aluminum vs. steel in brake disc
Could someone give me the basics in beginning to analyze this? I am just now taking thermo and haven't taken structures and properties of materials yet.
I know I need to know the conductivity within each of the metals and to the air (same or not the same?). I need to figure out not just the melting point, but the temperature at which it begins to warp or fail in any way. I couldn't find any properties other than for room temperature here or elsewhere.
I realize the question of a brake rotor has many other complicating effects with the rotation and forces applied by the pad, and probably other things i am too unlearned to realize! I appreciate any advice as to what to neglect and to take into account.
Also, is there a simple answer to quantify the effects of anodizing and heat treating?
Thanks so much for any tips.
