Laser surface treatment for extender lifetime of parts for combustion engines, tools for sheetmetal working and small machine parts

Objective



Machine parts and tools subjected to cyclic, mechanical and/or thermal loads and which are operating under corrosive, erosive and/or aggressive conditions exhibit a restricted lifetime. These operational conditions cause wear and corrosion attack and lead to direct costs for repair and to indirect costs by stagnation of production. For some of these parts and tools laser surface treatment would be a way to a higher productivity. In contrast to the USA and Japan surface treatment with lasers is not yet established in Europe's industry. At present heat treatment with lasers has been practised on testpieces for a few types of materials and mostly on strait shapes, where start and end spots of the treatment were not of great importance. Some incidental tests on tools for sheetmetal bending learned that a practical method for finding the optimal parameters on a large variety of material/shape combinations is necessary. Problems have to be expected in obtaining a regular hardness pattern on the full treated surface of the test pieces, due to irregular surface properties (coating), heat absorption, as well as thermal conductivity. Moreover, the parameters will be highly dependent on the intensity distribution of the used laser beam. The objective of this project is to develop a production technology employing laser alloying, laser cladding and laser hardening for achieving extended lifetime of machine parts, tools for sheetmetal working and parts for combustion engines. A thorough investigation of process parameters will lead to a reliable surfacing process. Procedures for laser treatment of real 3D parts will be developed. The consortium comprises one research institute, one research department of a SME which is familiar with material laser treatments and two research departments of universities, a SME which is occupied with laser treatments of metal surfaces, seven manufacturers of tools, machine parts and engines (also SME's) and three large enterprises (manufacturers of engines, gearboxes and electronic equipment).
