Wear analysis concepts & common wear types
Abrasive wear
Adhesive wear
Erosive wear
Cavitation erosion wear
Corrosion
Fretting corrosion
Contact stress fatigue wear
I learned the five basic wear analysis concepts which are :
1-observe surface features
2-identify wear type
3-observe wear location
4-list enabling conditions
5-determine what to do next to gather more facts
I learned that if you follow these steps you will find the reasons and places your parts have failed. If you pay attention to the wear type,surface facts will help you identify what type of wear it is. Then look at the location of the wear these things will help you think about possible problems with loading,alignment,clearances, and lubrication.
40 week
80 month
C 97%
I got a 92% on D only missing 5 problems
The areas studied in d were shorter and it covered the steps of wear condition.
Step 1 State the problem
Step 2 Organize fact gathering
Step 3 Observe and record facts
Step 4 Think with the facts
Step 5 Determine the root cause
Step 6,7, and 8 Get the payoff
I learned how to observe and determine wear conditions in parts and how to catalog parts for dis-assembly
Well reflected Jason.
ReplyDeleteThis is a lot of learning here. Failure analysis builds the roots of our troubleshooting process. I copied and pasted the following for me. We all need to review and reflect. It is a process of continuous improvement.
1-observe surface features
2-identify wear type
3-observe wear location
4-list enabling conditions
5-determine what to do next to gather more facts
Your eyes will see many things that your mind will now analyze in future failures.
