| Summary: | Innovation, leading to weight and cost reduction, is a key word concerning the design of steel auto body for auto
makers that aim to keep and improve their market share worldwide. On the other hand, auto body life, which is related
to the corrosion resistance of the materials employed, should always be considered. The latter has led the auto makers to
team up with suppliers to find the best solutions concerning the materials selection. The end result always points towards
different sets of steels either zinc-coated or zinc alloyed-coated. Taking all these aspects into consideration, the overall
challenge the auto makers face is to mitigate the time required for selection and narrow down the options available.
This paper studies the corrosion resistance of several materials applied on steel auto bodies using the technique named
spotface, which main advantage is reducing the time required by the traditional scribe to evaluate and compare different
materials, when they are submitted either to accelerated or field corrosion testing. Concerning the accelerated corrosion
testing, they were performed according to the General Motors do Brasil’s requirements. |
