摘要 |
An ultra-hard and metallic construction comprises an ultra-hard component that is attached to a metallic component via a braze joint. The braze joint is interposed between the ultra-hard component and the metallic component, and comprises a first braze material bonded to a surface of the ultra-hard component. The braze joint includes an intervening layer in direct contact with the first braze material, and that is formed from a rigid material. The braze joint further comprises a second braze material that is interposed between the intervening layer and the metallic component, and that is different from the first braze material. |
