PhD position-Double degree– Green TRIBOS ESR 4

- Development of 3D printing multiphase self-lubricating filaments for low friction composite

Early stage researcher within Marie Skłodowska-Curie Joint European Doctorate (EJD) Training Network

Double degree PhD position at Luleå University of Technology(LTU), Sweden & University of Leeds, UK as a part of European Doctorate (EJD) Training Network – Green TRIBOS

Are you a rising star in the field of tribology, engineering materials or material science? Would you like to contribute to the development of cutting-edge technologies to impact on a green revolution in lubrication, friction and wear? Do you want to further your career and attain a PhD in one of the Sweden’s leading research intensive universities?

You will join a recently funded Innovative Training Network/European Joint Doctorate (ETN/EJD) GreenTRIBOS. GreenTRIBOS offers high-level doctoral training to a total of 12 Early-Stage Researchers (ESRs).  Three of you will be primarily based at and employed by Luleå University of Technology You will receive dual degrees with the Universities of Leeds/Coimbra/Ljubljana. GreenTRIBOS project coordinator is Prof Mitjan Kalin at the University of Ljubljana. 

ESR 4: Development of 3D printing multiphase self-lubricating filaments for low friction composites

Objectives: To investigate the effects of filler type and content on the tribo-mechanical properties of polymeric filament for the 3D-printing of a low-friction bearing To understand the effect of grapheme-based nanoparticles on the low-friction, self-lubricating behaviour of the composite filaments. To characterize the mechanical and tribological properties of the bearing prototypes.

Expected Results: Carbon-nanoparticles will be used as additive to improve the self-lubricity for the 3D printing of the bearing prototype and to understand the influential parameters affecting the prototype printing of different bearing types. With this, it will be possible to reduce the friction of the 3D-printed bearing with economic and environmental benefits through:


• Development of the new multiphase polymer composites for the 3D-printing of the bearing prototype
• Understanding the influence of various filament designs on the friction and wear of polymers
• Understanding the friction mechanisms of newly developed carbon-based, multiphase, nano-composites on an engineering scale

Department of Engineering Sciences and Mathematics at LTU: has knowledge, expertise and state of the art laboratory facilities to offer a broad interdisciplinary doctoral training education. Tribology is the main research focus at the Division of Machine Elements. The group is one of the largest tribology research groups in Europe with about 35 staff members (including 8 professors and 2 associate professors). This position belongs to the research subject Machine Elements.

Qualifications
You will have a top-class undergraduate degree and/or a Masters degree, or equivalent, in Mechanical Engineering, Polymer Science or Engineering or a relevant Physical Science in polymers, with research experience or an interest in Tribology, Materials and/or nanotechnology, and the flexibility to travel throughout the EU. Experience/knowledge in 3D printing of thermoplastic polymeric materials and knowledge in manufacturing of thermoplastic composites for loadbearing applications, material characterisation, polymer tribology and 2D based composites is meriting.

Important eligibility rules for this position 
There are no restrictions on the nationality, but


• Applicants must, at the time of recruitment, have not yet been awarded a doctorate degree and be in the first 4 years (full-time equivalent) of their research careers. This is measured from the date that you obtained the degree which would entitle you to embark on a PhD.
• At the time of recruitment, applicants must not have resided or carried out their main activity (work, studies, etc...) in the SWEDEN for more than 12 months in the 3 years immediately prior to their recruitment under the GreenTRIBOS project. Compulsory national service and/or short stays such as holidays are not taken into account. 

Salary
The Marie Sklodowska-Curie Early-Stage Researcher living allowance is fixed at 632 025 SEK per annum including the mobility allowance. This figure is before employer’s and employee’s deductions for national insurance and taxes per year, which will be paid in Swedish krona using an appropriate conversion rate.
