Metal matrix composite production by means of laser dispersing of SiC and WC powder in Al alloy

Wear Resistance Enhancement of Al6061 Alloy Surface Layer by Laser Dispersed Carbide Powders

“…Recently, for the Al6061 substrate, the combined wire and powder deposition by laser [ 21 ] and also selective laser melting of pure Al and Al–Cu–Fe–Cr powder grains for production of reinforced MMC structures with post-aging treatment [ 22 ] were reported. These works, including also our previous reports on the dispersing of SiC powder grains into Al6061 (AW–AlMg1SiCu) alloy [ 23 , 24 ] and SiC [ 25 ] and WC or TiC [ 26 ] powders (mainly in Ti6Al4V alloy), indicate the growing interest and confirm the research efforts in laser dispersing. However, plenty of the studies were performed for different substrates, various dispersed powder materials, and with laser sources of various characteristics—see Table 1 where data for the case of Al-based alloys are collected showing the novelty of this work too.…”

“…The head was tilted off perpendicularly to the specimen surface by a 15° angle to avoid back propagation of radiation into the optical fiber and laser resonator. Details of the experimental set-up presented schematically in Figure 1 have been described in previous works [ 23 , 24 , 25 , 26 ].…”

Evaluation of mechanical properties of 1060-Al reinforced with WC particles via warm accumulative roll bonding process

“…In recent years, the high hardness of tungsten carbides (WCs) led to their emergence as a new reinforcement particle in AMMCs [4][5][6][7][8][9]. WC-AMMCs are manufactured through several methods such as high-energy milling [4], sputtering [5], plasma and high-velocity oxygen fuel sprays [6], and laser alloying techniques [7][8][9].…”

High energy milling method to prepare Al/WC composite coatings in Al–Si alloys

“…Bolelli et al obtained WC-CoCr cermet coatings deposited onto an aluminium alloy substrate by High Velocity Oxygen-Fuel flame-spraying [13]. In addition, Jendrzejewski et al [14] prepared SiC and WC/Al composite and Staia et al [15] prepared A-356 aluminum/WC composite both by laser. Nevertheless, the density of WC was much higher than Al, and the sintering between WC particles was not possible below 1500 • C, so there is limitation of preparing WC reinforced aluminum composite alloys by laser or spray.…”

“…In order to improve or modify the properties of materials surface, Al-based ceramicreinforced metal matrix composites have attracted the attention of researchers for many years because of their potential for structural applications [6][7][8][9][10][11]. Recently, tungsten carbide (WC) became a new class of materials as the reinforced particles in aluminum alloys because of very high hardness [12][13][14][15]. Man et al prepared TiC + WC reinforced metal matrix composites coatings on Al 6061 by laser induced reaction synthesis [12].…”
