چکیده
Al86Ni8Co1La1Y2Gd2 amorphous coatings were prepared using cold gas kinetic spray technology. The results show that are achieved with the porosity about 3.2%, thickness 893 ?m, amount of phase 82.5%, hardness 300HV0.2. corrosion potential and anti-corrosion life 7075 T6 alloy aluminum ?0.78 V 72 h, respectively. electrochemical analysis neutral salt ?0.69 274 h for Al-based coatings, Therefore, is 3.8 times alloy. Besides, failure mechanism was analyzed TEM in this investigation. In a word, keep dense structure, high content, favorable stabilizing ability longer life. That is, have better comprehensive properties. these findings indicate present technique can protect very well they be considered to used aviation field.

15 صفحه اولNanoparticles of amorphous cellulose and their properties
Method of preparation and some properties of amorphous cellulose nanoparticles (ANP) have been described in this paper. It was shown that ANP have spherical shape and are characterized by high degree of pantamorphia, low DP and increased content of sulfonic groups. The amorphous nanoparticles of cellulose are completely hydrolyzed by cellulolytic enzymes with forming of glucose. Concentrated pa...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
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...
15 صفحه اولPhysics of Amorphous Solids: their Creation and their Mechanical Properties
In this short review I summarize some progress achieved in my research group regarding the glass transition and the mechanical properties of the resulting amorphous solids. Our main concerns were on the one hand to understand the extreme slowing down over a narrow range of temperatures which results in a viscosity so high that the materials behave as solids under small mechanical strains. On th...
