文摘
- •
The film thickness of different greases was measured.
- •
The friction behaviour of different greases was investigated.
- •
Tests performed with fresh and artificially aged greases.
- •
Results analysed regarding the rheological and chemical changes caused by the aging.
- •
The film thickness increases and so did the friction behaviour of the aged greases.
