New technology for powder metallurgy
Tecnalia leads EFFIPRO (Energy EFFIcient PROcess of Engineering Materials) project, which shows a new manufacturing process using powder metallurgy. The main aim of this project is to develop a significantly shorter PM process using a new concept of hybrid electrical current assisted sintering and hard materials with improved properties, thus resulting in a more energy efficient and cost effective process. In addition, higher performance metallic composites (based on hard metals) and engineering metallic materials will be processed. Tools for machining operations will be produced and two types of parts machined: one for the aerospace sector and the other for the automotive sector.
The objectives are: to implement a new PM process; to introduce new materials to the market and help industry overcome the technical difficulties in their manufacturing processes; to reduce manufacturing costs; to substitute the use of critical elements and hazardous materials for more safe and environmentally friendly ones; to reduce energy consumption by 20% during the process; to increase the competitiveness of the European hard metals industry; to complete a life-cycle analysis (LCA); to reduce by 25% the number of rejected parts; to reduce emissions of greenhouse gases by 40%; to reduce waste materials and increase the use of recycled materials by 10%; to substitute the use of hazardous elements (Co) by safe and environmentally friendly ones.
The use of this new technology will shorten the PM processing time and produce materials with enhanced properties (hardness, toughness and lifetime). In addition, significant reductions in energy consumption will be achieved during the sintering process. The cost of this new technology is expected to be in the same range or lower than the current industrial processes.
