(d) By using the data provided below, calculate the PillingBedworth ratio for the nickel (Ni) – nickel oxide (NiO) system and determine whether NiO is protective against corrosion.  Atomic mass of nickel = 58.7 g.mol-1 Density of nickel = 8.91 Mg.m-3 Molecular mass of nickel oxide = 74.7 g.mol-1  Density of nickel oxide = 6.67 Mg.m-3 (e) A stainless steel pressure vessel that has fracture toughness, K1C, of 197 MN.m-3/2 is going to be exposed to a stress of 398 MN.m-2 . By using this information explain how designers can determine the thickness of the vessel so that catastrophic failure can be avoided.
