Strain measurement of ultra-thick tungsten coating for nuclear fusion applications
Tungsten is one of the most promising materials to be used as protective coating layer of the steel frame parts of the divertor component in a fusion reactor. However, fabrication of thick tungsten coating on steel is notoriously difficult due to the significant mismatch of thermal expansion coefficient between tungsten and steel. Large thermal strain developed at the interface of the two materials often causes catastrophic coating detachment. We have successfully manufactured millimetre thick tungsten coatings directly on steel, employing a new “surface sculpture” technique for strain management. The proposed experiment aims to measure and quantify the strain within the tungsten/steel coating system, in order to understand the influence of surface sculptures on strain, and to provide generic insight into stress relief in dissimilar material systems.
