RVS in marine applications

The performance of RVS products in marine applications was tested in 2003 in a study conducted in Ukraine by Odessa National Marine University.

In the tests, laboratory experiments were carried out using AYe-5 and 77MT-1 friction testing machines to investigate the effect of adding an RVS compound to engine oil and aviation oil on the tribotechnical properties of friction pairs (steel–cast iron, steel–bronze, cast iron–cast iron).

Main test results

Based on the results, a recommendation was issued to use RVS products in sea-going and inland waterway vessels.
The tests demonstrated that the use of the RVS compound reduced friction coefficients and accelerated the running-in of machine friction components (shaft–rolling bearing, shaft–plain bearing, cylinder–piston ring).
The tests showed that once the wear rate stabilizes, adding an RVS compound at 0.2% of the oil volume reduces the coefficient of friction by 50–60% and lowers the temperature of the friction surfaces.
