    Removing cement-like substance from a white-cast iron

    Hi all I have kind of an odd question, it has been quite hard to find an answer for. I'm doing a thesis comparing wear rates and patterns in low stress sliding abrasion between field conditions and labratory-based tests. The field trial uses a quarry 'pugmill', which is essentially a...
