摘要:
A porcelain enamel coating suitable for use on high-carbon content, heat-rolled sheet steel is provided. The coating includes a ground coat layer for coating directly onto the steel and a cover coat layer. The ground coat layer includes a soft ground coat frit having nickelous oxide dispersed substantially uniformly throughout. The resulting porcelain enamel coating provides good resistance to boiling defects, such as pinholes.
