Fabrication of Al/TiB2 composites through gas pressure infiltration

Fabrication and microstrain evolution of Al-TiB2 composite coating by cold spray deposition

“…friction stir processing [16][17][18] , gas pressure infiltration 19,20 , in-situ reactive processes 21,22 , etc.…”

“…15 The TiB 2 -reinforced AMCs (Al-TiB 2 ) have been achieved by various manufacturing methods, e.g. friction stir processing, [16][17][18] gas pressure infiltration, 19,20 in-situ reactive processes, 21,22 and so on. Meanwhile, Al-TiB 2 composites are also employed as coatings to improve the wear resistance and hardness of aluminium and its alloys, especially in the structures where the properties of the surface layers are of primary importance.…”

Infiltration characteristics of liquid AZ91D alloy into short carbon fiber preform

“…Previous work on the infiltration has been conducted thoroughly on process and process modeling. Specific process routine was developed based on the liquid metal infiltration to apply external pressure to overcome the pressure differential due to capillary at the infiltration front [6], such as squeeze casting [7,8], gas pressure infiltration [9], vacuum infiltration [10,11], and extrusion directly following vacuum infiltration technique (EFVI) [12,13]. A more quantitative understanding of the infiltration behavior would enable better selection of infiltration materials, surface preparation, and processing parameters so that processing practice may be optimized [14].…”
