Abstract
Process for increasing the density of an article. A coating containing boron nitride and carbon is applied to the article to form a coated article. The coated article is encapsulated. The encapsulated article is subjected to hot isostatic pressing. The coating reduces interaction between the article and the encapsulant during the hot isostatic pressing. The carbon is present in the coating in an amount up to about 30% by weight of the total boron nitride and carbon in said coating.
