Change is still a good thing!

Dr. Robert Gresham, Contributing Editor | TLT Lubrication Fundamentals June 2019


Last month I wrote on some of the changes I had seen in our society since joining as a member in 1981 and later serving as part of the staff. I was mostly concerned with the changes resulting from our efforts to become an international organization. As a consequence of some of those changes, we also became a better society for our individual industrial members and our corporate members. Read Full Article .



Self-healing coating to prevent corrosion

Dr. Neil Canter, Contributing Editor | TLT Tech Beat June 2019


New techniques for inhibiting corrosion are needed because of the challenge in detecting this phenomenon as it initiates in a specific location. Once localized corrosion starts, it can be difficult to detect and stop what potentially can lead to catastrophic failure of a specific machine. Read Full Article .

Five-Stage Selection Procedure of Ionic Liquids for Lubrication of Steel-Steel Contacts in Space Mechanisms

By Nicole Dörr, Andreas Merstallinger, Roland Holzbauer, Vladimir Pejaković, Josef Brenner, Lucia Pisarova, Julia Stelzl, Marcella Frauscher


An experimental approach using the stage-gate process is presented to efficiently select and assess ionic liquids (ILs) for their usability in space mechanisms, thus, for their potential to replace commonly used liquid lubricants based on perfluorinated polyethers and multiply alkylated cyclopentanes. This methodology was based on a five-stage selection procedure comprising the determination of rheological properties, outgassing properties, corrosion-inhibiting capabilities, screening of friction and wear performance in vacuum, which was completed by tribometrical lifetime assessments. Five ILs were benchmarked against Fomblin® Z25 as reference at the end of each stage and selected for the next stage depending on the performance. One IL of the type pyrrolidinium bis(trifluoromethylsulfonyl)amide outperformed Fomblin® Z25 in all stages except pour point. Thus, only in the case of fluidity at very low temperature showed Fomblin® Z25 a better performance. Additives slightly improved corrosion inhibition of this IL but showed adverse effects on friction and wear in comparison to the neat IL. In lifetime experiments, the IL resulted in a lifetime extension of at least factor 23 and 31 compared to the reference. Even with the use of additives in this IL, the lifetime extension was still by a factor of 6 to 15 compared to Fomblin® Z25. Read Full Article


Tribology Letters is devoted to the development of the science of tribology and its applications, particularly focusing on publishing high-quality papers at the forefront of tribological science and that address the fundamentals of friction, lubrication, wear, or adhesion.  The journal facilitates communication and exchange of seminal ideas among thousands of practitioners who are engaged worldwide in the pursuit of tribology-based science and technology.
