“…Thus, result in improvement of wear resistance because of the improvement of the hardness. The hardness of the composite is improved from 75 to 105 VHN (Mehra et al , 2018a, 2018b, 2018c, 2018d, 2018e). The influence of the Wt.% of TiC and sliding distance for weight loss are relatively high as compared to applied load as shown in Table II.…”

Purpose The RZ5 mg alloy is used in automotive and aerospace applications including helicopter gearboxes and aircraft components. These components are prone to the wear as per the demands. The present work is the study of the significance of hard particle/ceramic, i.e. titanium carbide (TiC) in RZ5 mg alloy to protect the machine components from wear. Design/methodology/approach The abrasive wear analysis of in-situ RZ5-TiC magnesium matrix composite is considered for the study. The primary focus of the present work is to analyze the effects of varying control parameters, i.e. Wt.% of TiC, sliding distance and applied load on the responses, i.e. weight loss and coefficient of friction. Full factorial design of the experiment based on statistical analysis is used. Findings It is observed that the individually Wt.% of TiC and sliding distance show the comparatively significant effect on both responses. Similarly, the interaction between sliding distance and Wt.% of TiC indicated the considerable impact on weight loss. The regression equations are developed and validated for estimating responses. It is observed that the percentage errors are not appearing more than 10 per cent of responses. Therefore, the close agreement between measured and predicted values shows the adequacy of the model. The control factor is optimized using multi-response optimization. The variations of the order of 2.47 and 2.35 per cent in target value of the coefficient of friction and weight loss are achieved. Originality/value The current manuscript provides a detailed abrasive wear statistical analysis of RZ5-TiC composite. The influence of control parameters on the responses using the full factorial design, the main effect plots and interaction effects are presented.

“…Taguchi method is an approach based on the orthogonal array and is having the capacity of giving less variance for the parameters which control the experiments when it is set at optimum condition [49]. B A M Pasha et al has stated that it is a method where the expenses are meager and are being used nowadays by the researchers to formulate a relationship between the impact of parameters and it is interactions in experiments [48].…”

“…In this work done by Satnam Singh et al the selected the normal load, track diameter and sliding distance as the parameters which are varied at 3 levels [50]. It is written by D Mehra et al that they have used an L27 orthogonal array, which means there are 27 experiments that are represented in the 27 rows followed by three levels at 13 columns [49]. M A Almomani has noted that the effect of test parameters and percentage weights of the reinforcing materials against the wear rate is being analyzed by using Taguchi's L16 orthogonal array at the levels of normal load and sliding speed [51].…”

Composite materials are being widely studied for the last few decades, and it has optimized the day to day applications in the engineering field. In this advancement, the use and development of metal matrices was a significant outcome that concentrated on the addition of many particulate materials in a metal matrix at nano and micro levels. Among these Magnesium, metal matrices are having a high potential, especially in transport, defense, and aircraft industries. Many research works are being carried out to use the capabilities of Magnesium and has provided excellent results. This paper is an overview of the development, processing, and improvement of properties in Magnesium alloys. Various manufacturing processes such as self-propagating high-temperature method, stir casting, laser cladding, and powder metallurgy has been used to develop the magnesium composites for increasing the properties by using various wt% of reinforcements added in the matrix. The improvement in mechanical properties such as tensile strength, yield strength, hardness and tribological properties such as wear rate is reviewed. The different properties and capabilities of Magnesium alloys such as AZ31, AZ91, and ZE41 is also discussed from the various research works.

“…The literature below shows some of the research activities in the property enhancement of magnesium and its alloys. The mechanical behaviour of magnesium composite with titanium carbide was investigated, and a considerable improvement in hardness and tensile strength was observed (Mehra et al , 2018). The mechanical behaviour of magnesium composite with TiO 2 was investigated (Hassan et al , 2017), and the improved ductility was observed.…”

Purpose The purpose of this study is to analyse and optimize the wear parameters of magnesium metal-metal composite. Materials with lesser weight attract both the researcher and industrialists, as it exhibits the performance improvement in the automotive and aerospace industries. The enrichment of mechanical and tribological properties of the existing magnesium focussed the development of new metal–metal composite. Design/methodology/approach Metal–metal composite with magnesium matrix was synthesized through the disintegrated melt deposition technique with the addition of titanium, aluminium and boron carbide particles. The wear performance of the composite was experimented with the dry sliding wear test by considering load, sliding velocity and sliding distance. Findings The wear rate of the composite is analysed statistically, and the significance of wear parameters on the wear performance of metal–metal composite is observed. The worn pin surface and the wear debris collected during the wear experiments were exposed to the microscopy analysis to seize the dominating wear mechanisms. Originality/value The wear performance of the developed magnesium composite was analysed and discussed in detail with the support of scientific evidence, i.e. worn surface and debris analysis express the wear mechanisms.
