CHECK OF RESIDUAL OPERATION LIFE VIA HARDNESS MEASUREMENT BY MOBILE ULTRASONIC CONTACT IMPEDANCE (UCI) HARDNESS TESTERS

Michal Junek, Jiří Janovec

Abstract

The paper deals with the hardness measurement by mobile UCI hardness testers as a mean of determining the residual operation life of the power unit components. It aims to answer questions regarding the level of dependence of UCI hardness on Young´s modulus of creep-resistant steels and determining the conditions of UCI hardness tester calibration. The experimental part describes comparative measurements of hardness values obtained using stationary hardness tester and UCI hardness tester.
