Is Surface hardening better method to use or Annealing when these methods are used to manufacture products from ferrous metals?

These are two different methods that are opposites. Surface hardening is used to stiffen a steel. Usually a steel is heated, a catalyst is applied to the surface and then the steel is quenched in an oil bath or waterbath, this hardens the surface of the steel. Annealing on the other hand, the steel is heated and then allowed to cool slowly. This softens the steel and allows it to be drawn or hammered to form a different shape.

Why when a thin layer of water flows along an inclined gutter different wave patterns are sometimes observed?

because water has a surface tension that likes to hold together. How much it takes to hold it together is based on what incline it is on. In this case, wave patterns are observed because the surface tension keeps a larger amount of water in one place, until the weight overcomes the surface tension, and it creates the wave pattern you see.
