Carburizing and nitriding generally refers to surface chemical heat treatment of steel.

Carburizing must use low-carbon steel or low carbon steel. It can be divided into solid liquid gas carburizing three. The wider application of gas carburizing, heating temperature 900-950 degrees Celsius. Carburized depth depends on the holding time, generally based on estimates 0.2-0.25 mm per hour. Surface carbon content of up to 0.85-1.05 percent. After the carburizing Induction heating sintering furnace shows the effect of sintering furnace sintering mainly plays: press-molded powder material at high temperature below the melting point, by body mutual adhesion between the particles and mass transfer, so that the pores excluded, volume shrinkage, strength is improved, the process of becoming a certain geometry and strength. href=”http://www.vacfurnace.com/vacuum-furnace-product/vacuum-heat-treatment-furnace/”>heat treatment must, after quenching and tempering commonly used. To give high surface hardness and high toughness core part wear impact parts.

The surface of the aluminum and steel nitrogen atoms of chromium molybdenum nitride is formed, the general depth of 0.1 to 0.6 mm, the nitride layer can be obtained without quenching high hardness, this performance can be maintained to 600-650 degrees Celsius. Small deformation of the workpiece prevented. Corrosive alkaline solution of water vapor. But the long production cycle, high cost, nitride thin and brittle, should not bear the focus of heavy loads. Mainly used to deal with important and complex precision parts.

Coating, coating, a physical method. “Infiltration” is the chemical changes, essentially different.
— Carburizing steel is heated in the low-carbon steel carbon-rich medium to high temperatures (typically 900–950C), so that the activated carbon atoms into the steel surface to obtain a nitrided layer of high-carbon. Followed by quenching and tempering, the surface with high hardness, wear resistance and fatigue resistance, while the core part remains sufficient strength and toughness.
