THERMAL SPRAY COATINGS
At MBI we utilize the most advances metal spray systems of all types to apply engineered coatings for design or repair of various components. Our processes include HVOF, Plasma, Twin wire arc spray, powder flame spraying, wire metallizing, spray & fuse and more!
Thermal spraying is a process (using a metallizing gun) where a powdered material is fed into an intense concentrated flame, melted, streamed, would become atomized, then propelled onto a surface to become a coating. (Of course, the surface is properly prepared with the necessary masking and etching/grit blasting).
| Coating group-ati gr (sampling) | Average Hardness | General Applications areas | Typical properties & applications |
|---|---|---|---|
| Nickel-chrome alloys | 48 Rc | General build-up material | General machinable coatings with excellent oxidation resistance to temperatures up to 1500 deg F. |
| Nickel-Chrome- Boron-Si alloys | 60 Rc, variable | Dense, hard, oxide free | Resist abrasive grains, vavitation, particle erosion, corrosion resistant. Cams, Wear Rings, Exhaust Fans, etc. |
| Tungsten Carbide alloys | 72 Rc | Hard-coatings that are dense, without porosity. | Extreme wear resistance. Mixer blades, Fan blades, etc. |
| Cobalt alloys | 55 Rc | Hard-facing | High hot hardness. Resistance to wear by abrasive grains. |
| Ferrous alloys | Variable | General build up coatings | Heavy build up and repair work |
| Carbide alloys | 72 Rc | Hard coatings, dense low porosity | Extreme wear resistance. Mixer blades, Fan blades. |
| Plus many more! |
At MBI we use the latest technologically advanced equipment and proven materials /consumables from companies that are leaders in their fields such as Praxair, Sulzer Metco, Tafa, Eutectic, etc. There are hundreds of materials available to apply. Each and every coating material that we use is off-the-shelf researched and proven. Specific parameters are followed to reproduce the same coating over and over again with the highest repeatable quality anywhere.
These same processes and materials are produced to the most demanding standards, including aerospace, medical, gas turbine, petrochemical, automotive industries, etc.
From crankshafts to cutting edge golf clubs, MBI coatings are enhancing performance. Effective applications are being discovered and taken advantage off every day.
A Crankshaft is being Thermal sprayed to repair worn bearing and rod journals.
