Our Institute has got a plenty of high-tech laboratories, with the help of our modern equipments we can solve almost every kind of problem in the field of metallurgy, casting and surface technologies.
Hydro- and Electrometallurgical Laboratory
Nowadays the hydrometallurgy gives us the answers for many long-standing problem.
Our laboratory stress on the following fields of the hydro-electrometallurgy:
- Extraction of ultra-high purity metals with the use of ion-exchange technologies
- Waste treatment with the use of hydrometallurgy,
- Handling and disposal of metal containing solutions
Moreover in the past few years with the contribution of the Hydro- and electrometallurgical laboratory numerous project had been fulfilled.
1. Present: Project “Baross”, Project” FORR-ÁSZ”, Cooperation with the ALCOA-Köfém Kft.
We have been participating in a complex project, which one’s aim is to find a new method to recover the precious tin content of different type of soldering waste materials. Firstly the project got its financial background from the so-called “Baross”-program, and from 2012 from the so-called “FORR-ÁSZ” project. As part of the research project we had found new methods to recover, purify and separte almost every part of the secondary raw material.
Furthermore nowadays we have renewed our connections with the Alco-Köfém Kft., and now we are succesfully cooperating with them in the field of aluminum slag treatment and in other related fields.
2. Metal extraction from galvanized ( Sn, Zn,etc.) waste materials
With the use of ion-exchange membrans we are able to recover and purify the metal content of several types of waste materials, with a very high purity. Currently we are working on a project which intends to apply the mentioned technology for the recovery of high-purity Zn.
3.Extraction of ultra-high purity metallic gallium
We are seeking for new technologies which ones are able to extract metallic gallium from alumina bases, but on the other hand we are working on new technologies connected to the Bayer-circle.
4. Extraction of precious and PGM metals from secondary raw materials
The prices of the precious and PGM metals are growing rapidly from day to day, more and more mines of them are running out of their supplies. Due to this, it is very important to find new methods and technologies to recover the metal content of the PCB and other microeletronic devices.
Main fields of interest:
In the broad fields of electroplating, hot dip galvanizing, surface treatments and surface technologies / engineering. We have extensive experience, expert knowledge base and partner network.
Within these main areas of expertise:
Methodological and technological developments on metallic (gold, silver, copper, tin, zinc, …) and other metal containing (like electroless nickel-phosphorus) and inorganic (passivating) thin surface films complying with the environment and health issues, as well as avoiding the use of any hazardous materials.
Applied research activities related to several deposition technological operations (hot dip galvanizing; chemical precipitation techniques; surface films formation via aqueous surface treatments and deposition /both chemical and electrochemical ones/). Studying the relevant unit processes, the surface conditions of the substrates subject to layer development, mechanisms of the various surface preparation alternatives, and through all this the improvement of bonding / coating adherence / coating compliance. Looking at novel surface preparation (cleaning) and surface pre-treatment options, for example, by using low-waste atmospheric plasma jet techniques, particularly to identify the practical new industrial applications.

Laboratory of Powder Metallurgy
1. Making and investigating special alumina materials
Investigation of the correlating effect of the sintering temperature and the density ( grain size, specific area, sintering properties) on the alumina production.
2. Making and investigating precipitatites (fine hydrates)
Searcing new methodes for the making of fine hydrates (different from the one which is used in the Bayer-circle).
3. Researches in the field of tungsram metallurgy
We are seeking after new methods in the field of tungsram powder metallurgy with the cooperation of the GE-Hungary Rt.

We can work out different types of smelting experiment with the use of our furnaces. We are able to produce special kind of alloys ( even prototype alloys). On the other hand the products can be analyzed by many of our modern material testing machines.
Technical properties and investigation opportunities of the laboratory:
• resistance heating furnaces: capable to smelt and cast any kind of aluminum based alloy from 4 to 100 kg
• induction furnaces: capable to smelt steel, iron, copper (from 20 to 100 kg )
• induction furnaces with vacumm: capable to smelt iron, copper, aluminum alloys (from 1 to 4 kg )
Modern analytical machines:
• GD-OES Profiler 2
• LECO TC500 gas analysator machine
• LECO CS244 element analysator machine (especially for C and S)
• Varian SpektrAA-300 atomabsorption spectrofotometer
In addition, we are able to cast the molten metal into sand forms or into iron moulds with the use of laddles (from 3 to 25 kg). The forging of the metals are solved.
Sand and Grain Analysis Laboratory
The Sand and Grain Analysis Laboratory is unique in Hungary for the examination of foundry sands and moulding materials. Green-sand, hot-box and cold-box core sand mixture properties can be analyzed in room and extended temperature. In case of different forming and core making technologies the laboratory can fulfill the requirements of industrial partners, such as gas evolution, deformation and strengths properties. By the help of the devices the laboratory is able to develop environment-friendly technologies, so called clean technologies and zero-emission procedures.
Foundry Simulation Laboratory
Foundry simulation for education, research and development is applied by the Department since 1991. Special scientific softwares are used for foundry research and development such as SIMTEC/WinCast software from the company RWP GmbH, NovaFlow&Solid software from the company NOVACAST AB and an adaptive software environment called Flow3D from the company Flow Science.
Computer simulation is a modern tool for casting developers, manufacturers and customers and also very important for university students for the up-to-date knowledge. By the help of a simulation software filling, solidification, cooling and residual stresses can be examined in case of different technologies (gravity, die, HPDC, LPDC..). Casting parameters can be calculated, controlled and developed casting dies can be configured, complex product- and technology development can be achieved.

Foundry Technology Laboratory
In the Laboratory aluminum, copper, cast iron and steel alloys can be melted and properties can be detected during solidification. Mechanical properties, microstructure analysis, melt treatment and solidification curve experiments can be carried out.
The IDRA OL-160 cold chamber high pressure die casting machine is equipped with shot analysis system, spraying robotics, vacuum system and die tempering system. By the help of the attached Semi-solid part semisolid experimental castings can be carried out and by the help of the technological parameter modification the plastic behavior of the alloys can be increased. Casting defect analysis and elimination proposals for industrial partners are also fulfilled.
