AIP Conference Proceedings Vol. 2051. P. 020180-1-020180-4Abstract: Abrasive wear is not favorable for Hadfield steel. The connection between the acoustic emission signal and the
formation of microcracks in the case of abrasive wear is evaluated during scratch tests. The amplitude increase of the
acoustic emission signal coincides with the formation of microcracks on the scratch surface in most cases. The acoustic
emission signal amplitude is greater the longer the crack length and the number of cracks. The direction of the indenter
motion has a greater influence on crack formation than the plane of scratch testing.
