The subject invention is directed to a rack for supporting at least one article during a vacuum impregnation process with the article having treated and untreated surfaces. The rack includes a metallic body defining at least one nest for accommodating the article, the nest being configured to support the article under vacuum impregnation conditions. Also, non-metallic bearing surfaces are disposed on portions of the nest. The bearing surfaces are configured to contiguously contact the treated surfaces of the article during the vacuum impregnation process with contiguous contact between the treated surfaces of the article and the metallic body being avoided. Advantageously, with the subject invention, a metallic rack may be utilized which avoids damage to the treated surfaces of an article undergoing vacuum impregnation.
