Specialist laser cladding equipment reduces dust emissions
New laser cladding technologies allow for the manufacture of metal components, such as low-wear brake discs, with a significant reduction in fine dust emissions.
The powdered coating material is blown onto the workpiece and then melted by laser, so that it bonds metallurgically with the base material. This method creates more stable protective layers than hard chromium plating and new technologies have increased the process speed and reduced the thickness of the layers, with extremely thin layers of about 80 μm now possible.
Specialist supplier of welding, thermal spray and specialist laser cladding equipment, Weartech, says that the advantages of laser-coated brake discs are corrosion- and abrasion-resistant surfaces, reduced brake dust load and extended service life.
Laser-coated brake discs are not only suitable for current combustion engines, however, they will also be used in future electric vehicles, where brake discs will be required to meet specific standards for low particulate emissions.
Modern lasers can be used for a range of coating applications, including:
- Remanufacturing or repair welding
- Wear and corrosion protection
- Three-dimensional printing, or additive manufacturing
- Surface enhancement
- Coating of boiler tubes
- Coating of components in the oil and gas industry
Weartech offers a variety of products for use in wear, corrosion and hard-facing applications as well as maintenance and fabrication. Weartech recommends products best suited to a customer’s needs and offers in-house and on-site service, training and repairs.
