摘要: The present invention relates to economic and environment-friendly slurries and their preparation, handling, and spray drying for the production of cemented carbide based hard metals. The slurry is ethanol-water based and contains metallic and metal carbide raw materials as well as polyethylene glycol (PEG) and a very low concentration of polyethylenimine (PEI). The concentration of PEI is 0.01-

摘要: Preparation, handling, and spray drying, in an economic and environmentally-friendly way, of slurries for the production of tungsten carbide based hard metal tools or components by the powder injection molding or extrusion route is disclosed. The slurry used is based on ethanol-water and contains metal carbide and metallic raw materials as well as stearic acid and a low concentration of polyethylenimine (PEI). The concentration of PEI is 0.01–1 wt % of the raw material weight. This combination results in low-viscous slurries, which require less use of ethanol, energy, manpower, and equipment time in their preparation, handling, and spray drying. The invention also relates to the powder obtained by using the method.

摘要: The present invention pertains to environment-friendly and economic preparation, handling, and spray drying of slurries for the production of titanium based carbonitride alloys. The slurry is based on ethanol and water and comprises raw materials for the end product as well as polyethylene glycol (PEG) and a low concentration of polyethylenimine (PEI). The concentration of PEI is from about 0.1 to about 0.7% of the raw material weight. Hereby, slurries with low viscosities are produced which require less use of ethanol and energy, as well as manpower and equipment time in their preparation, handling, and spray drying.

摘要: The present invention relates to cutting tool insert consisting of a tungsten carbide based hard metal substrate and a coating. The hard metal consists of about 4-15 wt-% binder phase with face centered cubic structure and a composition of 35-65 wt-% Fe and 35-65 wt-% Ni in addition to dissolved elements. As a result, inserts have been produced with at least as good performance in machining as conventional state-of-the-art inserts with Co-based binder phase. The insert can be applied in milling and turning of low and medium alloyed steels as well as stainless steels.
