I want to plate machine components, such as spindles, ways and other bearing surfaces, maybe even the leadscrews. So should I go with BN or Hard Chrome?

The Boron solution sound really promising, but I wonder how well it will hold out to being scraped all of the time. As bearing surfaces are scraped each time they rub up against one another.
