Vacuum Bonding for Extreme Wear Applications
CoorsTek proprietary vacuum-bonding process chemically locks small ceramic tiles to a structural substrate.
Vacuum bonding provides opportunities for custom designs that are not available with hard-facing or coatings. The ceramic used is a fully-dense, fired body, not a porous flame-sprayed coating. By using small tiles rather than a continuous coating, the blade can flex and twist with no damage to the individual tiles.
Advanced vacuum bonding technologies for:
- Fan blades
- Mixing paddles
- Screw conveyor components
- Piping components
- Cone linings
- Cyclone linings
- Impact panels
A major advantage of structural bonding is its compatibility with a large number of materials. If a particular application is so abrasive that aluminum oxide just won’t hold up, the high-wear areas can be inlaid with tungsten carbide, fine-grained silicon carbide, or a variety of exotic new materials. By limiting the use of exotic materials to the most severe wear points, the cost and weight of the blades is kept under control. For weight-sensitive applications, bonded-composites may offer a cost-effective solution. While steel remains the material of choice, a much lighter system can be built using aluminum substrates. This provides both a lighter-weight structure and a much stiffer blade.
