Export–import of high-tech products between NAFTA and EU countries is since years an important part of TTZH transatlantic activities. In July 2010 TTZH visited several points of US American South West as a part of our regular work and business development in North America. Some selected pictures made during this trip are demonstrating the virgin landscapes of Colorado and city view on skyscrapers in California.

February, 2010:
Prof. Dr.-Ing. Karl H. Spies (on the photo left) started his activities as TTZH tribology consultant in the beginning 2010. Prof. Spies studied Mechanical Engineering at University of Karlsruhe and then obtained his PhD title at the Chair of Machine Elements and Automotive Engineering under the supervision of Prof. Kollmann. Afterwards he entered the company Carl Freudenberg in Weinheim / Bergstrasse (www.freudenberg.de) and at first worked there as Head of Development. The next stations were supervision of the business units as a manager with the responsibility for 3 plants with 800 employees. After this he established R&D Department at Freudenberg Sealing and Vibration Technology, aiming to develop the fundamentals of sealing technology, new products and process engineering, and the testing methods as well. The next stations were with the central research and development of Freudenberg, build up of central advanced engineering for automotive technology and supervision of the central test technique for the tests of engines and vibration technology.

During the work as Head of R&D department Prof. Spies obtained a professorship for the subject “Sealing technology of elastomer materials” at the University of Kaiserslautern, Faculty of Mechanical Engneering. He performed these activities for more than 20 years. After 10 years professorship he received there a title of honorary professor.

During the professional activities he worked over 10 years in VDMA (www.vdma.org) in Research Association for Combustion Engines (FVV - www.fvv-net.de), as general coordinator of the planning group for tribology, fatigue strength, and materials and launched over 50 research projects.

January, 2010:
At the exhibition booth in Ostfildern during 17th International Colloquium Tribology “Solving Friction and Wear Problems” on 19–21 January 2010 TTZH presented new equipment for tests of greases under various special conditions. Technical presentations about this equipment and its specific aspects, applicable in automotive industry, aviation, defence, wind energy and more were made by Mr. Arno Simon “Development of a New Test Rig to Determine Starting and Running Torque of Lubricating Greases at Low Temperatures” and Mr. Peter Albers “Viscosity measurement at high pressures up to 14000 bar – further development of a quartz viscometer”.

July, 2009:
Mr. Vishal Khosla, senior applications and marketing eingineer of Center for Tribology, Inc. visited Europe with a goal of reporting to tribologists and materials scientists about the latest developments in mechanical nano+microanalysis of the surfaces and providing product range training to younger TTZH specialists, including some aspects of surface characterization under high temperatures.

Apart from experiences in UNMT techniques, his expertise includes a strong technical background in CMP techniques and tribological aspects of Chemical Mechanical Polishing being of importance in microtechnology and semiconductor industry.

January, 2009:
TTZH started the year with participation at 3D Days in Oldenburg on 28-29 January 2009. The outstanding techniques for 3D topography analysis demonstrated at TTZH booth, is made in Besançon in France, and it is very useful not only for standard measurements, but also for many unconventional applications, like architecture, archeology, criminal investigation technique and more. The visitors have got a possibility to see both laboratory instrument and NJ Portable, applicable for the field measurements.

The picture shows the moment of processing the results of surface measurements by Mrs. Anne Calvez of nanoJura, using the powerful software NJ nanoMap®.

November, 2008:
18^th Simrit Innovation Forum was organized in the Stadthalle Weinheim at 6th November 2008. In the technical presentations have been introduced the state-of-the-art developments of innovative products, materials and services.

TTZH experts participated in this forum. Dr. Michael Efron is with TTZH as a project manager. He obtained his PhD in agricultural machinery and presently he is putting a special attention to the high precision components of machines and seals for versatile applications in wind energy, steel industry, oil and gas industry, cars and tractors production, instrumentation etc. He is supervising the current projects in Europe and in Middle Asia.

April, 2008:
International Tribology Conference “Friction, Wear and Wear Protection” organized by German Society of Materials Science was hold on 09.04.-11.04.2008 in Aachen, Germany. The Conference was chaired by Prof. Kirsten Bobzin of Institute for Surface Engineering of RWTH Aachen and Prof. Alfons Fischer of Institute for Product Engineering of University Duisburg-Essen.

On the picture one can see the front entrance in Eurogress during the days of the Conference.

TTZH hosted at their booth the manufacturers of scientific equipment for tribotesting (www.cetr.com) and 3D surface analysis (www.nanojura.com). The moment seen on the picture demonstrates a consultation of a German professional in microtechnology with the Director of Sales of CETR, Inc. Mr. Jun Xiao (left).

January, 2008:
16^th International Colloquium Tribology “Lubricants, Materials and Lubrication Engineering” hold on January 15-17, 2008 in Stuttgart/Ostfildern, Germany. Since years the Colloquium is organized by Prof. Wilfried J. Bartz (www.tribo-lubri.de) and takes place at Technical Academy Esslingen.

TTZH and CETR contributed with two technical presentations.

On Technological Heredity of Some PVD Coated Triboelements, authored by Dr. Alexander Minewitsch, and
Effective Testing of Lubricating Oils, authored by Dr. Norm Gitis.

TTZH booth at the accompanying exhibition has been an attractive place for multiple tribology discussions of many professionals dealing with triboanalysis. The picture shows a moment of the meeting between one of the famous German tribologists Prof. Klaus Spiegel from Duesseldorf and Dr. Norm Gitis from Campbell, California. The implementation of UMT techniques for the testing of plain and journal bearings have been one of the important issues of their technical discussion.

September, 2007:
Just like in the past years the TTZH exhibited again this year at the Annual Meeting of German Tribology Society GfT in Goettingen from 24 till 26 September 2007. Mrs. Ulrike Quinn, the hostess of the stand, supplied the visitors with technical information regarding tribology products recommended by the TTZH, including testing equipment, precision balls for science and industry, pumps, tubing, levitator bearing kits, etc.

A technical presentation at the session “Tests, measurements, control” was given by Dr. Alexander Minewitsch. It focused on the problems of estimation friction coefficient and wear rate in reciprocating tests, scratch-adhesion, scratch-hardness, nanohardness and modulus of elasticity of thin PVD coatings.

March, 2007:
TTZH hosted President of Center for Tribology, Inc. Dr. Norm Gitis on 19 March 2007 in its Heidelberg office. Technical presentation was devoted to the UMT instrumentation for tribotests, nano-micro-macro characterization of materials, incl. nanoindentation, atomic force microscopy, analyses of surface and subsurface damages, surface profiling, etc.

It was followed up with intensive technical discussions and analyses of specific R&D and QC problems with the aim of formulating the tasks for configuration and design of new customized instrumentation.

Dr. Norm Gitis, President of Center for Tribology, Inc., Campbell, CA, USA is Fellow STLE and Chairman of STLE Tribotesting Technical Committee.
