When moving fluidized silicon oxide (DE) through pumps, I am interested in extending useful life of the wetted parts. One means is to select materials by use of hardness scales of the base metals. Economics of alloys leads me to consider coatings on wetted parts, such that I could use the softest, cheapest alloys such as ductile iron or cast iron. In the case of either ductile or cast iron, which type of coating and application method would be recommended and proven to yield longest service life?
