Industrial Lubrication and Tribology

Industrial Lubrication and Tribology provides a broad coverage of the materials and techniques employed in tribology. It contains a firm technical news element which brings together and promotes best practice in the three disciplines of tribology, which comprise lubrication, wear and friction. ILT also follows the progress of research into advanced lubricants, bearings, seals, gears and related machinery parts, as well as materials selection. A double-blind peer review process involving the editor and other subject experts ensures the content's validity and relevance. The journal aims to help industry professionals to reduce the loss caused by friction-related downtime, as up to 50% of machinery is at a standstill at any one time as a direct result of a lack of or improper application of lubricants. Determining which lubricants work best in different types of machinery—and understanding how and why—can have far-reaching effects in areas such as costs, productivity and quality. ILT places special emphasis on the development of alternatives to finite hydrocarbons, including synthetics, ‘dry’ lubricants, plastics composites and innovative carbon materials. This leading-edge material, drawn from both academic and industrial sources, plus a unique rolling programme review of new products and developments, means that ILT is a balanced and well-informed resource offering immediate practical advantages to its subscribers. • Abrasion resistant materials • Advanced lubricants • Advanced surfaces • Biotribology • Carbon-based materials • Condition monitoring • Green tribology • Lubricant additives • Oil refining • Surface texturing • Wear-resistant coatings.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
