Definition - What does Resurfacing mean?
This is a surface treatment process that is done on components that require friction. It is used in creating grooves on rotors when they are relatively smooth, thus improves contact with the brake pads. It involves the removal of material to its original thickness. Therefore, it is useful for the removal of corrosion thickness layers from water-based metal components to correct lateral run-outs, tapering and parallelism.
Corrosionpedia explains Resurfacing
The process starts with sandblasting or any other technique like brushing that can be used to provide a surface for fillers (epoxy resin or liquid polymer composite technology). When the filler cures, a new layer is added to a certain thickness. The original thickness can then be achieved by machining the final component when it is fully cured and hard; CNC machines or milling machines are mostly used.
Resurfacing is done when the structural integrity of a component is wanting due to corrosion. After inspection of the component, research is required for the best material that can produce a secure bonding. Resurfacing is done on components that undergo corrosion and frictional wear. It is useful as a cost-effective method, compared to replacing components that have severe abrasion. It can also be applied in concrete or materials that are affected by corrosion.
