- Advantages of Thermal Spraying:
- Allows for precise application of coatings.
- Minimal heat input into the base material, reducing the risk of distortion.
- Suitable for large surfaces or parts that can’t be heated extensively.
Welding (Laser Cladding or PTA Welding)
In welding applications, the NiCrBSi powder is melted using a laser or plasma torch and fused directly to the substrate. This creates a metallurgically bonded layer that offers superior wear and corrosion resistance.
- Advantages of Welding:
- Creates a stronger bond with the base material compared to thermal spraying.
- The coating can be thicker, providing enhanced protection.
- Suitable for high-wear parts like mining tools and cutting edges.
Pros and Cons of NiCrBSi Powder Coating Techniques
