Diamond bonded constructions comprise a body comprising a plurality of bonded together diamond grains with interstitial regions disposed between the grains that are substantially free of the catalyst material used to initially sinter the body. A metallic substrate is attached to the body, and a braze joint is interposed between the body and the substrate. The body is metallized to include a metallic material disposed along a substrate attachment surface in contact with the braze joint, wherein the metallic material is different from the braze joint material. The metallic material may exist within a region of the body extending fully or partially into the body, and/or may exist as a layer extending away from the substrate attachment surface. The body includes a working surface characterized by empty interstitial regions or by interstitial regions filled with an infiltrant material, wherein the infiltrant material is different from the metallizing material.

The invention relates to a method for producing a mould for casting metallic melts, in particular for casting titanium, titanium alloys or intermetallic titanium aluminides. Said method consists of the following steps: a contact layer is produced by applying a first slicker containing a first metal oxide powder as an essentially solid component to a moulded core, a first sanding layer is produced on the contact layer formed from the first slicker by sanding with a second metal oxide powder and the layer sequence formed from the contact layer and the first sanding layer is radiated with infrared light for a predetermined period of time. According to the invention, for speeding up the drying process, a first dry mass of the first slicker contains a hydraulic binder.
