Abstract: Systems and methods for real-time monitoring of electrical discharge events across a tribological contact are provided. The systems comprise a signal generator, a test device comprising a tribological contact, a reference device and a signal comparator. The systems recognize changes between states where electrical discharge across a tribological contact does or does not occur and produce distinct output signals for each state and, further, may maintain a count of how often such events occur.

Abstract: Provided are lubricant compositions and hydrocarbon fluids including one or more lubricant base stocks and an effective amount of one more zero SAP antiwear additives and/or corrosion inhibitor additives, wherein the one more antiwear and/or corrosion inhibitor additives include one or more functionalized polyolefins having one or more pyridazine moieties. Such compositions exhibit improved anti-wear, friction reduction and anti-corrosion properties.
