As the feedstock powders typically have sizes from micrometres to above 100 micrometres, the lamellas have thickness in the micrometre range and lateral dimension from several to hundreds of micrometres [1].
Between these lamellas, there are small voids, such as pores, cracks and regions of incomplete bonding (Fig. 1).
Ge Y. et al [21] employed the LB remelting to modified of plasma sprayed micro-structured Al–Si based and 1 wt.% nano-structured Si3N4 coating fabricated on an AZ31B magnesium alloy.

The bands observed at 2924cm-1 and 2359cm-1 nearby suggest the stretching vibrations of C-H group and stretching vibrations of P-H and Si-H.
The bands 669cm-1 and 562cm-1 nearby are belonged to the Si-O bending vibration and Al-O stretching vibration.
