When attempting to cast sharp corners, the wetting behavior of the liquid metal will greatly affect the extent to which the corner will be filled. The contact angle, surface roughness, and applied pressure can alter the wetting behavior of the liquid metal. Wetting experiments were performed on substrates with angled channels. By varying the head height and particle size of the face coat, the effects of applied pressure and surface roughness on the penetration and final shape of the metal in the corner were investigated. The results of the experimental work were compared to predictions made by a previously created analytical model. The microstructure of the metal which penetrated the channels was analyzed. The results from these experiments will help improve the casting of sharp corners, allowing for more intricate turbine blade designs.
