Sozopol Resort House of the Technical University,

Lazuren bryag St. № 7, Sozopol – The New Town, Bulgaria

Sozopol, Black Sea Coast, Bulgaria

Sozòpol (Bulgarian: Созопол, Greek: Sozopolis / Σωζόπολις) is an ancient seaside town located 35 km south of Burgas on the southern Bulgarian Black Sea Coast. Today it is one of the major seaside resorts in the country, known also for the Apollonia art and film festival (which takes place in early

September) that is named after one of the town's ancient names.

Welcome!

The Technical University of Sofia is the largest educational and scientific complex in Bulgaria in the field of

technical and applied science with an institutional accreditation grade of 9.5 (on the scale of 10) for the

period 2012 – 2018.

The University structure includes 14 faculties in Sofia, three departments, a Center of Information

Resources, a Library and Information Center, a Center for international meetings, a Center for Continuous

Education, a Center for Educational and Innovative Projects, a University Science and Research Complex for

innovations and knowledge transfer in the field of micro and nano- technologies and materials, energy

efficiency and virtual engineering, Post graduate schools, Scientific and Research Sector, small enterprises, a

branch in the city of Plovdiv with two faculties, a Faculty of Engineering and Pedagogy and a College in the

town of Sliven, a School for power engineering and electronics and two high schools – School of Electronic

Systems Technologies in Sofia and a Vocational School for Computer Technologies and Systems in the town

of Pravetz.

The Faculty of Industrial Technology (FIT) prepares specialists in the field of engineering and technology.

Ever since the first academic year in 1945/1946 the Faculty has trained thousands of engineers and has

always been a leading national center in the field of scientific research and applied activities. One of the

Laboratories in FIT is the Scientific & Production Laboratory “Tribology”.

Scientific and Production Laboratory “Tribology” –

40 years National Tribology Centre

_____________________________________

The scientific and production Laboratory “Tribology” is headed by Assoc. Prof. Dr Mara

Kandeva. The Laboratory “Tribology” was founded at the Technical University Sofia in 1974 by

Prof. DSc N. Manolov, and acts as National Tribology Centre in Bulgaria. It is the starting place

for feeding the National WEB in the tribospace, which is a contact network of

researchers/educators, customers and producers, and their achievements in the field of tribology and

tribotechnologies. Information about researchers, production companies and consumers of

tribological problems, tribomaterials, triboelements and tribotechnologies is rendered

systematically, aiming harmonization and improvement of effectiveness of the tribological services.

In sight are problems related to the management of friction, wear, lubrication, hermeticity,

serviceability and reliability of tribotechnical elements and systems in their operation and

maintenance.

6

The latest tribotechnologies developed in the Laboratory “Tribology” at the Technical University –

Sofia are tribotechnologies for application of wear-resistant gas-flame and ultrasonic powder

coatings in collaboration with the Belgian company “GMA-Technologies. Another tribotechnology

actual for Bulgaria and the region is a tribotechnology for qualification and regeneration of air

filters in motorcar and truck transportation. The method and technology are patent of the

Laboratory “Tribology”, Sofia.

Lubricants, additives and surface coatings are the thoroughly developed topics of the latest years.

The Laboratory for Tribology, with the support of the Society of Bulgarian Tribologists,

organizes the annual International Conferences on Tribology BULTRIB.
