LaserBond’s reclamation and surface engineering technology improves resistance to wear and corrosion

Supplier News

LaserBond  can reclaim worn industrial parts at a lesser cost than of replacement. The resistance to wear and corrosion can be improved, and the performance enhanced. New replacement parts can be “surface engineered” to provide longer service life.

Following are the benefits of LaserBond’s reclamation and surface engineering technology:

  • Lower running costs
  • Minimised down-time and breakdowns
  • Reduced waste of high value materials
  • Increased productivity/up time, and
  • Reduced spare parts inventory

The reclamation and surface engineering technology processes involve low heat, extending the range of components that can be reclaimed and materials that can be applied. If customers cannot purchase or cannot do stock replacement parts for machinery, they can be rebuilt with the help of the technology. If the equipment is running longer between maintenance shutdowns, the surfaces of critical components can be engineered for longer life with cutting edge technology.

Following are the industries that use reclamation and surface engineering technology:

  • Steel making and processing
  • Pumping equipment
  • Valve equipment
  • Paper making and conversion
  • Timber
  • Mining and minerals processing
  • Rail transport
  • Trucking and road transport
  • Power generation
  • Water and waste water treatment
  • Aluminium making and processing
  • Plastics
  • Packaging
  • Toolmaking
  • Glass manufacturing
  • Automotive and motorsport
  • Concrete and concrete products
  • Building products
  • Printing
  • Aerospace
  • Pet food
  • Food
  • Marine
  • Defence
  • Agriculture

LaserBond achieve a welded bond with limited and precisely controlled heat input. Heat sensitive components, such as hardened shafts and gears can be repaired without risk of distortion or other undesirable heat effects.

The metallurgical bond allows LaserBond applied layers to be used in high impact and other heavily loaded situations. With this welded bond, LaserBond layer will not spall or separate from the component or substrate.

The controlled energy minimises the undesirable thermal decomposition of hard phases such as carbides, resulting in superior wear resistance. Due to the extremely low dilution with the substrate, high performance surfaces can be applied in a thin layer. Corrosion and wear resistant surfaces as thin as 0.3mm are possible. Heat affected zones are minimised and the cracking inherent in welded or PTA applied hard facing is typically eliminated.

LaserBond applied materials include Tungsten Carbide, tool steels, stainless steels, Nickel alloys such as Inconel and Cobalt alloys such as Stellite1, and copper and copper alloys. LaserBond system is flexible and can process small components up to large rolls of 1600mm diameter and 6m length. Hard to reach areas such as inside diameters and recesses (crankshaft pins) can also be repaired.

Large capacity lathes, grinders, mills and borers are all used to restore components to precise tolerances and required surface finishes. Superfinishing is attained with semi-automated equipment and precision diamond abrasives. Further, the workshop is set up for flexibility to handle a large range of components. However, if the equipment is too big to economically dismantle and transport, users can carry out thermal spray operations on-site using the trained and qualified operators from LaserBond.

LaserBond was previously known as HVOF and Laser Technologies.
