Abstract

The paper presents the method of forming TiO₂ coatings on 100Cr6 steel using the ALD method and assessing the properties of the obtained coatings. The coatings were assessed in terms of surface morphology, chemical composition, contact angle and tribological properties. The performed tribological tests show that TiO₂ coatings are characterized by lower resistance to motion. During measuring the geometric structure of surfaces on samples with TiO₂ coating, smaller wear traces were recorded than for 100Cr6 steel. The obtained values of the contact angles prove that the 100Cr6 steel coated with TiO2 is more hydrophobic than the uncoated 100Cr6 steel. TiO₂ coatings can be used in low-loaded tribological systems and as barrier coatings.
