Components
Aluminium Multi-Void Fin Tube
Aluminium multi-void fin tube for the cooling system allows the tube to be soldered when coated with Zinc.
Brakes Shoes & Disk Rotors
The engine system has seen the Metal/Thermal spray process solve a lot of issues, for example better performing and longer lasting brake components:
- Brake shoes suffer rapid wear but this is controlled when a plasma sprayed coating is applied making the shoes last longer.
- Improved brake performance, weight reduction and longer life is given to brake disc-rotors that suffer from an inconsistent friction coefficient.
Cam and Crank Shafts
Reclamation of cam and crankshafts using Plasma, Arc, Powder Flame or Flame Spray Equipment.
Car Panel Repair
Automobile body pressings are susceptible to various types of minor damage during production, handling and whilst creating sub-assemblies.
Metal Spraying using the Arc Process provides a fast, reliable and economic solution to repair these pressings.
Metal spray can be used in production repair of automobile body pressings and assemblies, including window frame joints, roof & quarter panel assy and roof & quarter panel sub assy to wings.
Cylinder Bores
Cylinder bores use plasma sprayed Molybdenum and Ferritic materials to eliminate the requirement of heavy cast iron linings.
Gear Box Reconditioning
Gearboxes are reconditioned using the Arc Spray process.
Gear Selector Forks, Clutch Disks and Synchroniser Rings
Gear selector forks, clutch disks and synchroniser rings suffer from wear so the application of a Molybdenum coating delivers high resistance to scuffing as well as constant friction coefficient for more precise gear selection.
Piston Rings and Crowns
- Piston rings have high wear resistance and less friction when coated with Molybdenum.
- Piston crowns gain improved engine efficiency and extended life when a thermal barrier coating is applied.
Steel Clutch Levers
Steel clutch levers can be reclaimed using the arc, powder flame or flame spray process.
Clutch Pressure Faces
Clutch pressure plate casting faces have been reclaimed by the arc spray process for well over 10 years, on a fully commercial basis, by clutch re-manufacturing specialists.
Gear Box Synchro Rings (Synchromesh Gears)
Gear box synchro rings are subject to considerable wear during the life of a tractor unit and David Brown Tractors Limited are using a Molybdenum sprayed synchro ring to improve the components resistance to wear.
The photograph shows on the right a synchro ring prior to metal spraying and on the left a synchro ring after metal spraying with molybdenum. Not only is the molybdenum extremely slow to wear but also it preserves its surface characteristics throughout its entire life. The metal spraying of these components is normally carried out on a continuous automatic plant using Plasma or Flame Spray systems.
Other sprayed components include, but are not limited to: turbocharger housings, valve guides and stems, shift forks, cylinder liners, engine blocks, connecting rods, exhaust sensors, alternator covers, exhaust pipes, shock absorbers.
