..., owing to the presence of brittle phases or porosity in the deposits or inadequate adhesion between deposits and substrates ( Ref 22 , 23 ). In contrast, Ni-Cr-Si-B alloys, plasma sprayed and then flame remelted, are used to repair cavitation damage in hydroturbines in China ( Ref 24 ). Laboratory tests...

..., elimination of these inclusions during casting leads to an improvement of RCF life and thereby bearing life. Vacuum induction melting, vacuum arc remelting, electroslag remelting, and combinations of these processes are commonly used to produce bearings for demanding applications. Vacuum Induction Melting...

... deposition, and thermal spraying (TS). It provides a background to RCF in bearing steels in order to develop an understanding of failure modes in overlay coatings. The article describes the underpinning failure mechanisms of TiN and diamond-like carbon coatings. It presents an insight into the design...

... imperfections may be tolerable and how the other may be root-cause defects in service failures. The article explains the effects of joint design on weldment integrity. It outlines the origins of failure associated with the inherent discontinuity of welds and the imperfections that might be introduced from arc...

... and continued down the shell. Drain grooves had been arc gouged at the nozzle sites, and examination of the fracture surface at the grooves revealed short, flat segments of fracture area indicative of preexisting cracks. These features were consistent with crack indications found during magnetic-particle...
