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.

What is case hardening?
Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy.
Define the material of grit in grit blasting?
The grit is chosen to be suitable for the job in hand. It must be hard/abrasive enough to remove whatever is contaminating the surface, but soft enough not to damage the surface underneath. At one extreme you might use corundum or silicon carbide, at the other, products such as ground cork or walnut shell are used.
Effects of built-up edge on tool wear?
I would say that it's good for the tool wear because the built up edge it's like a coating which protect the tool. Possibly move the tool wear. But it's bad for the skin of the piece (poor surface finish), and you don't have dimentional control (temporarily change the global shape of the tool), you over heat the piece and work hardening. To summarize, try to avoid it (increase speed and lubricant).

How is a roller-bug used to lay concrete?
for sure it affects the surface to a certain limit as you increase the paste on the surface and decrease the aggregat amount which may lead to surface abbraision...using surface hardner will help to strenghten the surface.
Why Strength and hardness of material are decreased by annealing?
because it removes the tempering(hardness) of the object, generally on the surface, and makes it easier to work the metal without ruining your tools or "work" hardening the surface.
How does surface hardening different from true hardening?
in my opinion surface hardening is applied only on the surface while the true hardening is applied in the whole part of the metal....
What exactly is case hardening?
Case hardening, also referred to as surface hardening is the process of hardening a surface of a metal. It is done by surfacing the metal surface with a layer of metal on top of it, in order to harden it.

How you can increase melting point of aluminium?
To increase the melting point of aluminium, (and treating this as a philosophical question), then hardening the 'crystal matrix' may be one approach. Surface hardening by work hardening, or perhaps by inserting nitrogen ions into the surface as is used in metal(ferrous) hardening.
