Flame spray
Flame spray is a unique and practical technique to apply a coating to almost any kind of metal and non-metal surfaces. This coating improves the basic material properties such as hardness, abrasion and scratch resistance and corrosion resistance.
Flame spray
Wear, erosion and/or corrosion of your machine park are inevitable. Often is overhauling much cheaper and faster compared to replacing. Flame spraying is a widely used technique for overhauling. With flame spraying a metallic coating is applied with the desired properties. The metallic coating is finished to a thousandth mm thinnest, exactly in accordance with the specifications.
With flame spraying you avoid unnecessary replacement and downtime of your machinery.
When to use flame spray?
Flame spray coatings are mainly used for:
- Repairing worn machine parts
- Applying a protective layer against wear and tear
- Increase of corrosion resistance
The flame spray process uses a metal powder or metal wire which is in various ways converted in a molten jet of particles that adhere very strongly to the substrate.
Applications
Flame spraying techniques
Electric wirespray
Electric wire spraying is a form of thermal spraying where two consumable metal wires are fed independently into the spray gun. With electrical wire spraying, coatings can be applied quickly and at low cost.
Autogenous powderspray
With autogenous powderspray, coatings have a homogeneous structure. These hot sprayed layers are well resistant to line, point and impact loads.
Autogenous wire spray
For corrosion protection, repairs or size corrections. The spray layers applied in this way are more or less impact or shock resistant. The structure of the layer is always micro-porous. This gives the ability to hold oil and thus self-lubricating properties are obtained.
HVOF flamespray
HVOF flamespray forms a coating with a high density and a high bonding value. The HVOF flamespray principle is based on a transfer of thermal and, in particular, kinetic energy from the spray particles of the substrate.
Plasma spray
The high heat level and conductivity of the plasma flame, in combination with the very high gas- and transport velocity of the molten particles result in optimal condtions for very strong adhesion, uniformity and purity of the sprayed layer.
Advantages of flame spraying
Stand time extension
Flame-spray coatings last 2 to 3 times longer.
Safer
Flame spraying doesn't distort or deform due to heat as other techniques.
Time-saving
A lead time of only a few hours is possible.
Cost savings
Repair costs a lot less than replacement.
