Optimization of projection parameters
Optimizing thermal spray parameters can improve coating quality, increase process efficiency, and reduce production costs. This involves several aspects of the process, including temperature, particle velocity, gas pressure, and spray distance.
To expand as needed via a drop-down menu or gateway or other:
Reduction of porosity
– Better control of particle speed and temperature allows for denser and more homogeneous coatings.
– Improves mechanical and thermal resistance.
Better adhesion to the substrate
– Adjusting particle speed and temperature optimizes the bond between the coating and the substrate.
– Reduces the risk of coating delamination.
Reduction of defects (oxidation, cracking, inclusions)
– Spraying too hot or too fast can cause cracking or excessive oxidation.
– Precise control prevents the formation of microcracks and improves the durability of the coating.
2. Increased process efficiency
Best deposit rate
– Optimization of the parameters allows to increase the amount of material deposited on the part, thus reducing powder losses.
– Reduces the time needed to obtain the desired thickness.
Reduction of material waste
– Better atomization and jet control help limit the dispersion of unused particles.
– Reduces powder and gas consumption.
Optimization of energy used
– Properly adjusting the system power (flame, plasma, HVOF…) helps reduce energy consumption.
– Less energy lost as excess heat.
3. Improved coating performance
Increased thermal resistance
– Good spray control helps ensure more effective thermal barriers, essential for aircraft turbines and engines.
Better resistance to wear and corrosion
– A more uniform deposit ensures more effective protection against abrasion and oxidation.
Adaptability to industrial requirements
– By optimizing the parameters, it is possible to adapt the coatings to specific conditions (marine environment, high temperature, intense friction, etc.).
4. Cost reduction and productivity improvement
Less raw material used
– Reduced powder and energy losses, lowering production costs.
Save time in the process
– More efficient application means less rework and corrections after filing.
Better reproducibility
– Optimizing the parameters allows to obtain a consistent coating from one part to another, facilitating mass production.
