Overcoming Critical Cladding Challenges
How our gas-atomized Ni-based alloy powder addresses the most demanding engineering problems in high-temperature glass manufacturing and valve seat protection.
Porosity-Free Deposition
By implementing vacuum induction melting and advanced gas atomization, our powder features ultra-low internal gas content. This prevents the release of trapped gases during rapid cooling in laser cladding, delivering a completely dense, porosity-free protective coating.
Elimination of Sandholes
Strict control over oxide inclusions and trace element tolerances ensuring clean powder morphology. Slagging and non-metallic inclusions are minimized during deposition, preventing localized weak spots and sandhole defects in the finished glass mold edges.
High Thermal Fatigue Resistance
Glass molding requires repetitive thermal cycling up to 650°C. The precise balance of Boron and Silicon in our matrix helps form fine, evenly distributed borides and silicides, mitigating micro-cracking and resisting thermal fatigue during operations.

Frequently Asked Questions
Technical answers to support your transition from OEM powders to Daguang's equivalent alloys.
Can Daguang's Ni-based powder directly replace Metco 16C without parameters adjustment?
Yes, in most standard PTA and laser cladding setups, our Metco 16C equivalent matches the chemical composition range and melting characteristics closely. However, because laser absorption rates and powder flow rates can vary slightly depending on morphological distribution, we recommend a minor calibration test. Our technical team provides tailored parameters adjustments for your specific cladding machine.
How do you prevent cracking during the cladding of high-hardness (HRC 60+) Ni-based powders?
Cladding high-hardness self-fluxing alloys requires careful heat management. We recommend preheating the substrate (especially cast iron glass molds or carbon steel valve bodies) to 250°C - 350°C. Controlling the dilution rate by optimizing cladding speed and laser power is also critical to prevent stress build-up and subsequent cracking.
What particle sizes are available for different application methods?
We supply three standard particle size distributions: 15-45μm (high-speed laser cladding), 45-106μm (standard laser cladding), and 53-150μm (PTA cladding). Custom particle size ranges can be accommodated upon request through our screening and classification facilities.
What is the trial powder testing process for new customers?
New customers can request a 1-5kg sample via our inquiry form. We ship the sample with a batch-specific Certificate of Analysis (COA) detailing the composition and particle size distribution. Once received, our technical support engineers can assist you remotely to set up your initial cladding parameters.
