Carbonitriding

Carbonitriding is a process where we make metal pieces stronger by putting them in a special room with gas. The gas is like a secret recipe that has both carbon and nitrogen. It's like adding extra ingredients to a cake to make it taste better. The metal pieces stay in the special room for a while, and the gas goes inside the metal pieces and makes them stronger.

Imagine you have a toy car made of metal, and it's not very strong. But you really like to play with it and want to make it stronger so that it doesn't break easily. You take the toy car to the special room and let it stay there for a while with the secret gas. After that, when you take your toy car out of the room, it's stronger and can handle more force without breaking.

Carbonitriding is a process that is used to make lots of things stronger, like gears, bolts, and even metal parts in cars and airplanes. It's a bit like a superhero power-up for metal pieces!
