Transmission gear protection from rust
giugno 18, 2025
How to ensure transmission gear protection from rust?
Do your transmission gears work outdoors, exposed to rain, humidity or salt spray? Then transmission gear protection from rust is a topic you cannot ignore.
When steel and atmospheric agents meet, the risk of oxidation is very high. In just a few months, gears, flanges or bushings can seize or break. To avoid this, it is essential to choose the protection strategy that best suits your application.
Surface treatments for transmission gear protection from rust
Galvanic or protective treatments — such as zinc plating, phosphating or hard chrome plating — create a barrier against corrosive agents. This technique is economical and often effective, but can show its limits in the event of abrasion or wear.
Technical oils and greases: a temporary defense against rust
Oiling the components is a simple and widespread solution. However, transmission gear protection from rust is only guaranteed as long as the protective film is present. When the oil evaporates or is removed, the risk returns.
Advanced solutions: stainless steel and coatings for aggressive environments
For highly critical applications, you can opt for stainless steels or special alloys. Painted coatings can also offer good protection, as long as the components are not subject to movement or direct wear.
Strategy for protecting transmission parts from rust
Each situation requires a technical analysis. There is no universal solution: what matters is evaluating exposure, work cycles and duration. Only in this way can you guarantee reliability and longevity for your transmission parts.
Preventing corrosion is a strategic choice to increase the useful life of your components. And you, what solutions do you adopt to protect your transmission parts?
