Yep, some Bridgeport mills have chromed ways, and anodizing is aluminium only.
Though the evidence I have come across is only anecdotal, I believe that scraped cast iron is better for accuracy and provides for better lubrication, as chrome does not have the required surface porosity to retain as much oil as a scraped cast iron surface.
Oh, I second the reference to Abom79 on YouTube. Awesome down to earth guy, and as hobby machinist I love his content. He has a few episodes dedicated to scraping cast iron surfaces that you might find interesting.
