Corrosion, friction and wear performance of diamond – like carbon (DLC) coatings
Metalurgija, 2016 The a - C:H:W, TiN/a - C:H:W and the CrN/a - C:H:W coatings were deposited on steel surface by physical vapour deposition methods and studied for corrosion and tribological properties, after elemental and structural analysis.

Tribological Properties of Ultrafine-palygorskite/Copper Composite Powder as Lubricant Additive
Cailiao gongcheng, 2018 The ultrafine-palygorskite/copper composites(ultrafine-P/Cu) were prepared by mechanical ball milling. The extreme pressure properties and the effect of load and speed on tribological properties of ultrafine-P/Cu powders, as 150N base oil additive, were ...

Advanced Science, EarlyView.This work overcomes the long‐standing challenge of hydrophilic modification of silicone rubber via a gradient polarity modification strategy. By constructing a hydrophilic interpenetrating network within cured SR, simultaneous surface‐to‐bulk modification is achieved while enabling monitoring through a Eu3+ complex fluorescent tracer.

Some aspects of oil lubricant additivation with ZnO nanoparticles [PDF]
, 2006 This is a study on the tribological behaviour of ZnO nanoparticles as an additive in a polyalphaolefin (PAO6) and on the influence of dispersing agents (OL100 and OL300). Antiwear and extreme pressure tests were run on two four-ball machines. Firstly, it

Synthesis of trimethylolpropane trioleate by using stannous oxalate catalyst
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study was conducted to synthesize trimethylolpropane trioleate (TMPTO) using a stannous oxalate catalyst and investigate the dependence of the esterification rate on reaction variables. The highest esterification rate of approximately 99% was achieved at a 2.75:1 oleic acid/trimethylolpropane, 1.5% catalyst amount, 180°C reaction ...

Multilayer chromium based coatings grown by atmospheric pressure direct liquid injection CVD [PDF]
, 2009 There is a great interest for multilayer hard coatings because they exhibit enhanced properties resulting from their nanostructuration. Such coatings are frequently constituted of carbide and nitride and are generally deposited under very low pressure by
