oxidant ability, corrosion resistance, friction‐reducing and anti‐wear abilities and extreme pressure properties, can be further improved by introducing suitable extreme pressure, anti‐wear and friction‐reducing additives . Ionic liquids as lubricants or as lubricant additives have been widely studied because of their excellent friction‐reducing and anti‐wear characteristics .…”
