Abstract

Slovenian industry has been reaching high quality in production of special mechanical parts and tooling for large series industrial production. There are numerous companies reaching this level by their skilled personnel mastering latest technology and state-of-the-art machining equipment. Such companies need to continuously invest in product improvement and development to maintain their important strategic position. In this industrial sector the development essentially represents better price performance, reliability, and quality of the product. This is often achieved by implementing materials having higher resistance to service loading of the component. Innovative approach to such problems include development of composite materials with spatially variable properties. This can be achieved by deposition of special-property materials to required areas of the components using high performance laser equipment (HPL). A HPL recently acquired by TKC research group offers great advantage to such innovative development in this industrial sector. In the initial stage of the project the innovative laser cladding technology and surface alloying is developed for hot-work industrial tooling. Basic research is performed on specially prepared samples. The performance of the clad layer is determined by its mechanical properties, such as hardness, toughness, and ductility, metallurgical properties, such as chemical composition and microstructure, as well as the tested thermal fatigue and wear resistance. The characteristics of heat affected zone in terms of mechanical and metallurgical properties is also determined. The focus of the project, however is on application of the technology on the industrial tooling and monitoring of its performance in service. Increasing needs for such development in Slovenian industry are demonstrated by a number of companies supporting this project. The TKC R&D team in collaboration with the Faculty of matirials and technology has the required experience and references on industrial projects to carry out such research.
