Qualification of laser assisted surface technologies

Objective

Aim of the project is the development and transfer of laser surface techniques (LST) for improvement of the service life of tools and parts from different industrial sectors. The techniques under investigation are alloying, cladding and dispersing with powder additives using Co2 and Nd:YAG laser radiation. The main application fields are the development of wear and thermal resistant surface layers for forging and drawing dies and for machine parts (plastics processing technology, pressing tools for sand lime brick industry, metal sheet forming tools). The major research tasks are: Process and material development to produce wear and thermal resistant surface layers by one step laser alloying, dispersing and cladding with the blown powder technique Transfer of the results, obtained on simple geometries, to complex components Analysis and real tests of the operational properties of the laser treated components Comparison of the results of LST with those of conventional techniques Assessment of the potential for industrial application of the different techniques. Successful completion should yield cost reductions for tools in the European forging industry from 14 to 8.5 % which means cost savings of 220 million ECU per year. Increasing the service life of pressing tools for the sand lime brick industry by a factor 2 leads to a cost reduction of about 850.000 ECU per year only in a country like Germany. The different laser surface treatment processes can be applied directly by end users in various industrial sectors, especially by flexible SME's or can be offered by various SME laser job-shops.
