Al matrix composites fabricated by solid-state cold spray deposition: A critical review

Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Effect of Process Parameters on Properties of Cold-Sprayed Zn–Al Composite Coatings

“…For a particular material, the degree of plastic deformation depends on the particle velocity [ 8 ]. Based on the above discussion, cold-spraying technology is suitable for heat-sensitive materials [ 5 , 9 ], and appropriate process parameters can improve the particle deposition effect and coating performance [ 10 ].…”

Microstructure, mechanical and wear resistance properties of low-pressure cold-sprayed Al-7 Mg/Al2O3 and Al-10 Mg/Al2O3 composite coatings

“…Commonly used reinforcement particles in MMC coatings include ceramic particles (Al 2 O 3 , SiC, B 4 C, TiB 2 ) [2], carbon fibre, synthetic diamond particles [3], carbon nanotubes and graphene [4]. The size, weight fraction and distribution of the reinforcement particles and the interfacial bonding between the matrix and reinforcement predominately determine the properties of MMC coatings [5]. For example, a higher weight fraction of reinforcement particles and a shorter mean free path between these particles improve the load sharing capacity, hardness and resistance to wear [6].…”

“…Various MMC coatings and processing methods have been developed to optimise their microstructure and properties. After half a century of development, a subclass of MMCs, aluminium matrix composite (AMC) coatings, has been widely used in the transport industries due to their lightweight, high strength and good wear resistance [5,7]. For example, AMCs have been applied on Al 6xxx series used in aircraft floor panels to improve its surface corrosion and wear resistance properties and repair worn-out aerospace gearboxes [8].…”

“…For example, AMCs have been applied on Al 6xxx series used in aircraft floor panels to improve its surface corrosion and wear resistance properties and repair worn-out aerospace gearboxes [8]. Moreover, AMC coatings have recently received increasing attention due to their large potential applications in repair, especially for aircraft and marine components [5]. The various processing techniques that have been used to manufacture AMC coatings include solid-state processing (e.g.…”

“…plasma spray) and additive manufacturing (e.g. cold spray) [5]. Among these processes, the liquid-state and powder metallurgy techniques have been widely used in industry.…”
