Tribological Consulting And Lab Services

The materials testing lab at Nova Werke AG offers testing and consulting services both for internal research and development and external customers.

Tribology

Wear and friction measurement at Nova Swiss

At Nova laboratory we can conduct several tribological systems to investigate coatings and surface engineered materials subjected to friction and wear for their application 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 solve complex wear and friction problems related to coating solutions. Independent of what our customer requires; extending product’s life time, reducing downtime, or optimizing 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 “Deutsches 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 thousands of samples to screen and/or simulate a particular application.

Wear Testing 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. Here are some of our tribometers and testing set-ups:

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

Oscillatory vibration-friction wear "SRV"

2. Pin-On-Disk (POD) or Ball on Disk tribometer (ASTM G 99)

Standard test method for wear testing with a pin-on-disk apparatus.

2. PIN OR BALL ON DISK (PIN-ON-DISK, POD) (ASTM G 99)

3. Block-on-Ring under atmospheric conditions and elevated temperatures (ASTM G 77)

Standard test method for ranking the resistance of materials to sliding wear using block-on-ring wear test.

Block-on-Ring test under atmospheric conditions or high temperatures (bis 700°C) (ASTM G 77)

4. Solid particle erosion test (ASTM G 76), (high-temperature optional)

Standard test method for conducting erosion tests by solid particle impingement using gas jets.

Solids particle erosion test (ASTM G 76), (high-temperature option)

5. High pressure liquid (with/without solid particle) impingement erosion test (ASTM G 73 and 76)

A combination of the standard test method for liquid impingement erosion and the standard test method for conducting erosion tests by solid particle impingement.

High pressure liquid erosion (with or without solids) (ASTM G 73 and 76) combined/modified

6. Slurry abrasion test / Miller test (ASTM G 75)

Standard test method for determination of slurry abrasivity (miller number) and slurry abrasion response of materials (SAR number).

Determination of the grinding effect of slurry based on the Miller numbering system / Miller test (ASTM G 75)

7. Cavitation erosion vibratory tribometer (ASTM G 32)

Standard test method for cavitation erosion using vibratory apparatus.
