The AvaC® process is a technology exclusive to Ipsen that uses acetylene to virtually eliminate the soot and tar formation problem known to occur from propane, while greatly increasing carburizing power even for blind or through holes.
One of the most important advantages of the AvaC® process is high carbon availability, ensuring extremely homogenous carburizing even for complex geometries and very high load densities. The AvaC® process involves alternate injection of acetylene (boost) and a neutral gas, such as nitrogen, for diffusion. During boost injection, acetylene will only dissociate in contact with all-metal surfaces allowing for uniform carburizing.
The most remarkable benefit to AvaC® can be found when the different hydrocarbon gases for low-pressure carburizing are evaluated for their penetration power into small-diameter, long, blind holes. Vacuum carburizing with acetylene results in a complete carburizing effect along the whole length of the bore because acetylene has a totally different carburizing capability than that of propane or ethylene.
