    Abstract: A method for additive manufacturing with multiple materials. First (48), second (50), and third (52) adjacent powder layers are delivered onto a working surface (54A) in respective first (73), second (74), and third (75) area shapes of adjacent final materials (30, 44, 45) in a given section plane of a component (20). The first powder may be a structural metal delivered in the sectional shape of an airfoil substrate (30). The second powder may be a bond coat material delivered in a sectional shape of a bond coat (45) on the substrate. The third powder may be a thermal barrier ceramic delivered in a section shape of the thermal barrier coating (44). A particular laser intensity (69A, 69B) is applied to each layer to melt or to sinter the layer. Integrated interfaces (57, 77, 80) may be formed between adjacent layers by gradient material overlap and/or interleaving projections.

    Abstract translation: 一种多种材料添加剂制造方法。 第一(48),第二(50)和第三(52)相邻粉末层在相邻最终材料的相应的第一(73),第二(74)和第三(75)区域形状中被输送到工作表面(54A) (30,44,45)在组件(20)的给定截面中。 第一粉末可以是以翼型基材(30)的截面形状输送的结构金属。 第二粉末可以是在衬底上以接合涂层(45)的截面形状递送的粘合涂层材料。 第三粉末可以是以隔热涂层(44)的截面形式输送的热障陶瓷。 将特定的激光强度(69A,69B)施加到每层以熔化或烧结该层。 集成接口(57,77,80)可以通过梯度材料重叠和/或交错突起在相邻层之间形成。
