30 hp - Tribological properties of thin film coatings for powertrain applications

Introduction
Thesis work is an excellent way to get closer to Scania and build relationships for the future. Many of today's employees began their Scania career with their degree project.

Background
Scania is pushing the limits of our current products and surface technologies are required to provide solutions where regular surface treatment processes are no longer able to provide the required performance. Thin film coatings are being used more and more by Scania and there is a need to understand how different coating chemistries behave in operating conditions to provide proper solutions in the future.

Objective
The main objective is to describe wear mechanisms, and to provide wear and friction data for five different coatings which have different chemistry (DLC and Inorganic)

Job description
The thesis is highly experimental. The student shall:

• Develop a testing method for wear and seizure testing in a tribometer.
• Investigate wear properties of the different coatings in lubricated conditions.
• Analyse the friction behavior of all the coatings
• Investigate the wear mechanisms of each coating (Optical microscope, SEM, etc.)
• Determine which coatings are more suitable for powertrain components (gears, sliding joints, sliding bearings, etc.

Education/program/focus
Indicate education, program or focus: Engineering, mechanical, materials.

Number of students: 1

Start date for the thesis work: January 13th, 2025
