Nanotribological, nanomechanical and interfacial characterization of atomic layer deposited TiO2 on a silicon substrate

2015

Abstract For every coating it is critical that the coatings are sufficiently durable to withstand practical applications and that the films adhere well enough to the substrate. In this paper the nanotribological, nanomechanical and interfacial properties of 15–100 nm thick atomic layer deposited (ALD) TiO 2 coatings deposited at 110–300 °C were studied using a novel combination of nanoscratch and scanning nanowear testing. Thin film wear increased linearly with increasing scanning nanowear load. The film deposited at 300 °C was up to 58±11 %-points more wear-resistant compared to the films deposited at lower temperatures due to higher hardness and crystallinity of the film. Amorphous/nanocr…
