Cel The main results that were obtained are: Steel camshafts - A completely new rotary swaged steel camshaft was developed. The achieved weight reduction is about 50% compared to cast iron camshafts. This reduction in weight should result in a reduction in the consumption of gasoline. - A completely new technique to alloy a three dimensional part like a camshaft using a two-stage process was developed. - Ledeburitic layers with a thickness of 0,4 mm after finish-grinding and a hardness of 650 +/- 50 HV were achieved. The processing time for one cam is approximately 75 s for the glue spraying and approximately 30 s for the laser alloying, using a laser power of 4 - 6,4 kW (CNC controlled). - The wear performance of the camshafts has to be proved in engine tests. Aluminium brake disks: - Production of a brake disk that was approximately 30 to 40% lighter than current cast iron brake disks. This reduction in weight should result in a reduction in the consumption of gasoline in a vehicle. - A new technique to alloy a brake disk using a two-stage process was developed. - Alloying of aluminium brake disks using CO2-laser radiation has been achieved, delivering alloyed layers of approx. 0.5 mm thickness and a hardness of 200 - 250 HV with a deformation less than 0.2 mm. - Concerning laser alloyed plasma sprayed disks, both wear and crack resistance are far better than those from plasma sprayed layers only, but at present remain lower than cast iron brake disks performances. Extruders: - High Mo-content layers for extruders were developed, containing 41-63 mass% molybdenum. The wear performance of the new laser cladded layers is up to 60% better than the plasma transferred arc (PTA) layers used at the moment in production. - The cladding technique for extruders was developed, especially the processing technique to clad tracks with a width of 12 mm and a thickness of 1 mm in one track.Aim of the proposed research is to develop economical, environment-friendly processes for the production of wear-resistant, high-performance layers on cost-effective, light substrates, employing laser radiation. The processes are to be developed on components subject to high levels of stress from the automobile industry (cam shafts, brake disks) and the plastics-processing industry (extruders). The process development work covers the following measures:1. Development of new processes via the combination of laser- beam processes with other thermal processes.2. Development of process control parameters to produce the surface layers on components of the materials:- unalloyed steel St52 - grey cast iron - aluminium alloys (e.g. AlSi9Cu)3. Characterisation of the developed surface layers and investigation of their operational properties.4. Assessment of the economic efficiency of the examined processes.In addition to the savings in costs due to weight reduction (e.g.ECU 45-90 million/year for brake disks), the increase in product quality resulting from these innovative techniques will also enable reductions in fuel consumption (reduction:140 million l/year in Europe) and CO2 emission. These represent essential criteria for improving the competitive capacity of the European automobile industry. The processes will also be suitable for application in other branches of industry (tool construction, aviation industry, turbine construction) and, in particular, in SMEs.
