Fracture behaviour of an aluminide coating on a single crystal superalloy under tensile conditions
The fracture behaviour of an aluminide coating applied to the single crystal nickel based superalloy SRR99 under tensile conditions is reported. A set of tensile tests were carried out in order to determine the fracture strain of the coating at different temperatures. During testing the sample surface was periodically recorded by means of a video camera system. The analysis of the surface images allowed a local fracture strain to be estimated. The local strain state and the position at which cracks were initiated are described in terms of the substrate crystal orientation.
