PROPERTIES of Al2O3 CERAMIC COATINGS APPLIED BY ALD
METHOD ON 100Cr6 STEEL
The purpose of the paper was to assess the morphology, chemical composition, geometric surface structure
and contact angle, as well as to analyse the tribological properties of Al2O3 coatings deposited on 100Cr6 steel
using the technique of atomic layers ALD. Al2O3 coatings were selected due to their tribological properties,
adhesion to the substrate and hardness. Tribological tests were performed in a reciprocating motion in a ballon-
disc combination, with a counter-specimen of 100Cr6 steel, under the conditions of technically dry
friction. Surface morphology was observed under a scanning microscope, and an EDS analyser enabled the
performance of an analysis of the chemical composition of the samples. Wetting of the surface of the Al2O3
coating was determined by means of an optical strain gauge. The geometric surface structure before and after
the tribological tests was analysed by means of a confocal microscope with an interferometric mode. The tests
proved that during technically dry friction, the average coefficient of friction for the Al2O3 coating is lower
by approximately 30% than for 100Cr6 steel. The tested coatings are characterised by hydrophobicity.
