TRIBOLOGICAL CHARACTERISTICS OF MATERIALS USED FOR CARBON DISC HEART VALVE
Journal Title: Tribologia - Year 2014, Vol 255, Issue 3
Abstract
Carbon materials (glassy carbon or C/C composite) are used for the production of mechanical heart valves. Due to the extremely sensitive place of their implantation, they must meet numerous requirements: mechanical strength, chemical resistance, biotolerance, and a high resistance to tribological wear. The paper presents tribological and micromechanical research results of carbon materials at various stages of their production. In order to perform the analysis of tribological characteristics, the measurement methodology for the ball-on-disk tester (T-01) has been developed. This may allow a comparison of the results obtained with those received on the nanotribometers.
