摘要： The invention concerns a method for producing a ceramic material, the method comprising the following step: forming a ceramic material by implementing a first chemical reaction at least between a first powder of an intermetallic compound and a reactive gas phase, a liquid phase being present around the grains of the first powder during the first chemical reaction, said liquid phase being obtained from a second powder of a metal compound by melting the second powder or following a second chemical reaction between at least one element of the first powder and at least one metal element of the second powder, a working temperature low enough to prevent the first powder from melting being imposed during the formation of the ceramic material.

摘要： A dense ceramic workpiece is made by a process of combining a powdered (312) component, e.g., Ti3SiC2, with a powdered component that is soluble in the (312) component, e.g., TiSi2 in Ti3SiC2, forming the mixture into a green body, heating the green body under pressureless sintering conditions to a temperature above a point at which a liquid is formed but below the melting point of the (312) compound to yield a dense ceramic workpiece, and thereafter cooling the dense (312) ceramic workpiece.

摘要： Products having single phases or solid solutions of the formula M3X1Z2 wherein M is a transition metal, X is Si, Al or Ge and Z is B, C or N can be prepared by taking a powdered mixture containing M, X and Z to a temperature of about 1000 DEG C to about 1800 DEG C, optionally simultaneously under a pressure of about 5 MPa to about 200 MPa. The products so formed have excellent shock resistance, oxidation resistance and machinability. The products may also be present as composites, preferably composites which are in thermal equilibrium with the single phase or solid solutions of the formula M3X1Z2.

摘要： A method of producing a single-phase composition Mn+1AzXn, where n lies within a range of 0.8-3.2, where z lies within a range of 0.8-1.2, where M is at least one metal taken from the group of metals Ti (titanium), Sc (scandium), V (vanadium), Cr (chromium), Zr (zirconium), Nb (niobium) and Ta (tantalium), and where X is at least one of the non-metals C (carbon) and N (nitrogen) and where A is at least one of the chemical elements Si (silicon), Al (aluminium) and Sn (tin) or a compound of said elements such that the final, desired compound will include the components Mn+1AzXn, wherein the method also comprises forming a powder mixture from said metal, non-metal and said chemical element or compound of said elements, and igniting said powder mixture under an inert atmosphere so as to prevent promotion of dissociation, wherewith the components react. The method is characterised by keeping the reaction temperature at or above the temperature at which components are caused to react but beneath the temperature at which the single-phase composition dissociates.The invention relates primarily to the production of the single-phase material Ti3SiC2.

摘要： A power tool has an electric motor with a stator assembly and an armature rotatable within the stator assembly. A commutator (50) is rotatable with the armature and is connected to the armature via a shaft (42). The commutator (50) has an outer layer (53) formed from a titanium graphite material. Brushes (62 and 64) are associated with the commutator (50) and are held in an end plate. The brushes (62 and 64) are formed from a titanium graphite material.
