Abstract
Sintered and unsintered articles of refractory metal carbide and cementing metal having thicknesses greater than those obtainable by tape casting a slurry of ingredients onto a substrate, and having a cross section of substantially uniform appearance, are described, as well as a laminating method for producing such articles, the method comprising; (1) pressing the top surface of one or more unsintered flexible tape cast sheets against a smooth rigid surface to achieve a top surface smoothness comparable to the bottom surface smoothness achieved by tape casting, and (2) forming a laminate of at least 3 unsintered flexible tape cast layers by bringing the respective smooth surfaces of the layers into mutual contact and pressing the layers together to achieve bonding.
