Summary for car corrosion prevention Discussion
Corrosion prevention of car bodies and components has improved a lot over the last 20 years, according to the answer. The main advances named were galvannealed steel, electrophoretic primers, better nickel-chrome plating verified by the STEP test, and replacing some metal parts with plastic. The reply also noted wider use of stainless steel for systems such as exhausts, zinc-alloy plated fasteners, and mounting trim with adhesive or plastic barbs instead of metal bolts to reduce corrosion points. Looking ahead, the answerer said the trend will probably continue toward more plastic, stainless steel, and aluminum, though that was presented as a layman’s guess rather than an insider forecast. The question itself asked how to search for corrosion prevention methods and how they have improved over the past two decades.
Q. I am Yee Chin from Malaysia.now take the summer holiday course in Sheffield Hallam university (Materials and manufacturing Engineering). My question are:1) I need to search corrosion prevention of car. 2) how to improve the prevention ? and 3) the improvement already done of corrosion prevention of car during this
20 years.
I hoped that I can get your help as soon as possible; thanks a lot; have a nice day. Bye

A. Some of the major elements of the progress were the use of galvannealed steel, electrophoretic primers, improved nickel-chrome plating via the STEP test, replacement of some parts with plastic, use of stainless steel for some systems like the exhaust system, zinc-alloy plated fasteners, and mounting the trim with adhesive or plastic barbs instead of bolting it with metal bolts.
The future probably includes more use of plastic, stainless steel, and aluminum–but this is a layman’s guess, not an insider’s plan.
