Pit Repair

Pitting corrosion causes the appearance of small, shallow holes of metal surfaces, and this is a problem because it leaves behind empty holes where there used to be metal. Because these holes are shallow, they do not usually break all the way through the metal piece, but they allow cracks to start more easily, so it is important to learn how to repair pitted metal surfaces.

Pit Repair TEK8 Student Handout

The student handout will be given to all students working on the design challenge. It gives a brief recap of the story, it helps the students identify what they are attempting to achieve, and it recaps the design process.

Pit Repair TEK8 Facilitator’s Guide

This Instructor’s Guide provides the instructor additional information on how to run the design challenge with alternatives for materials and test setups as well as information to help make the design challenge a good educational experience.

Telling the Story Video

The Telling the Story Video conveys the societal impact of the student’s research that is the basis for the design challenge and will set the problem-solving context for students.

Design Challenge Video

The Design Challenge Video leads students through the design process. It indicates materials available, states what the criteria are for success and any constraints. It also gives a second ‘level’ of the design challenge that allows ‘early completers’ to move on to a slightly more difficult challenge.
