The diversity of lubricating grease species, each with their own complexity and philosophy, raises the demand for the diversification of existing screening methods even in model testing. This article presents an overview of existing standard methods as well as application-oriented testing procedures, which can be used for evaluating friction, wear, and extreme pressure properties of lubricating greases in a model tribometer. For lubricant developers, the SRV® technology platform offers not only testing according to the established test methods and relevant standards, but also the possibility of testing new products in application-oriented load situations. The testing according to standards can be used as a screening test for the grease chemistry and the flow properties of the grease sample. However, it reflects the potential real-life operating conditions of a product in only a very limited way. This article will present test scenarios for such application-oriented friction and wear tests through a few selected examples:
Effect of wear particles on the lubricity of a lubricating grease
High temperature fretting behavior of industrial greases
Simplified examination of rolling/sliding friction of high performance greases
