Pulsed laser deposition a new technique for coating sheet materials and 3d industrial components at low temperatures

Pulsed laser deposition (pld) is a well-established laboratory coating technology. Up to now pld has not become a standard industrial coating technique. The aim of this project is to optimise the suitability of pld for industrial applications.

Thin film technology plays an important role in many technological areas, e.g. electronics, sensorics, optics, data storage, decorative or tribological applications. Pulsed Laser Deposition (PLD) is a Physical Vapour Deposition (PVD) coating technique for the production of thin films. A huge variety of PVD processes are applied today in thin film technology, e.g. thermal evaporation, arc ion plating, magnetron sputtering, thermionic arc deposition, and anodic arc deposition. The selection of a coating technique strongly depends on the application, normally the process with the most appropriate combination of features is used. In principle, PLD is a young coating technique despite the fact that the first experiments date back to the early 1960s. However, up to now PLD has not become a standard industrial coating technique despite its outstanding process features. The lack of PLD coating systems, which fulfil the requirements for industrial applications, is considered as one of the main obstacles to a breakthrough of the PLD technique. AIMS AND PROBLEM SOLVING In order to advance PLD to become suitable for industrial applications, a computer controlled PLD coating system has been developed and built-up at the LASER CENTER LEOBEN (AUSTRIA) and a similar system is under construction at the INSTITUTE OF OPTOELECTRONICS (POLAND). The next activities necessary are the up-scaling of the deposition process and the development and characterisation of new coatings, including the evaluation of these coatings in practical applications. Therefore the aims of this project are: 1) To optimise PLD for the deposition of coatings on differently sized parts ranging from planar sheet material (2-D) to three-dimensional parts (3-D) such as tools, precision components with non-planar surfaces or even cavities or parts made of temperature sensitive materials. 2) To develop new functional films with a tailored structure, e.g. tribological and corrosion protection coatings, functional coatings for electronic, optical and sensoric purposes and adhesive layers. 3) To open up new fields of applications for PLD and to establish coatings deposited by employing this process for the design and production of new and innovative products. 4) To build up a network in order to intensify the national and international cooperation between research institutes and industrial companies working in the field of laser assisted thin film technology and companies requiring functional coatings. INNOVATION 1) Fabrication of new generation coatings with tailored structures and properties by employing modern laser technology. 2) The deposited materials as well as the type of substrates are nearly unlimited. Deposition (with or without heating) of the substrates of metallic and non-metallic mono- or multi-layers with nano-crystalline or amorphous film structure and excellent adhesion. REQUIREMENTS * Pulsed Excimer and Nd:YAG laser systems * Vacuum components * Target and substrate rotation 4-D system * Optical components for laser beam guiding systems * INNOVATIVE PRODUCTS AND COMPONENTS DEMANDING FUNCTIONAL SURFACES. PHASES OF THE PROJECT Phase 1) Extensive test series have to be performed for process optimisation by systematically varying the process parameters. The evaporation experiments will be carried out by employing different types of pulsed laser sources. Furthermore it is planned to realise a hybrid deposition process by combining PLD with other PVD methods. In order to achieve an advanced understanding of the processes taking place during PLD, plasma diagnostic investigations will be performed. Phase 2) PLD will be used for the development and deposition of mono- and multi-layer coatings with tailored structure based on metals, oxides, nitrides and carbides. The coatings deposited will we characterised by employing scanning electron microscopy (SEM), transmission electron microscopy (TEM), secondary ion mass spectroscopy (SIMS), X-ray photoelectron spectroscopy (XPS), spectroscopic ellipsometry and X-ray diffraction (XRD). In order to characterise the mechanical properties of the coatings, microhardness measurements and tribological investigations will be carried out. Phase 3) Sample coatings onto industrial components and field-tests will be employed to open up new fields of applications for PLD. This requires the building up of a network between research institutes working in the fields of PLD and film characterisation and companies demanding functional coatings. These networking activities supported by EULASNET will be initiated by organising an international workshop. Keywords: thin film technology, Pulsed Laser Deposition (PLD), surface technology.
