چکیده

abstract


Compared to other alloys of Aluminium, AA5083 alloy is one of the most promising material which is used in corrosive and cryogenic environment. The effect of the purity and weight percentage of Multiwall Carbon Nanotube (MWCNT) added to the Aluminium alloy is the widely focused research area in the field of Cryogenics in recent years. In this present work, MWCNT having more than 98% purity, 5–20 nm mean diameter (D) and 1–10 m average length (L) was used with different compositions like 1, 1.25, 1.5 and 1.75 by weight % to improve the corrosion behaviour of the Aluminium Nano Metal Matrix Composite (ANMMC). The results show Aluminium alloy AA5083 reinforced with MWCNT exhibit nominal changes in density than pure AA5083 and the uniform immersion corrosion tests (ASTM-G31) of the same composite in 90 ml of HCl shows increase in corrosion resistance as compared to AA5083 alloy.

3. Conclusion


From the present experimental work the following details were concluded


1. AA5083/MWCNT in weight percentages of 0, 1, 1.25, 1.50 and 1.75 wt% were successfully fabricated using compo-casting method.


2. Uniform dispersion and reduced cluster formation of MWCNT into the matrix material of the produced AA5083/MWCNT nano metal matrix composite with an improved hardness.


3. Hardness of the cast specimens has increased by addition of MWCNT in the matrix material, from 74 BHN for the alloy AA5083 to 84 BHN for 1.75 wt% of reinforced composite and considerably increased for 1, 1.25 and 1.5 wt% addition of MWCNT.


4. AA5083/MWCNT composite have better corrosion resistance than the AA5083 alloy in HCl (dil) at room temperature.
