Producing TiC-Al Cermet by Combustion Synthesis of TiC Porous Skeleton with Spontaneous Infiltration by Aluminum Melt

Fabrication of MAX‐Phase Composites by Novel Combustion Synthesis and Spontaneous Metal Melt Infiltration: Structure and Tribological Behaviors

“…For instance, the good wettability of a porous ceramic body TiC and Ti 3 AlC 2 -TiC after SHS allowed it to be infiltrated by a metal melt spontaneously due to the capillary effect and ensured high interfacial adhesion in the resultant composite, increasing its physical and mechanical properties. [24,[31][32][33][34] A new approach that combines the SHS method and spontaneous infiltration of the metal melt can significantly simplify and reduce the cost of manufacturing IPCs, specifically MAX-metal composites. Many published studies describe successful attempts to fabricate MAXMETs, such as Al-Ti 3 SiC 2 , [35,36] Mg-Ti 3 SiC 2 , [37,38] Ag-Ti 3 SiC 2 , [39][40][41] Bi-Ti 3 SiC 2 , [39] Pb-Ti 3 SiC 2 , [42] and Cu-Ti 3 SiC 2 ; [43][44][45][46] however, the most popular methods for fabricating these composites are spark plasma sintering, hot pressing, and traditional elemental powder sintering.…”

“…The infiltrated metal melt does not flow out and remains stable in the pores of the ceramic skeleton since it is retained by capillary forces until the metal is completely crystallized, providing MAXMET production with the IPC structure. [50] The process of MAX-phase structure formation using the SHS method may take some time after the active combustion phase is completed. The authors of refs.…”

“…Preparing the volume of metal melt required for infiltration using the modified scheme was performed separately in an electric furnace, which also made it possible to control the melt supply to the hot SHS skeleton after synthesis. [24,50] Maintaining the necessary time interval after SHS and before infiltration onset ensured the complete occurrence of secondary reactions for the structure formation in the SHS skeleton and the formation of the target MAX phase. This method was used to prepare a Ti 3 AlC 2 -Al composite [33] and a TiC-Al cermet [31] with a relatively low residual porosity (less than 5-10%) and sizes up to 250 mm with a diameter of approximately 23 mm.…”

Properties of Al2O3/Ti/Ni Composite Obtained by Slip Casting with Different Metal Phase Content

“…Ceramic-metal composites, due to their unique properties, are an object of desire as functional and construction materials in specialized applications of electronic technology, medicine and aeronautics [ 1 , 2 ]. The introduction of the metallic phase dispersion into the ceramic matrix enables the shaping of a number of composite properties, such as its thermal, magnetic and electrical conductivity [ 3 , 4 , 5 ]. Considering the load-bearing capacity of this group of composites, it should be noted that the presence of plastically deformable particles gives the opportunity to dissipate energy in the loaded composite by plastic deformation of the metallic phase without losing the cohesion of the ceramic matrix [ 6 ].…”

Manufacturing of Al2O3/Ni/Ti Composites Enhanced by Intermetallic Phases

“…The selection of appropriate metallic components allows the sintering process to create new phases [2][3][4], including intermetallic ones [5][6][7], thereby obtaining unique properties of the composite [7][8][9]. Taking the advantage of the properties of the individual materials (e.g., the electric conductivity and ductility of metal and the hardness and heatresistance of ceramics) has made ceramic-metal composites very promising materials for use in biomedical [10], aerospace [11], electrotechnics [12], and other engineering applications [13,14].…”
