MagnaTech has just completed a Department of Defense Phase I Option Contract. The contract required continued development of a carburizing process or development of a carbonitriding process to provide a martensitic stainless steel with a hardened surface greater than 58 HRC for a depth of hardness of 1 mm (0.040 inch). MagnaTech has accomplished this objective. Further testing for wear resistance has shown that the resistance to abrasion by sand at a given load is three times greater than the present Metco 12 C hardfaced surface. In addition, the corrosion resistance in a salt solution is comparable. MagnaTech has applied for patent protection to protect the developed process and is currently awaiting a decision by the Patent Office. MagnaTech has a similar process to nitride martensitic stainless steels and has also applied for patent protection regarding this process.
MagnaTech has submitted a proposal for continuation of the development to improve wear and corrosion resistance of hook points for landing gear of navy aircraft. If granted a Phase II contract, MagnaTech will extend the work to determine whether the process can be applied to low alloy steels and also scale up the process to carburize surfaces of wear resistant components to satisfy production requirements. If granted, the research will involve a two year effort and will lead to production of martensitic stainless steel parts requiring surface modification for enhanced wear, particularly from abrasion, under adverse environmental conditions.
MagnaTech is currently contacting companies that require hard, wear resistant surfaces to determine whether the process can be of advantage for their applications.
