Hydrogen cracking of steels is a major concern in steel processing and service, and occurs in several applications, such as cracking of rolled steel products, cold cracking of welds, and as a result of corrosion in H2S environments.
Low-permeation thin films can be used as hydrogen permeation barriers. When coated on stainless steel they can reduce the rate of hydrogen transport. And they might be useful for sterling engines, tritium containment, or components of hydrogen fuel cells.
The hydrogen permeation behavior of BN-coated SUS316L stainless steel was investigated. The c-BN (cubic boron nitride) coating, deposited by magnetically enhanced plasma ion plating, was effective to reduce the rate of hydrogen permeation through stainless steel. The c-BN coating is also known as high-performance coating for cutting tools at high temperature.
This can be used for high-temperature and wear-resistant applications as hydrogen permeation barriers.
