A review of the design, properties, applications, and prospects of Ni-based composite powders

Electroless Metallization of the Elements: Survey and Progress

“…The preparation of composites to enhance EL Ni properties such as wear-resistance, hardness, corrosion protection, and catalytic properties via the use of particulate additives such as metal oxides, ,, metal sulfides, silica, alumina, , diamond, nitrides, , carbides, − graphene oxide, or polymers , has been a long-standing area of interest that has continued in recent years. Extensive reviews are available for readers interested in additional information. ,,,, Here we present examples that reflect the recent developments in “smart” composites, i.e ., composites capable of responding to a stimulus to enable a desirable outcome or function.…”

Reactive mixing performance for a nanoparticle precipitation in a swirling vortex flow reactor

“…Advanced functional nanoparticles have wide applications in the fields of pharmaceuticals [1] , drug delivery [2] , energy storage [3] , dyes [4] , and cosmetics [5] . Many preparation techniques have been developed to control particle size and its distribution, among which flash nanoprecipitation can be seen as a promising approach.…”

Research on the preparation of Ni/Al2O3 powder by fluidized crystallization granulation–hydrogen reduction

“…1,2 Nickel-based ceramic composite powder refers to a composite ceramic powder formed by coat-ing the surface layer of nickel metal with ceramic powder, which has the properties of the nickel cladding layer and the ceramic core. [3][4][5][6] Alumina has good toughness, high hardness, good oxidation resistance, and high-temperature stability. 7 Alumina is often used as a particle phase to enhance the strength of metal-based materials; however, because alumina is not wettable with metals, problems, such as uneven particle distribution, are encountered, and coating the alumina surface with nickel can promote uniform particle dispersion in the matrix, thereby improving the material properties.…”

“…8,9 Existing processes for the preparation of coated composite powders mainly include chemical plating, pressurized hydrogen reduction, chemical vapor deposition, electrochemical reduction, and solution crystallizationhigh-temperature reduction. 3,[10][11][12] Currently, the most commonly used process is chemical plating, where the common reducing agents include sodium hypophosphite, sodium borohydride, aldehydes, and hydrazine hydrate, which often contain impurities, such as phosphorus, boron, and carbon and often result in the presence of nickel in alloy form. 5,[13][14][15][16] Zhang et al prepared Ni/Al 2 O 3 composite powder using acidic chemical plating, and various complexing agents, such as lactic acid and sodium acetate, were added to the plating.…”
