Well, many sources on the web:

a/ printed circuit boards are etched by selective corrosion (Ferric Chloride corroding copper)

b/ many model engines and coaches are etched from brass sheet by selective corrosion

c/ Slightly different tack: stressed members in a vehicle body / chassis will selectively corode faster than unstressed ones

Let google be your friend and search a bit
