LAB 1G Sometimes tools such as drill bits and saw blades are coated with very hard compounds to increase their durability and cutting performance. Based on your extensive understanding of electro-negativity and bonding, please rank the following coatings in terms can all be deposited on the steel tool equally well). Additionally please justify your assertions and please comment on which properties would be important for the ideal tool coating of suitability for use as a tool coating (assume they Silicon Nitride (SiN) Zirconium Oxide (ZrO2) (CZ for the thugs in the audience) Titanium Nitride (TiN) Zirconium Nitride (ZrN) Silicon Carbide (SiC)
