Math is not local, it is universal. Your question is incoherent.

A glass pearl has a round glass bead under the pearl coating. A Swarovski pearl has a round Swarovski crystal bead under the pearl coating.
There are both fundamental differences, and relationships between these two gives. Stainless steel is an iron based metal alloy. Teflon is a trademarked synthetic chemical used as a nonstick and lubricating coating, often on metal surfaces.
The active ingredient in both, ibuprofen, is the same. What is different is the coating, shape of the pill, bindings and other inactive ingredients.
Epoxy-polyester powder coating is a hybrid of epoxy and polyester powder coating, and galvanised is coating thickness for steel bars and components is between 3 and 4 mils.
The difference between the conventional coating and film coating depends with the material used. The film coating uses a film to coat while the conventional coating does not use any type of material to coat.
Powder coating is free-flowing, dry powder. It differs from regular paint in that paint requires a solvent while powder coating does not. The coating is usually applied electrostatically.
Pipe Lining refers to the internal diameter, pipe coating is external.
The M&Ms are not actually different flavors. They are all chocolate flavored with colored sugar coating.
Powder coating is a substance used for the coating of items such as household appliances, drum hardware, and vehicle parts. The difference between this type of coating and liquid paint is that the powder does not require any solvents to bind to the materials. Powder coating is the process you use to apply a coating without using solvents. This is the newest coating technique in the industry right now. You usually apply this type of coating to create a hard finish on metals and because it allows you the flexibility to apply to a different layer of thickness. You would see this finishing in materials such as aluminium, medium density fibreboards, fusion-bonded epoxy and acrylics, usually on automobile finishing.
painting is application of color to a surface and can be use for aesthetic use coating is application of to protect the underlaying surface such as FBE coating and meatal coating and powder coating
If you're referring to the colored coating on some blades....that's all it is (same for the rainbow or blue ones). I'm not sure how it's applied -- probably a chemical bath...it DOES come off over time (or with the deburring wheel on a bench grinder). It's purpose is as a rust protection while sitting in the controlled environtment of a warehouse between manufacture and initial sale to a vendor. If the coating has not been applied, the blade is covered in a grease coating for the same reason (but it's more of a pain to get off) The coating does nothing to the flexibility or longevity of a blade...THAT is handled during the forging/manufacture process. Maraging blades ARE different from regular blades, but that's a matter of different metallurgy, not the color coating.
