摘要:
A coated metal article such as, e.g., a tool, which article comprises a body part comprising a substantially carbon-free precipitation-hardened iron-cobalt-molybdenum/tungsten-nitrogen alloy and carries a coating. The coating has been applied by a PVD method and/or a CVD method and comprises a substantially single-phase crystalline, cubic face-centered structure.

摘要:
The invention relates to a method for the production of tools for a chip-removing machining of metallic materials and to a tool with improved wear resistance and/or high toughness. The invention further provides an alloyed steel with a chemical composition comprising carbon, silicon, manganese, chromium, molybdenum, tungsten, vanadium, and cobalt as well as aluminum, nitrogen, and iron. The alloyed steel may be used to make tools to a hardness of greater than 66 HRC and increased chip-removing machining performance.
摘要:
A cold-forming steel article which comprises an alloy that comprises carbon, manganese, silicon, chromium, molybdenum, vanadium, tungsten and optionally, niobium in certain concentrations, as well as up to about 0.4 wt. % of accompanying elements, remainder iron and contaminants. The article is formed by atomization of a melt and hot isostatic pressing of the resultant powder. The article exhibits a hardness of at least about 60 HRC and a toughness in terms of impact strength of higher than about 50 J. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
