Hey all, this is my first post on these forums so hello! I am doing an assignment at the moment and it is about the effects on mechanical properties of finishings and coating on metallic materials. I have been able to find info on hot dip galvanising and powder coating however i can't seem to find any info on how painting metallic materials effects it's mechanical properties. Hope someone is able to help me or point me in the right direction, i just need to find out how it effects (if it does) tenisle strength, impact, ductility, bend etc any info would be much appreciated guys!

 

Cheers Pete

None of the properties of the metal will be effected unless the surface coating is somehow incorporated into the crystaline structure of the metal, a process i am not even sure is currently possible. The object so coated may be stronger, less brittle or whatever but that is from adding the properties of the coating to those that are already in the metal, not from changing any intrinsic property of the metal inside. What does change is the average of those properties for the whole object. Think of it like an egg. The inside of the egg is no different whether the shell is there or not. The yolk is still soft, its only the shell (the coating) that is harder, more brittle, etc.

Hey mate thank you very much for your help!
