Residual Stresses and Young's Moduli of Plasma Sprayed W+Cu Composites and FGMs Determined by In Situ Curvature Method

Original language description

In this work, application of the in-situ curvature method on plasma sprayed composite and graded coatings is presented. First, uniform composites of different W/Cu ratio, were sprayed by water stabilized plasma. By continuous monitoring of the curvatureof a flat specimen during spraying, the stress evolution throughout the entire history of coating formation was traced. By a simultaneous monitoring of curvature and temperature during post-deposition cooling, Young?s moduli of the coatings were determined. Second, a 5-layer stepwise functionally graded material (FGM) was sprayed. With the knowledge of each layer?s properties, the complex evolution of deposition, thermal and residual stresses in the FGM could be determined. The ability to determine thestresses and mechanical properties with a spatial resolution comparable to the thickness of one spray pass is demonstrated.
