“…FSP alters the microstructure of composites to produce particular qualities by altering the surface to meet tribological requirements [40,41]. FSP is a popular fabrication process for manufacturing magnesium metal matrix nanocomposites [42,43]. During operation, a pin is inserted into the material with the rotating tool's shoulder touching the base metals.…”

Magnesium metal matrix composites (Mg-MMC) are versatile materials notable for their utilisation in automotive, aerospace, and manufacturing sectors due to their superior mechanical properties and high specific strength. Nanoparticle reinforcements at varying concentrations are used to improve the mechanical and tribological properties of the Mg alloy. In this paper, the effects of varying nanoparticles (namely silicon carbide, carbon nanotubes, titanium nanoparticles, and tungsten carbide) on different Mg alloys are discussed along with relevant manufacturing processes. From the literatures, Mg-MMCs are fabricated from AZ91 alloy with silicon carbide nanoparticle reinforcement of 1 wt-% composition, manufactured using ultrasonic-assisted stirring, which showed the best relationship in overall material properties over other nanoparticle reinforcements.

“…At low loaded electrode, roughness value would be high due to quick erosion of electrode. Due to quick erosion, bulk and lump deposition was formed on the surface that developed numerous globules and voids on the surface [23]. Hence, surface of the deposited workpiece would be poor.…”

Surface coating is covering the surface of workpiece with desired materials in order to improve the surface properties. Electrical discharge coating (EDC) is an electro thermal process, used for creating hard coating over the workpiece. EDM parameters play important role to improve the surface properties. In this present study, magnesium alloy is deposited using WC-Cu composite electrode by EDC. RSM is used to develop design matrix for carrying out EDC experiments. During experiments, compaction load, discharge current and pulse on time are controlled, whereas material deposition rate (MDR) and surface roughness (SR) are measured as response. The objective of this investigation is to predict the MDR and SR using neural network technique. ANN (Artificial neural network) model developed by back propagation algorithm is proposed in this study for predicting responses. ANOVA is conducted to identify the dominating parameter, which significantly affects the responses. Correlation coefficient between the ANN and RSM is 0.99, which is close to the unity for ANN. It was revealed that the prediction of proposed ANN was found to be excellent to the RSM model. MDR increased with increasing of discharge current and on time. SR decreased with increasing of applied load of the compaction, whereas when increase the current and pulse on time, SR increased.

Aluminium and its alloys are widely used for fabricating components are used in aircraft, automobile, defence and structural applications. Due to its light weight and high strength, it is applied in the various commercial purposes such as window, doors, construction member etc. However, machining of aluminium alloys using conventional machining methods is difficult. In this present investigation, an endeavour has been made to drill TiB2 in-situ aluminium metal matrix composite alloy developed using stir casting method. During the casting two different salts namely K2TiF6 and KBF4 are added with matrix materials to form TiB2. The paper is studied the surface roughness (SR) of drilled TiB2 in-situ aluminium metal matrix composite viz speed, feed rate and TiB2 addition. Empirical relationship is developed for SR in order to identify the dominating factors. The percentage contribution of SR is 96.35% that showed the empirical model is adequate. The normal probability plot showed the points of residuals are equally distributed over the straight line. The lack of fit value was 3.65 which is less than the standard point. Therefore, the SR model is satisfactory. SR increased with increasing of speed, feed rate and addition of TiB2. The removal of TiB2 particles causes small pits and voids due to the inclusion of reinforcement. The minimum SR was achieved at lowest speed (1260 rpm), feed rate (0.05 mm/rev) and TiB2 addition (2%). As speed and feed increased, the surface hardness increased.
