MATERIALS TECHNOLOGY: SINTEST
The project SINTEST (A rapid non-invasive instrument for determining the global and local porosity of parts manufactured by powder metallurgy) is a two-year Project financed by the European Commission within the scheme Research for the benefit of SMEs. In this project participate, 3 RTD performers: MFKK (Hungary), which is also the coordinator, the Grup Sistemes Sensors del Dept. de Ingeniería Electrónica from the UPC and Fundació CTM Centre Tecnològic; 3 technical SMEs: Gammatec (Germany), M-ING (Málaga-Spain) and Multitest (Bulgaria); and 4 PYMEs as end users: Sinterpres S.L: (Barberá del Vallés, Spain), Tozmetal (Turkey), TKI-Ferrit (Hungary) and Danalco (Denmark).
The main objective of the Project SINTEST is the development of a new three-dimensional inspection tool for pulvimetallurgical parts at an industrial scope based on the ultrasound technology. With the development of this technology the project seeks to obtain 3D density maps and also to detect cracks and defects in syntherized parts (final product). Therefore, this new ultrasound device is meant to be a non-invasive, rapid and efficient inspection tool of the quality of the final product which has to enable the companies in the pulvimetallurgical sector to provide quality final products within the safety levels comparable to the ones of fully dens materials. The results of SINTEST will be applicable mainly to the automotion and aeronautics sectors.
CTM´s role within the project focuses mainly on two tasks: “Characterisation of the quality of syntherized parts” and “Research about the corrosion developed on syntherized parts during the ultrasound inspection and measures for avoiding it”.
In the first task, CTM will determine the distribution of densities, the characterisation of defects and the critical values of porosity that can lead to the forming of cracks. It will also try to correlate the parameters of the compacting and syntherising processes with the forming of defective areas in a component.
In the second task, CTM will evaluate the level of corrosion reached by syntherized parts submerged during the inspection with the ultrasound device developed by UPC in different baths with water which contain different corrosion inhibitors.
