Abstract: Title: Mo-Reinforced Tungsten Carbide–Based Composite Cladding for High-Temperature and Wear-Resistant Applications Deposited by Laser Direct Energy Deposition The present invention relates to a molybdenum-reinforced composite cladding composition and a method for producing a protective surface layer through a laser direct energy deposition process. A tungsten carbide-based hard-facing alloy powder is reinforced with about 9 wt% molybdenum to achieve enhanced hardness and improved mechanical performance. The reinforced feedstock is homogenized and deposited onto a substrate to produce a dense, metallurgically bonded clad layer with minimal porosity and a refined microstructure. The developed cladding demonstrates enhanced hardness, improved elastic modulus, and reduced wear rates under dry sliding conditions. The invention provides an advanced composition-engineered cladding system suitable for high-temperature and severe-wear applications, including the repair and refurbishment of engineering components that require superior surface durability and extended operational life.
