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

• 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.
