Abstract:

Liquid mediums used with opaque porcelain powders are crucial in the application of opaque slurries to oxidized metal surfaces. To augment the effective application of opaque porcelain, liquid mediums should wet oxidized metal surfaces well indicated by a low contact angle. The liquid-metal-surface interaction is a critical factor in the wetting of alloys by liquid suspensions. A multifactorial treatment design was used to evaluate the effects of various metals, liquids, surface preparation, and possible interactions on wetting. Five opaque liquid mediums were evaluated photographically by sessile drop contact angle measurements on five oxidized metal surfaces.
