摘要： The invention relates to the field of material sciences and concerns a metal-ceramic composite with good adhesion, as can be used for example for forming tools or cutting tools. The object of the present invention is to provide a metal-ceramic composite with good adhesion which has a solid and durable bond between the ceramic and the metal. The object is achieved by a metal-ceramic composite with good adhesion comprising a metal component and a ceramic component which are joined together by material connection or material connection and frictional connection, wherein silicon, beryllium, titanium, chromium, nickel, manganese, hafnium, vanadium, zirconium, aluminium and/or their organic compounds are present in the region of the connecting surfaces and wherein the components have been made into a composite and together sintered as a green body. The object is also achieved by a method in which at least one metal component and one ceramic component are joined as an overall green body and together subjected to a temperature treatment, at least for the sintering of the ceramic components.

摘要： The invention relates to the field of ceramics and to composite shaped bodies that can be used, for example, for chip removing tools. The aim of the invention is to provide composite shaped bodies that have a free structure on their top surface and delimiting surface and that can be produced in series. Said aim is achieved in that the ceramic and/or power-metallurgical composite shaped bodies are made of a green sheet and an injection moulded body. Said aim is further achieved, according to the invention, in that a green sheet is incorporated into or applied to a mould, subsequently, at least one ceramic and/or powder-metallurgical injection moulding mass is applied to and/or placed on and/or incorporated on and/or in the mould by means of injection moulding, and subsequently, the mould having one or several parts is removed and/or the one or multi-part composite shaped bodies are removed from the mould. The steps according to the invention can be repeated one or several times.

摘要： The invention relates to a glow plug and methods for the production thereof. According to the invention, said glow plug is made from an electrically conducting and an electrically nonconducting element, sintered composite ceramic material being used for the production thereof. The disclosed glow plugs can preferably be used for fuel-operated auxiliary heaters of motor vehicles. The aim of the invention is to be able to produce said glow plugs in an inexpensive and flexible manner while providing the same with a longer service life and greater resistance to oxidation. Said aim is achieved by surrounding two opposite sides of the conducting element with the electrically nonconducting element while providing the conducting element with an expanded cross-section in the distal area, the ratio of the expanded cross-section to the cross-section of the electrically conducting element ranging between 2.5 and 5 to 1. Sixty to 85 percent of the surface of the proximal heating area of the electrically conducting element, which has a reduced cross-section, are covered by the material of the electrically nonconducting element.

摘要： The invention relates to a method for producing ceramic and/or metal components, in which a supporting structure which encloses at least one free space is formed using a polymer, and in which at least one free space is filled at least in a predefinable region with a plastically deformable or liquid mixture of at least one metal powder or ceramic powder and at least one organic binder. The mixture bears at least partially against the wall of the supporting structure. Then, during a first heat treatment, the mixture is transformed into a state having sufficient rigidity to maintain the geometric shape thereof and a temperature is maintained at which the polymer forming the supporting structure remains shape-stable. Then, during a second heat treatment, the temperature is increased and thereby the polymer forming the supporting structure is completely disintegrated and the metal powder and/or ceramic powder is sintered.

摘要： The invention relates to the field of ceramics, more particularly a light-weight green compact and a molded article which is used for manufacturing vehicles, for example, as well as a method for the production thereof. The aim of the invention is to design a light-weight green compact and a molded article which has high mechanical strength and an adjustable pore structure. Said aim is achieved by a light-weight green compact comprising an at least highly porous structure of webs which are three-dimensionally interconnected, are entirely made of ceramic particles and/or metal particles, and have the solidified structures of a sublimated suspending agent. In the method according to the invention, a suspension is produced from a ceramic and/or powder-metallurgical material and a suspending agent, the suspension is then exposed to a vacuum at least until the suspending agent has solidified/hardened/frozen, whereupon the suspending agent is sublimated and removed, the solidified structure of the suspension being obtained during the sublimation process.
