Gears are a crucial part of many machines, and if they wear and corrode beyond repair it can then be a costly expense to replace them. Mark Meyer, Sales Manager, North America at SIFCO ASC, explains how brush plating can help prevent gears from being damaged and how the process can be used to restore worn or corroded gear components.
No matter how well gears are designed and manufactured, gear corrosion can occur that may easily result in catastrophic failure. Since corrosion is a sporadic and rare event and often difficult to observe in the root fillet region or in finely pitched gears with normal visual inspection, it may easily go undetected. This paper
presents the results of an incident
that occurred in a gear manufacturing
facility several years ago that resulted in pitting corrosion and intergranular attack (IGA).
