Gaseous carburizing is the most widely employed carburizing process. The carbon needed for diffusion is derived from a gaseous furnace atmosphere produced either from hydrocarbons such as methane, propane and butane or from vaporized hydrocarbon liquids.
Gaseous Nitriding is a surface hardening process in which nitrogen is allowed to diffuse into the ferrous components. Gaseous Nitriding is the earliest form of Nitriding which is still used in a large measure today.
Normalizing is a process in which the material is heated in an atmospheric furnace to a temperature just above the upper critical line of the iron-iron carbide phase diagram. The actual temperature varies by alloy but is typically around 1600 ° F.
Salt Bath Nitriding
Salt Bath Nitriding is a ferritic nitrocarburizing process which involves the diffusional addition of both nitrogen and carbon to the ferrous surface at temperatures within the ferritic phase. This process is preferred for improving tribological and surface properties of ferrous components in addition to improving fatigue strength.
Thermal spraying is an overlay process and materials used for spraying are principally in the form of powder, rod or wire. Thermal spraying usually consists of pre spray treatments and sometimes post spray treatments.
Vacuum Heat Treating
Our Abar Ipsen H4848 furnace is a two bar quench, with high vacuum capabilities that reach the .1micron range. The round internal heating zone allows us to process large or odd shaped parts.
