What is carburizing heat treatment process?

What is carburizing heat treatment process?

Carburising, carburizing (chiefly American English), or carburisation is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder.

What are the properties of heat treatment?

Heat treating is often used to alter the mechanical properties of a metallic alloy, manipulating properties such as the hardness, strength, toughness, ductility, and elasticity.

What are three types of carburizing?

There are three types of carburising commonly used:

  • gas carburising.
  • liquid carburising (or cyaniding)
  • solid (pack) carburising.

Why do we use carburizing?

Corrosionpedia Explains Carburizing The purpose of this process is to make the metal harder and manageable. The hardness of steel with low carbon content can be enhanced through the addition of carbon under a certain form of heat treatment. When successfully performed, it can improve the surface hardness of the steel.

What are the effects on different materials after heat treatment process?

The temperatures metals are heated to, and the rate of cooling after heat treatment can significantly change metal’s properties. The most common reasons that metals undergo heat treatment are to improve their strength, hardness, toughness, ductility, and corrosion resistance.

How do you classify the different heat treatment processes?

Various heat treatment processes can be classified as follows:

  1. Annealing.
  2. Normalizing.
  3. Hardening.
  4. Tempering.
  5. Case hardening.
  6. Surface hardening.
  7. Diffusion coating.

What is carburizing temp?

Carburizing is one of the most commonly performed steel heat treatments. The carburizing furnaces are either gas fired or electrically heated. The carburizing temperature varies from 870 to 940 ºC the gas atmosphere for carburizing is produced from liquid or gaseous hydrocarbons such as propane, butane or methane3.
