The current work presents the research results of abrasion wear and adhesive wear at rubbing and liquid friction of new austenitic, austenitic-ferritic ('duplex') cast steel and gray cast iron EN-GJL-250, spheroidal graphite iron EN-GJS-600-3, pearlitic with ledeburitic carbides and spheroidal graphite iron with ledeburitic carbides with a microstructure of the metal matrix: pearlitic, upper bainite, mixture of upper and lower bainite, martensitic with austenite, pearlitic-martensitic-bainitic-ausferritic obtained in the raw state. The wearing quality test was carried out on a specially designed and made bench. Resistance to abrasion wear was tested using sand paper P40. Resistance to adhesive wear was tested in interaction with steel C55 normalized, hardened and sulfonitrided. The liquid friction was obtained using CASTROL oil. It was stated that austenitic cast steel and 'duplex' are characterized by a similar value of abrasion wear and adhesive wear at rubbing friction. The smallest decrease in mass was shown by the cast steel in interaction with the sulfonitrided steel C55. Austenitic cast steel and 'duplex' in different combinations of friction pairs have a higher wear quality than gray cast iron EN-GJL-250 and spheroidal graphite iron EN-GJS-600-3. Austenitic cast steel and 'duplex' are characterized by a lower wearing quality than the spheroidal graphite iron with bainitic-martensitic microstructure. In the adhesive wear test using CASTROL oil the tested cast steels and cast irons showed a small mass decrease within the range of 1-2 mg.

International Conference in Konstancin-Jeziorna under auspicies of European Materials Research Society (E-MRS) has been held every two years. This year is our 10th jubilee meeting and 4th in Konstancin-Jeziorna. The previous Conferences were organized in Mądralin and Białowieża. The Conference series is dedicated to technology, research and application of modern ceramic materials. Promoter and organizer of the Conference was prof. Jerzy Ranachowski. This year the Conference is organized by Institute of Fundamental Technological Research Polish Academy of Sciences, Polish Ceramic Society and Warsaw University of Technology - Faculty of Chemistry, The E-MRS in Konstancin had been proceed from 5 June to 6 June 2007 and was important meeting for scientists from Belarus, Poland and Ukraine.

Zasadniczą cechą projektowania w duchu zrównoważonego rozwoju jest oszczędność zasobów naturalnych oraz odpowiedzialne nimi zarządzanie. Nowe technologie, zdolne do tworzenia nowych materiałów i zestawienia materiałów konwencjonalnych w nowy sposób, stawiają projektanta przed większą ilością wyborów niż kiedykolwiek wcześniej.
