  1. 1. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Diego Manuel Chamorro Ruz; [2022]
    Keywords : micropitting; nanoadditive; gear; bearing; tribology; rolling contact fatigue;

    Abstract : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. READ MORE

  4. 3. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Zapata Tamayo Juan Guillermo; [2021]
    Keywords : micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

    Abstract : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

  5. 4. Evaluation of 25 MHz Ultrasonic Testing for Detection of Non-Metallic Inclusions in Steel

    University essay from KTH/Materialvetenskap

    Author : Henrietta Isaksson; [2021]
    Keywords : Ultrasonic Testing; High Frequency Ultrasonic Testing; Quantification of inclusions; Fatigue Testing; Ultraljudstestning; Högfrekvent ultraljudstestning; Kvantifiering av inneslutningar; Utmattningstestning;

    Abstract : Quantification of inclusions is important since it is correlated to the steel’s fatigue properties. One method that could be further developed for detection of inclusions in steel is ultrasonic testing (UST). READ MORE
