SURVEYS OF ABRASIVE WEAR-RESISTANCE WITH THE HELP OF SCRATCH-TESTS

Scratch-Tests under grooving conditions were carried out on four chrom ium alloy cast iron with different temperature treatments, two Hadfiel d-Steels, one ferritic-perlitic steel and one ferritic steel. The scra tching took place with a cone-shaped indenter under variation of the n ormal strength. The scratches were measured with the help of a laser m easuring device. After this it was possible to determine the deformed surface and the scratch energy density. With these results possibiliti es for abrasive wear resistance and for the use of parts made from the tested materials can be derived.
