Hyper baric carburising process

Anew patented technology improves low pressure carburising in vacuum furnace and traditionalcarburising in sealed quench furnace.The author, starting from argument that is possible to see in the specialized publications on the subject,has examined by scientific criteria which are the limits and the advantages of both the low pressurecarburising ,or the controlled atmosphere process. He evaluates the technological possibility to overcomesome of the limits that are conditioning the mechanical property of the heat treated pieces. Beforesuggesting new technological solutions that can promote better metallurgical properties together withclean environment, he examine some scientific arguments to make clear the problems.At the end of this research some important technological modification will be realised and the obtainedresults confirm the validity of the new process of hyper baric carburisation.The cause of the defects arising from the traditional technology have been eliminated and themodifications requested on the furnaces are not expensive. In same cases, maybe the new furnaces areeven cheaper, both in the buying phase than in the running cost
