Looking at the following claims properties of alloys are superior to the properties of pure metals.

I need to come up with a scientific research question
Please help me
This is what i've wrote but teacher told me it was very broad..
Due to the different properties anti-corrosive properties of metals than pure metals since these properties are beneficial for use of construction focusing on dry and we corrosion?

Are alloys suitable to use in the building and construction industry since they are more corrosion-resistant than pure metals, which makes them useful as tools and construction materials?

Are different anticorrosive properties of alloys than pure metals, these properties are beneficial for the use of both dry and wet corrosion in construction?

Is this a research question you will need to follow up on? If so you want to pick one that you can easily follow though. I don't know how much time you have to do this work or even if you must do the work but you might have question like this.

Which alloys show corrosion resistance better than metals.
Then if this becomes a writing assignment you use the library, Google, the Internet, any books you have or can borrow. do all that reading then write a paper on what you found in the literature.
If this a a lab thing you get some pieces of different metals (Cu, Ag, Pb, Al,etc) and different alloys (different stainless steels, brass, bronze, etc) and set up an experiment so these metals and alloys are bathed in air and anothr one where they are bathed in water. Each day you observe and at the end of a certain time you write a report on the results. (Remember there are MANY different kinds of stainless steels.)
I hope I've helped but I may have not hit the mark. At any rate, I have given you some idea and you can spin off that. Good luck.
