Seal Failures and Measurement Failures - BC-333

Preferred Disciplines: Materials Science and Engineering, Chemistry, Physics, Welding Engineering, Mechanical Engineering, Masters, PhD or PDF
Project length: 8 to 12 months
Desired start date: May 2017
Location: Burnaby, BC
No. of Positions: 1
Preferences: Mechanical Engineering
Company: Mercedes-Benz Canada Fuel Cell Division

About Company:

Mercedes-Benz Canada is the Canadian subsidiary of Daimler AG, the world's oldest car manufacturer. Located in Burnaby, British Columbia, Mercedes-Benz Fuel Cell production facility is responsible for Daimler’s global production of fuel cell stacks – the technology at the foundation of alternative propulsion strategy.

Project Description:

The aim of this project is to characterize and assess existing welds, map locations and types of failures.   Leak testing of welds It also aims to characterize welds by existing

This project is multi-faceted.  It aims to characterize seal failures and document consequences.  It aims to develop a failure catalogue that could be used for pass-fail criteria.  It also aims to develop tools to identify and characterize failures, in particular, leak.  It also aims to develop or improve further a leak location device to better understand failures and causes in fuel cell components. 

Develop an interface to report a leak location results.  Tools can also be developed and validated for use in manufacturing and at suppliers.  A method to measure surface energy for non-flat surfaces will also be improved.  It will also be assessed and qualified for use in fuel cell manufacturing.  The influences of surface energy will also be further investigated.

Develop procedures, supporting documentations, measuring methods and gauge R&R, quality sign-off for all tools.

Background and required skills

Research Objectives/Sub-Objectives:

  • Definition of seal failure catalogue – correlation of component properties and seal data
    • Incoming component quality influence seals and seal manufacturability
    • Define/improve link between component imperfection and influence on seal geometry
    • Redefine specification for components to drawing requirements
  • Jigs for component testing
    • Existing leak location jigs to be assessed and see if any improvements can be made
    • Design new jigs
    • Literature research/state-of-the-art on alternative methods
    • Trials with new jigs and defined leaky components if these leaks could be observed
    • Assess whether the leaks are coming from seals
  • Tooling characterization

Methodology:

  • Define seal catalogue
  • Develop improved jigs possibly
  • Quality approach
  • Tool development and qualification

Expertise and Skills Needed:

  •  Sealing and failure measurements. Researchers can be in any discipline involved in the filed: Materials Science and Engineering, Chemistry, Physics Mechanical Engineering
