T1 - Fretting behavior of elastomer materials in hydrogen N2 - Safety and reliability are the major challenges to face for the development and acceptance of hydrogen technology. It is therefore crucial to study deeply material compatibility, in particular polymer materials that are directly in contact with hydrogen. This paper presents an experimental study on the fretting wear behavior of two types of cross-linked hydrogenated acrylonitrile butadiene rubbers against 316L steel ball in hydrogen environment. Furthermore, aging experiments were conducted for 7 days under static conditions in 100 MPa hydrogen. the influences of hydrogen pressure as well as the aging exposure on the fretting behavior are discussed by means of surface analyses along with the material properties.

Furthermore, aging experiments were conducted for 7 days under static conditions in 100 MPa hydrogen. Fretting tests revealed the wear of the polymer decreases with increasing hydrogen pressure. After high pressure hydrogen exposure, the fretting process is characterized by increased adhesion due to elastic deformation, leading to partial slip.

Furthermore, aging experiments were conducted for 7 days under static conditions in 100 MPa hydrogen and the physical and mechanical properties of the rubber materials were examined before and after hydrogen exposure. Fretting tests revealed that the wear of these compounds is significantly affected by the hydrogen environment compared to air, especially with NBR grades. After aging experiment, the friction response of HNBR grades is characterized by increased adhesion due to elastic deformation, leading to partial slip. T2 - 4th Int.
