Abstract
The capability of plasma spraying for producing near net shape, free-standing components of metallic, ceramic and layered composites with alternate ceramic and metallic layer systems was studied. A simple and efficient mold mandrel with attachments to release the sprayed component was designed and machined. The plasma spraying was carried out, with powders of nickel and zirconia–8 wt.% yttria to form shapes such as nozzles, cones and cylinders. The plasma spray parameters and the mold mandrel operation were standardized by trial and error to produce the near net shapes. The microstructure, fracture morphology and microhardness of the sprayed components were studied. The study showed that the shapes constituting metallic, ceramic and layered composites with alternate layers of ceramic and metallic materials could be successfully formed by plasma spraying.
