摘要：

Rail transportation has been one of the most efficient and sustainable means of mobility with large economic value. The rail wheel flange steers on the rail track for motion with imparts of frictional force and rotational speed. High temperature is generated and prolific wear at high speed which is reduced by lubrication. Additive manufacturing techniques of laser cladding of steel rail surface were employed in this study with the ceramics of Titanium and Titanium boride powders at different mix ratio on steel rail surface. Different metallurgical characterization of cladded surface was carried out. The best hardness and microstructural view were noticed at 50:50 mix ratio of the cladded ceramics. The phase transformation of the varying mix ratio was also revealed. (C) 2019 The Authors. Published by Elsevier B.V.
