Abstract An enormous amount of research is conducted on aluminium alloys on friction stir process, despite magnesium alloy reporting severe weight reduction when compared to aluminium alloys; a very slight amount of research was testified by friction stir processing of magnesium alloys. Magnesium is highly reactive and susceptible to corrosion in the presence of an aggressive environment. This highly corrosive nature of magnesium limits its applications. Surface properties like crystal structure, composition, and micro structure influence the corrosion and wear property of the material. Coating and alloying like laser surface modifications are performed to passivate magnesium surface from corrosion. Coating techniques, however were found to be insufficient in corrosion protection due to coating defects like pores, cracks, etc, and adhesion problems caused due to poor surface preparation of the substrate, and also impurities present in coating which provides micro galvanic cells for corrosion. Current study analyses the detailed overview of different types of Surface modification methods such as Physical vapor deposition, Chemical vapor deposition, Chemical conversion coating, Ion implantation coating techniques and also work focuses on few of Alloying or Surface processing methods such as Laser surface modification namely Laser surface melting, Laser surface cladding, Laser Shot Peening, Laser surface alloying and Friction stir processing (FSP). Friction stir processing a novel method derived from friction stir welding is used as surface modification method, which modifies micro structure, composition of surface layer without changing bulk properties, for enhancing corrosion resistance property. FSP enhances the micro structure and homogenizes but it is also eliminating the breaking up of the brittle- network phases and also cast micro structure imperfections. Indeed FSP can produce particle and fiber-reinforced magnesium-based surface composites. FSP empowers the manufacturing of magnesium by adding additives. Comparison of the different methods of coating and surface modification has been compared with FSP

Friction Stir

Multipass friction stir processing (MP-FSP) is a solid-state surface modification technique, which was developed based on the simple principle of FSW. Aluminium plates were subjected to MP-FSP from 1 to 14 passes along the longitudinal direction with the specified process parameters such as rotational speed of 1000 rpm and travel speed of 70 mm/min and axial force of 15 kN. Subsequently, similar process parameters had followed by doublepass friction stir processing (DP-FSP) in order to help determine the effectiveness of multipass in creating high strength of aluminium alloys. Now-a-days extensive research had focused on various process parameters such as rotational speed, traverse speed, tool design on processing of aluminium alloys and proficiently enhanced material properties. This technique has considered mostly development of green technology, which is energy efficient and environment friendly technique. Experimentally proven that the Al-Zn-Mg-Sc alloys are characterized through OM, FESEM, DSC, SEM, TEM, and mechanical properties. The tensile strength and ductility of the MP-FSP specimen improved significantly to 122.48%, and 42.55% respectively, but hardness decline to 4.84% as compared to DP-FSP. This is due to not only for refinement of cast dendritic structure and eliminate segregation in the as-cast alloy, but also to the refining of grains, such as the uniform distribution of Al3Sc and hardening precipitates. To aim of this research work is to mainly focusing on MP-FSP may enhance mechanical properties better than DP-FSP and useful for macroscale applications.

Dissimilar Alloys

The use of aluminium alloys continues to grow in many applications to mention a few aerospace, automotive, electronics, electricity, construction and food packaging. With so much demand there is a new interest in welding of dissimilar aluminium alloys. Some of the welding techniques used to join dissimilar aluminium alloys include friction stir welding and TIG welding. The welding of dissimilar alloys affects the mechanical properties negatively due to porosity and cracking during the welding. This then suggests that there should be a process which can be used to improve the dissimilar alloys mechanical properties post its production. Friction stir processing was found to be one of the mechanical techniques that could be used to improve the mechanical properties of the material. This paper reports on the literature on the friction stir welding, TIG welding and friction stir processing techniques published so far, with the aim to identify the gap in the use of friction stir process as a post processing technique of the weld joints.

The Status

There is an increase in reducing the weight of structures through the use of aluminium alloys in different industries like aerospace, automotive, etc. This growing interest will lead towards using dissimilar aluminium alloys which will require welding. Currently, tungsten inert gas welding and friction stir welding are the well-known techniques suitable for joining dissimilar aluminium alloys. The welding of dissimilar alloys has its own dynamics which impact on the quality of the weld. This then suggests that there should be a process which can be used to improve the welds of dissimilar alloys post their production. Friction stir processing is viewed as one of the techniques that could be used to improve the mechanical properties of a material. This paper reports on the status and the advancement of friction stir welding, tungsten inert gas welding and the friction stir processing technique. It further looks at the variation use of friction stir processing on tungsten inert gas and friction stir welded joints with the purpose of identifying the knowledge gap.

Plasma physical vapor deposition method was most widely used to prepare ultrafine Al powders. Direct Current Arc Plasma (DCAP) and Radio Frequency Induction Plasma (RFIP) were adopted individually to produce Al powders with different particle size. The micro structure such as grain size, morphology and crystal phase was examined by SEM, TEM and XRD methods. The results show that the Al production by RFIP was better than by DCAP. DCAP has outstanding advantages in producing nanoAl powders with the particle size below 300nm while the RFIP is better to produce Al powders with the particle size 300nm to 1 μm.
