The abrasive wear rates of materials may be very simply related to their mechanical properties, provided wear takes place under very simple conditions. However, wear rates in many practical situations can be controlled by effects which either relate to mechanical properties in more subtle ways, or which are controlled by quite different parameters
My input parameters are Load, speed, abrading distance and Grit size. Output parameter I m going to measure is wear loss and friction coefficient. What design of experiment is best suited for this abrasive wear?
To model any kind of wear is a complex and hard task. But I suggest to focus on the relations between load and grit size, improving some ideas from the literature. In this fashion, the angularity should be measured (even controlled) for the tests, if possible.
