The BYD Atto 3 is a popular electric vehicle (EV) known for its affordability and impressive range. However, there have been reports of rust issues in some of these cars, which has raised concerns among car owners and potential buyers. In this article, we will discuss the latest developments regarding the BYD Atto 3 rust issue and provide you with important information that you need to know.
The BYD Atto 3 rust issue is a problem that has been reported by some car owners who have noticed rust developing on their car's undercarriage, particularly in areas where water and dirt tend to accumulate. The rust issue seems to be more prevalent in areas with high humidity or exposure to salt, such as coastal regions.
The initial method of preventing rust was electroplating, which resulted in a gold-like appearance on bolts. This process was costly and required high electricity consumption. In the mid-90s, the more popular galvanization method was 'hot-dipped', which involves coating steel with zinc. Since then, most cars have been hot galvanized, reducing the issue of rust.
The hot-dipped method prevents rust by enveloping the steel in zinc, cutting off its access to oxygen, required for rust formation. Zinc is initially shiny but transforms into a dull grey hue due to zinc oxide formation, which further limits exposure to atmospheric oxygen and hinders rusting.
The third galvanization protection mechanism is called 'cathodic' protection. Zinc is a more electrochemically active metal, so it sacrifices itself to defend the steel. Adequate amounts of zinc are necessary to achieve the desired protection. Specifically, for every square meter of sheet metal, 70 grams of zinc per side are required.
Cathodic protection enables the steel to resist rust even when scratched, drilled, or exposed to other forms of localized damage, as the zinc layer provides electrochemical protection. In conclusion, galvanization is a reliable method to protect steel from rust, and cathodic protection offers additional localised damage resistance.
BYD has acknowledged the rust issue and has taken steps to address it, including improving the car's rust prevention measures and offering free rust repairs to affected customers.
