Exothermic reaction characteristics of continuously ball-milled Al/Ni powder compacts

Combustion of mechanically activated Ni/Al reactive composites with microstructural refinement tailored using two-step milling

“…Combustion temperatures ranged from~850 to 1070 K and followed the same trend as the combustion velocities. Also using the 3Ni/Al system, Hadjiafxenti et al [20,26] reported that increasing compact density increased combustion velocity from~0.9 to 5 cm/s due to increased thermal diffusivity [20]. When compared to nonmilled samples these studies show a slight increase in combustion velocities under analogous conditions [27].…”

A Comprehensive Investigation on the Electrophoretic Deposition (EPD) of Nano-Al/Ni Energetic Composite Coatings for the Combustion Application

“…The energetic composites can convert chemical enthalpy to thermal enthalpy rapidly, and mainly used as propellants, explosives additive in self-propagating high-temperature synthesis (SHS) [6][7][8][9][10]. They are largely categorized into bimetallic (such as Al/Ti [11] Al/Ni [12][13][14][15]), thermite (such as Al/CuO [16], Al/Al/ Fe 2 O 3 [17]) and metal-polymer (such as Al/Teflon™ [18]) types.…”

“…So far, the ANECCs burned in air or in micro-channels have been the central topic to evaluate the performance for sub-millimeter scale applications. The ANECCs with the nanoscale mixing ignited by a low ignition threshold energy can generate high reaction temperature because of the high energy after intermetallic exothermic reaction [14,15,19]. In the combustion mode of ANECCs, the pulse of energy is required to initiate the reaction.…”

Rapid fabrication and characterization of superhydrophobic tri-dimensional Ni/Al coatings

“…Recently, various methods for preparation of energetic nanomaterials reported in the literatures mainly focus on physical vapor deposition (PVD) [11], mechanical mixing method [15,16], electrophoretic deposition (EPD) [17], magnetron sputtering [18][19][20], ball milling (BM) [21] etc. Nevertheless, how to fabricate novel energetic coatings with the great resistance to variable environmental conditions on target substrate or chip effectively and rapidly is still a persistent challenge for nearly two decades.…”
