In the proposed work, sodium dodecyl sulfate (SDS) is used as a surfactant for carbon nanotubes, to fabricate multi walled carbon nanotube-aluminium metal matrix composites (MMCs). This paper presents the comparison study of SDS coated and non-coated multi walled carbon nanotube (MWCNT) mixed with Al6065 by stir casting technique. The presence of low molecular weight surfactant treated with MWCNT was investigated by Fourier Transform Infrared (FTIR) spectroscopy analysis. About 1 wt. % of MWCNT is used as a filler metal in Aluminium and the dispersion characteristics of SDS coated and non-coated Carbon Nanotubes in the composite is examined using a scanning electron microscope (SEM). The comparison study of SEM analysis showed thatthe MWCNT coated with SDS has good dispersion stability and considerable reduction in agglomeration to obtain agglomeration free composites. The mechanical properties and wear characteristics of the MWCNT-Aluminium matrix were studied as per the American Society for Testing and Materials (ASTM) standards. The results of SDS coated MWCNT exhibits exceptional properties with increase in the tensile strength, compressive strength, hardness, and wear characteristics of the reinforced metal matrix. ABSTRAK:Natriumdodesilsulfat (SDS) digunakan sebagai surfaktan pada karbon nanotiub, bagi menghasilkan multi dinding karbon nanotiub-komposit matriks logam aluminium (MMCs). Perbandingan dibuat dalam kajian ini dengan membandingkan salutan SDS dengan bukan-salutan multi dinding karbon nanotiub (MWCNT) yang bercampur A16065 melalui teknik kacauan acuan. Kahadiran berat surfaktan molekul ringan terawat dengan MWCNT dikaji mengguna pakai analisis spektroskopi Penjelmaan Fourier Inframerah (FTIR). Kira-kira 1 wt.% MWCNT digunakan sebagai pengisi besi dalam Aluminum dan ciri-ciri penyebaran salutan SDS dan bukan-salutan karbon nanotiub dalam komposit diteliti menggunakan pengimbas mikroskop elektron (SEM). Perbandingan analisis SEM menunjukkan, salutan MWCNT dengan SDS mempunyai kestabilan penyebaran dan berkurang dengan banyak dalam pengaglomeratan bagi mendapatkan komposit bebas pengaglomeratan. Ciri-ciri mekanikal dan haus matrik Aluminium-MWCNT dikaji berdasarkan piawai Persatuan Pengujian Bahan Amerika (ASTM). Keputusan MWCNT salutan SDS mempunyai ciriciri luar biasa dengan kenaikan kekuatan tegangan, kekuatan mampatan, kekerasan, dan ciri-ciri haus pada kekuatan matrik logamn.
