Thermal Spraying
HIGH TEMPERATURE PLASMA SPRAYING
- Ceramic and Cermet (Metal/Ceramic mix) coatings including: Chrome oxide, Aluminium oxide, Titanium oxide and Thermal barrier coatings such as Zirconium oxide
- Metal coatings including: Chrome carbide, Tungsten carbide and Alloyed steels
HVOF (HIGH VELOCITY OXYGEN FUEL)
** These are the most popular coatings for aggressive/abrasive environments
- Powders available including:
- **Tungsten carbide/Cobalt/Chrome (86-10-4) (Diatec 1086)
- **Nickel/Chrome/Boron alloy (Diatec 1060)
- (or Nickel/Chrome/Boron with Tungsten carbide matrix)
- Chrome carbide
- Tungsten carbide (various blends)
- ** Inconel 625 and 718
- Hastelloy, stainless steel, nickel (and almost any commercially available metal)
SPRAY AND FUSE WELDING PROCESS (SELF FLUXING ALLOY POWDER)
- **Colmonoy's 4,5 and 6
- Nickel,chrome,boron with self fluxing alloys
Note: **requires heat treatment after application on mild steel.
ELECTRIC ARC SPRAYING (TWIN WIRE)
Most alloys including:
- Stainless steels of various types, Carbon steels, Hastelloys and cored wires (various)
- Anti-corrosive wires including:
- Aluminium. Zinc, Monel, Copper, Aluminium bronze and Phosphor bronze
COMBUSTION SPRAYING (SINGLE WIRE plus POWDER LOW VELOCITY SPRAYING)
- Including Molybdenum, Copper, Nickel, Monel, Zinc, Aluminium, Brass
- Aluminium Bronze (good for anti-spark and protection against salt water corrosion)
- Various Stainless Steels and Nickel Alloys
Spray application Of Ceramics and Cermets
- Ceramics and Cermets can be applied using high temperature plasma spraying.
- Aluminium Titanium oxide, Aluminium oxide and Chrome oxide are just a few that are readily available.
We know of and can obtain more than 300 types of metal or ceramic coatings.
