Claim 1. A method for forming a nanostructured coating,
comprising
dispersing a nanostructured material in a liquid medium by
ultrasound to form a solution having dispersed therein
nanostructured particles having particle sizes in the range of
from 3 to 30 nanometers;
injecting the solution directly into the feed of a thermal
spray apparatus; and
spray coating the solution onto an article to form a
nanostructured coating on the article.
