It is researched the method of boron determination by ICP-AES using microwave digestion method to decompose lubricating grease,the proper conditions of microwave digestion are settled down,the working parameters of ICP-AES are optimized, and the interference of co-existent elements is eliminated.
The results showed that the lamellar liquid crystal and the mixed system showed higher load carrying capacity relative to the commercial grease.
The derived kinetic equation for tribochemical grease degradation allows one to predict, with a practically acceptable accuracy, the service life of the friction unit and the advancement and chemism of tribochemical processes.
An increase of the valence angle in the CH2 groups of alkane molecules is detected when the crystallites in samples of ceresin grease melt on an aluminum substrate.
These chelates are volatile enough to be analysed by gas chromatography and the separation of Th and U complexes is performed at 170°C on a column filled with glassbeads coated with DC-QF 1 silicone grease.
We studied direct drug effects on rat abdominal vagus nerve using the grease-gap technique.
Thirty homologous series of functionalized perfluoropolyethers (FP) based on alkyl(aryl)ammonium salts were studied, by correlation analysis and statistical data processing, as inhibiting constituents of perfluoropolyether lubricating greases.
The potentialilities of the electrochemical protection and application of easily removable coatings, preservation oils, and greases doped with inhibitors and bactericides are considered.
Functional derivatives (FDs) of perfluoropolyethers are studied as corrosion inhibitors in (PFPE) greases based on the corresponding polyethers.
On the Use of the Quantity "Energy of Activation of Tribochemical Reactions of Greases" in the Rolling Friction Zone
The effect of friction parameters (contact stress and speed factor) on the total activation energy of the tribochemical conversions of greases in the rolling friction zone was simulated for singly packed rolling bearings.
Using the developed machine and the testing procedure, a lubricant grease Litol-24 was subjected to testing with additions of solid lubricants (graphite powder and MoS2) and organic dopes containing P, Cl, S, and O.
