چکیده
Al-Si/7.5 wt.%Y2O3 coatings were prepared on Mg alloy with laser cladding to enhance the wear and corrosion resistance of substrate. The influence power microstructure properties coating discussed. results uncovered that consisted primarily Mg2Si, Mg17Al12, Mg2Al3, Al4MgY, α-Mg phases. Through calculating, it was observed crystal size decreased decrease in power. Y2O3 gave a better strengthening effect due fine-grain hard-phase strengthening. average hardness 1100 W achieved 312 HV, which approximately 4.2 times volume 22.2% Compared alloy, self-corrosion potential increased by 1.09 V, current density three orders magnitude.

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
