., IIT Roorkeee, 247667 (UA), India ramesfmt@iitr.ernet.in Keywords: Electroless coating, Nano -composite EL coating, Ag /Cu / Ni based EL coating Abstract Since the introduction of Electroless (EL) coating in 1946 by Brenner and Riddle, the process has been the subject of steady growth.
Here the nano-sized ferrite particles are co-deposited along with the Ni-P EL coatings.
Experimental The EL technique involves the autocatalytic reduction, at the substrate/solution interface, of cations by EL bath released from suitable chemical reducing agents.
The major component of the EL technique is the 'bath'.

After that, for 800 s at the same voltage and temperature in the studied ketone, the luminosity kinetics of the EL of the oxidized Al-anode and the current density flowing in the electrolytic cell previously described in [12] were recorded.
This is especially evident in the deep cavities of the Al-anode.
Obviously, the absence of the EL film of the Al2O3 film formed on the Al-anode in Ac is due to its disordered structure.
In the last two electrolytes, this process is accompanied by EL. 2.
The absence of EL in Al2O3 formed on the Al anode in Ac was revealed, which is probably due to its layered, disordered, and easily destroyed structure.

And the optimal mechanical properties of Al-Si-Cu-Mg alloys were obtained under the content ratio of Cu/Mg within 4, where the UTS and El reached 426 MPa and 6.3% after T6 treated, respectively.
Fig.5 displays the corresponding results of tensile properties including ultimate tensile strength (UTS), yield strength (YS) and percentage elongation (El).
Moreover, the M1 alloy shows favorable plasticity, and the value of EL reaches as high as 10.72%.The Al2Cu phase in M3 alloy is more rigid as well as bigger size.
(2) The maximum strength and percentage elongation for Al-Si-Cu-Mg alloys can be obtained by the heat treatment, where the Cu/Mg ratio is 4, the UTS, YS and El of alloy can reach 426.2 MPa, 295.0MPa and 6.3%, respectively.

Wadhawan et al. [3] reported the unpurified single-wall carbon nanotube (CNT) with impurities of magnetic Fe nanoparticles, with the greater microwave absorption properties affected by the cooperative effect.
Che et al. [2] also reported that the magnetic-nanoparticle/CNT composites exhibited improved microwave absorption properties, which are attributed to the better match between the dielectric loss and the magnetic loss.
