Metal parts which undergo heat treatment and carburizing tend to resist abrasions more effectively, for instance. After this process surface hardness, wear-resistance and fatigue life are enhanced. At this temperature CO gas is produced which is a strong reducing agent. The oil quenching is used to minimize distortion when the components do not require much adjustment. For surfaces exposed to sand or other abrasives, nitrocarburizing provides abrasive wear resistance. The depth of diffusion (case depth) follows a time-temperature dependence such that: where the diffusivity factor, D, depends on temperature, the chemical composition of the steel, and the concentration gradient of carbon at the surface. While carburizing you quench from around 920C vs 830C when carbonitriding. This process is also called case hardening, and it adjusts steel to maintain its durability without removing properties that are also needed for a particular application. Heat treatment is the use of heat to modify the properties of a material, especially in metallurgy.Heat treatment is done via heating and cooling of substances. The hardness of a carburized exterior also protects sharp tools against chipping easily during normal use. In gas carburizing, commercially the most important variant of carburizing, the source of carbon is a carbon-rich furnace atmosphere produced either from gaseous hydrocarbons, for example, methane (CH4), propane (C3H3), and butane (C4H10), or from vaporized hydro-carbon liquids.
