 Wear and friction testing at Nova

 The Nova laboratory offers testing facilities and consulting services to meet internal research and development needs as well as to external customers. The laboratory conducts several tribological systems to investigate materials subjected to friction and wear (coatings and surface engineered materials) for their use in harsh environments, e.g. elevated temperature, high humidity, high loading stress and high speed. Our dedication to the highest levels of customer service and excellence helps us to resolve complex problems related to coating solutions, the wear and friction of major components used in the industry. Independent of what our customer requires, to extend product's life time, reduce downtime, or optimize the material performance and reliability. Our Tribology set-ups can be used according to several standardized procedures (mainly: ASTM “American Society for Testing and Materials”, DIN “Deutschen Institut für Normung”, and ISO “International Organization for Standardization), or we tailor our testing programs to meet our customers' individual needs, whether they regularly test just a few samples or need us to analyze hundreds of samples to screen and/or simulate a particular application.

Facilities

The Tribology laboratory is well equipped to cover a wide range of tribological systems to simulate industrial friction and wear problems at different scales. Some of our test set-ups are the following:

1. High frequency oscillating tribometer “SRV” (DIN 51834)

Standard test method for measuring the friction and wear properties of lubricating oils using the SRV test machine
