The present work focuses on, enriching the surface characteristics of the material rather than its bulk. The mild steel specimens were coated with molybdenum and molybdenum–silicon carbide composite coatings using HVOF technique. The developed specimens showed an enhancement in micro hardness and reduction in porosity. The enrichment of the microstructure was justified by subjecting the specimens to SEM and EDAX studies. There is an increase of hardness by 8% in the molybdenum coated specimen and by 23% in the composite coated specimen. © 2018 Elsevier Ltd. All rights reserved.

Introduction Metals play a vital role in our everyday life and are used to fabricate a wide variety of products. The variety ranges from paperclips to automobile engines. Metals have been a part of our civilization ever since Bronze Age. Copper was the first metal to have been extracted from the ore. But as copper is a rather soft metal it had to be combined with 2214 - 7853 © 2018 Elsevier Ltd. All rights reserved.
