SUPERALLOY MATERIAL DEPOSITION WITH INTERLAYER MATERIAL REMOVAL |
摘要 |
A method of depositing a multi-layer cladding (40) of superalloy material and an apparatus so formed. A first layer of material (20) is deposited on a substrate (22) such as by laser cladding of superalloy powder (54). The deposited material includes a directionally solidified region (24) and a topmost equiaxed region (26). The topmost region is removed such as by grinding to expose a flat surface (28) of directionally solidified material. A second layer of material (32) deposited onto the exposed flat surface will again have a directionally solidified region (34) and a topmost equiaxed region (36). The process is repeated until a desired thickness of cladding material is achieved, the multi-layer cladding having no equiaxed material between its layers throughout its thickness. |
