AbstractMechanical and tribological properties of soft magnetic thin films with high permeability and low coercivity are very important for the application of these films in high-density recording heads. This paper reports our experimental observations on these important properties of FeTaN thin film head materials. Hardness(H) and Young’s modulus(E) for FeTaN sputtered films were determined by nanoindentation. Wear resistance of these films against commercial magnetic tapes was measured with a sphere-on-flat wear tester. The experimental results indicate that the FeTa films can be hardened when nitrogen is introduced. It was found in this study that the thermal stability of the mechanical properties such as hardness of thin films containing nitrogen is better than that of the film without nitrogen. However, our experiments also revealed that the wear resistance of FeTaN films decreases when the concentration of nitrogen increases and the hardness of the worn surface at a wear scar is lower than that of the unworn surface.

Purpose: The purpose of this article is to characterize and compare the structure, mechanical and tribological properties of low friction DLC and TiC thin films deposited on the austenitic steel X6CrNiMoTi17-12-2 substrate. Design/methodology/approach: In the research, the samples of the DLC and TiC thin films with transition hard AlCrN interlayer deposited by magnetron sputtering and PACVD technology respectively were used. Observations of topography were made using a scanning electron microscope (SEM), and the atomic force microscope (AFM). The structure of samples was performed using a Raman microscope. The microhardness tests of thin films were made by Oliver & Phare method. Findings: Studies confirmed that the combination of research SEM and AFM provide crucial information on the structure and topography of the samples. It was possible to obtain information about the topography parameters and allow for the assessment of morphology and quality of the tested coatings. Study of the structure using Raman spectroscopy revealed the band corresponding to the DLC and TiC thin films. Practical implications: The current application areas for low friction thin films are constantly growing, and the intensive development of techniques requires the use of new technologies what leads to the production of the specific surface layer and a thorough examination. Originality/value: Growing area of low friction coatings with specific properties requires the use of specialized tools aimed at assessing the topography and structures which are responsible for tribological properties.

Mechanical And Tribological Properties

Polydimethylsiloxane (PDMS), a silicone-based elastomeric polymer, is generally cured by applying heat to a mixture of a PDMS base and crosslinking agent, and its material properties differ according to the mixing ratio and heating conditions. In this study, we analyzed the effects of different curing processes on the various properties of PDMS thin films prepared by mixing a PDMS solution comprising a PDMS base and a crosslinking agent in a ratio of 10:1. The PDMS thin films were cured using three heat transfer methods: convection heat transfer using an oven, conduction heat transfer using a hotplate, and conduction heat transfer using an ultrasonic device that generates heat internally from ultrasonic vibrations. The physical, chemical, mechanical, and tribological properties of the PDMS thin films were assessed after curing. The polymer chains in the PDMS thin films varied according to the heat transfer method, which resulted in changes in the mechanical and tribological properties. The ultrasonicated PDMS thin film exhibited the highest crystallinity, and hence, the best mechanical, friction, and wear properties.
