摘要
Results from the sealing of porosity by impregnation show that below a certain wetting angle of the sealant, high penetration depths are achieved, However, only sealants with very low curing shrinkages can prevent the transport of electrolyte through the coating, Various sealant types and impregnation methods are discussed, and factors influencing impregnation and sealing ability of sealants are reviewed. Experimental results from the sealing of plasma-sprayed aluminum-oxide coatings are presented.
