While numerous coating materials are available to counteract erosion corrosion damage in the aforesaid components, iron-based amorphous coatings are thought to be more effective. This paper concentrates on the selection of the coating material for AISI 304L SS. In this investigation, WC-10Co-4Cr coating was selected on stainless steel substrate using MCDM techniques. Fuzzy analytic hierarchy process (FAHP) is the technique applied to calculate the weights of criteria and combinative distance-based assessment method (CODAS) is utilised for ranking the alternatives.

Access to complex data and the advancements in network analytics have enabled researchers and practitioners to explore new horizons of global operations. These advancements have further contributed to the study of global supply chains from a business ecosystem perspective. Within this perspective, organisations can be studied using connected network analytics techniques. The present study explores the supply chain structure of the auto industry across five backward tiers. Based on the study of the auto industry global supply chain along five backward tiers, this study explores the effect of firms' position in supply chain structure on the firms' profitability, asset risk, and price volatility. The research methods proposed in this study apply to any industry globally.

Metal matrix composites have emerged as remarkable materials due to their superior characteristics when compared to other matrix composites. The most promising lightweight materials are composed of aluminium alloys, which are utilised in the marine, aerospace, and automotive industries, but their use is limited due to their average strength and moderate wear resistance. In terms of wear resistance, AMCs beat their monolithic counterparts that are unreinforced. Stir casting was used to produce aluminium matrix composites made of 413 aluminium alloys with particulate fly ash reinforcements weighing 3%, 6%, and 9%. Wear tests were conducted in pin-on-disc wear tester following ASTM Standard G99-05 guidelines. The goal is to explore the effects of sliding speed, load, sliding distance, and reinforcing weight percentage on coefficient of friction and specific wear rate using ANOVA and grey relational analysis. Sliding distance (18.48%), load (17.39%) are the parameters which have extreme significance on composites' GRG followed by sliding speed (10.33%) and reinforcement (4.35%). By using grey relational analysis, wear behaviour can be predicted successfully.

The paper also aims to define the most broad and influential segments of Facebook users and their collective traits in terms of shopping behaviour, fashion brand preference, price preference, liking for quality, demand of new fashion, consumer social behaviour, etc. An online survey was conducted in which 158 users participated through structured questionnaire. The results give a clear idea about the consumer segments, which lie, on social media such as Facebook. Practitioners may define their targeting and positioning strategy based on the newly formed consumer segments. Practitioners and researchers may directly create and use consumer segments through social media behaviour of the consumers.

This paper discusses the knowledge management practice (KMP) which is an important mechanism in the present-day scenario to enhance the organisational performance. The prime objective of this paper has been coined in the above line of thought and examines the importance of the KM enablers in the implementation of KMP model in manufacturing industry through the perspective of executives. In this regard, data were collected from 200 executives from 24 different types of manufacturing industries in Tamil Nadu, India through structured, validated and standardised questionnaire. The results from one way ANOVA and Pearson product moment correlation technique clearly showed the significant role of KM enablers in the knowledge management practice. Further, the data fit of this study also has been confirmed through structural equation modelling approach.
