What is adhesive bonding and what its advantages and disadvantages?

Answer 1

Adhesives can be used to attach two separate items, or 1 item that broke into two pieces or 1 item that has ripped.

Depending on the circumstances, having the right adhesive at the right time could save lives--literally. An example: if a person had a sucking chest wound, an adhesive could be used to secure an air-tight barrier to the wound, allow the victim to breathe.

It could also be very helpful for improvised car or bicycle repair--allowing a person to travel a few extra miles and reach a service station.

Adhesives can help a person save money too. One can make temporary repairs (say, to the sole of your shoe if it came unattached to the rest of your shoe). If you had a really good adhesive, you might be able to use those shoes for another year or two.

A disadvantage of adhesives is that some are so powerful that they can injure a person unnecessarily. Even some bandages that initially helped a person heal, could cause extra wound when trying to remove the bandage. It can also re-open a wound.

If someone was trying to improvise a repair (car or bike), and they were sloppy with the adhesive, they could cause more, unncessary damage. For example, let's say a person was super gluing his hand grips on his bike, and dripped some glue on his sprocket and chain-links.

Answer 2

Adhesive bonding is the gluing together of different wafers. An advantage is that the materials can bond together at low temperatures. However, they may not fit together perfectly, leaving each layer vulnerable.
