بررسی تأثیر فرآیند اکستروژن بر ریزساختار و استحکام کامپوزیت Al6061-SiC
Al-SiC composites are among the most demanding metal matrix composites due to their excellent strength, good ductility, good corrosion resistance, low coefficient of thermal expansion and reasonable price. Manufacturing of cast metal matrix composites usually involves some problems such as inhomogeneous distribution of the particles due to poor wetability of ceramics to molten alloys, porosity ...
متن کاملAN INVESTIGATION ON CORROSION BEHAVIOUR OF A356-10 VOL.% SiC COMPOSITES IN HCl SOLUTIONS
In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...
متن کاملTin (II) Chloride a Suitable Wetting Agent for AA1200 - SiC Composites
SiC reinforced Aluminum samples were produced by stir casting of liquid AA1200 aluminum alloy at 600-650oC casting temperature. 83μm SiC particles were rinsed in 10g/l, 20g/l and 30g/l molar concentration of Sncl2 through cleaning times of 0, 60, 120, and 180 minutes. Some cast samples were tested for mechanical properties and some were subjected to heat treatment before testing. The SnCl2 rins...
متن کاملThermal shock and oxidation resistant gradient coating based on yttrium silicate for C/SiC composite
Yttrium silicate coating[5, 6] is a promising candidate for oxidation resistant coating for its low oxygen diffusion coefficient and similar thermal expansion coefficient with silicon carbide. Webster et. al.[7] had prepared yttrium silicate coating on C/SiC using Y2O3/SiO2 slips by slip casting and sintering. The selected sintering parameters were 3 h at 1600 °C in flowing argon. The coating c...
متن کاملPreparation, Characterization, and Modeling of Nanoporous Silicon Carbide Membranes
Silicon carbide (SiC) is a promising material for the preparation of high temperature membranes [1-5] due to its many unique properties such as high thermochemical stability, high thermal conductivity and resistance to abrasion. In our studies, SiC microporous membranes are fabricated using two different techniques. The first approach involves the pyrolysis of pre-ceramic polymeric films [3,4],...
