Mining and Analysis of In-use Vehicle Corrosion Data Based on Typical Environmental Conditions in China

Abstract

As an important performance indicator for measuring product quality and safety, vehicle corrosion resistance has always been of great concern to industry enterprises and consumers. In this paper, we collect, processed and analysed exterior corrosion data from a total of 54 in-use vehicles (the vehicle that has been licensed and put into service) of nine models with high ownership in the coastal region of North China. Through the evaluation model of automobile corrosion resistance performance, data mining analysis was conducted on five key areas and the whole vehicle with different brands and ages (3-year and 6-year vehicles), key areas including exterior body, passenger compartment, luggage compartment, engine compartment, and chassis. It was found that the chassis and engine compartment of each vehicle model were severely corroded, with the corrosion surface of some chassis parts reaching 100%. The luggage compartment and exterior body were slightly corroded, and the luggage compartment parts of 8 models have not corroded after 3 years of use.
