Precisely controlled laser beam
The process of laser cladding begins with a precisely controlled laser beam directed onto the substrate’s surface. This focused laser beam generates a localized, high-energy density heat source that melts the powdered alloy material. The alloy material is carefully selected based on the application requirements, ensuring optimal properties such as corrosion resistance, wear resistance, and thermal stability.
Minimized heat transfer
One of the key advantages of laser cladding lies in its ability to minimize heat transfer to the substrate. By focusing the laser energy, only a small area undergoes thermal exposure, preventing substantial changes in the substrate’s physical properties. This precision ensures that the original shape and dimensions of the substrate are preserved, crucial for maintaining component integrity and functionality.
Instant metallurgical bonding
Metallurgical bonding between the melted alloy and substrate occurs instantly as the molten material solidifies. This bond is characterized by its pore-free and crack-free nature, which significantly enhances the coating’s reliability and durability. The resultant surface exhibits superior properties compared to traditional coatings like nickel-chrome plating (NiCr) and high-velocity oxygen fuel (HVOF) spraying, making laser cladding an indispensable choice for critical applications.
