“…The microstructures from the nickel-rich liquid tions discussed in this article cannot be readily applied to indicated some black particles which may be graphite (Figconditions involving nonequilibrium conditions or nonequiure 5); however, further characterization by X-ray diffraction librium solubility. [29,30] In addition, computational thermodyand scanning electron microscopy is needed to confirm this namic models need to be extended to describe the amorphous theory. The relationship between the local composition and phase formation and must be coupled with the dendrite phase evolution is important for maintaining the cracking growth theories for laser-processing conditions.…”

The stability of tungsten carbide particles in iron-rich and nickel-rich liquid during the laser surface alloying (LSA) process was investigated. Kinetic calculations indicate a rapid dissolution of tungsten carbide particles in iron-rich liquid, as compared with the dissolution rate in nickel-rich liquid. Optical microscopy indicated a heterogeneous microstructure around the tungsten particles that is in agreement with concentration gradients predicted by kinetic calculations. The work demonstrates the applicability of computational thermodynamics and kinetic models for the LSA process.

“…Laser surface alloying LSA of aluminium is useful surface treatment technique because it offers advantage of localized processing and with proper process parameters it is capable of homogenous structure formation with strong bonding to substrate surface. Moreover, there are various reports confirming that the laser surface alloying of aluminium does improve considerably the tribological characteristics at the surface [1,2,[18][19][20][21][22][23][24].…”

Ceramic particles powder feeding into surface layer of engineering metal alloy is a well-known and widely used technique. New approach into the topic is to obtain finely distributed nano-sized particles involved in the aluminium matrix using the traditional laser technology. In this paper are presented results of microstructure investigation of cast aluminium-silicon-copper alloys surface layer after heat treatment and alloying with ceramic carbides of WC and ZrO 2 using high-power diode laser. The surface layer was specially prepared for the reason of reducing the reflectivity, which is the main problem in the up-to-date metal matrix composites production. With scanning electron microscopy, it was possible to determine the deformation process and distribution of WC and ZrO 2 ceramic powder phase. Structure of the surface after laser treatment changes, revealing three zones-remelting zone, heat-affected zone and transition zone placed over the Al substrate. The structural changes of ceramic powder, its distribution and morphology as well as microstructure of the matrix material influence on functional properties, especially wear resistance and hardness of the achieved layer, were investigated.
