Table 4 Brief summary of Mg-MC surface MMCs by FSP as available in the literature

AZ31-SiC

SKD61

ShD-12mm, PiD-4mm, Pil-1.8mm

Cylindrical

RS-1500 rpm TS-25-200 mm/min

1. Addition of SiC to AZ31-Mg matrix leads to refinement of microstructure and increase in hardness to about 80Hv. 2. At elevated temperatures fine grain microstructure produced by FSP of AZ31 Mg-Sic is maintained as compared to fine grain micro structure of AZ31 Mg-matrix produced by FSP without SiC addition.

AZ31-SiC

H-13

ShD-18mm, PiD-3.4mm, Pil-3mm

Cylindrical

RS-900, 1400, and TS-200, 250, and 1800 rpm 300 mm/min Tilt angles 0^∘ and 3^∘

1. Increasing the rotational speed /traverse speed ratio and FSP pass number leads to uniform distribution of SiC in magnesium matrix.

AZ91-SiC

Steel

ShD-15mm, PiD-3.54mm, Pil-2.5mm

Cylindrical

RS-710–1400 rpm TS-12.5–63 mm/min

1. The grain size is increased and hardness is decreased with the increase in tool rotational speed. 2. The grain size decreases and hardness increases by increasing the traverse speed. 3. Multi pass FSP distributes SiC particles uniformly in AZ91-Mg matrix.

AZ31-SiC

HSS

SOD-24mm, SID-8mm

Concave

RS-400 rpm TS-30 mm/min

1. Direct FSP (DFSP) results in homogeneous and distributes SiC particles uniformly in one pass only as compared to conventional multi pass FSP. 2. The optimal parameters calculated for uniform distribution of SiC in AZ31-Mg matrix are tool rotational speed = 400 rpm, Tool traverse speed v = 30 mm/min, tool tilt angle= 0.5^∘, and plunge depth d=0.3 mm.

AZ31-TiC

HCHCr steel

ShD-18 mm, PiD-6 mm Pil-5 mm

RS- 1200 rpm TS-40 mm/min Axial Force- 10 KN

Homogenous distribution of TiC particles in the magnesium matrix without any inter-facial reaction and formation of clusters.
