摘要：

Low temperature nitriding of stainless steel leads to the formation of a surface zone of so-called expanded austenite, i.e. by dissolution of large amounts of nitrogen in solid solution. In the present work the possibility of using nitrogen expanded austenite "layers" obtained by gaseous nitriding of AISI 316 as substrate for DLC coatings are investigated. Corrosion and erosion-corrosion measurements were carried out on low temperature nitrided stainless steel AISI 316 and on low temperature nitrided stainless steel AISI 316 with a top layer of DLC. The combination of DLC and low temperature nitriding dramatically reduces the amount of erosion-corrosion of stainless steel under impingement of particles in a corrosive medium.
